Abstract
Description
Technical Field
[0001] This application relates to designs, systems and methods for a particular type of induction motor, namely, designs, systems and methods for a reverse-wound induction motor. While this type of induction motor has been shown to have high efficiency and very good power factor, this application improves upon these advantages. By achieving and discovering design configurations for this particular type of induction motor, this application discloses arrangements, systems and methods that further improve upon these advantages by transcending and even discarding early understandings of perceived limitations. This application demonstrates that through new understandings, higher efficiencies and better operating results can be achieved for this type of induction motor. Background Art
[0002] Reverse-wound induction motors represent a unique class of induction motors. This class was originally introduced in U.S. Patent 7,034,426 and expanded in U.S. Patent 7,227,288, both of which are incorporated herein by reference. This class of induction motors is disclosed to use a main winding or forward winding, and a unique secondary winding or reverse stator winding. The understanding of this class of motors has only slowly developed. Many years after its introduction, additional discoveries and understandings are still of great significance. International PCT Patent Application US2020 / 013538 and International Patent Publication No. WO2021145864, entitled "Enhanced Reverse-Wound Induction Motor Design, System and Method", are incorporated herein by reference, revealing that new understandings are still occurring many years after their introduction. These new understandings include at least the following: how this class of motors can be enhanced; how they are used to correct for other effects; how they are configured; how they are utilized in a network, etc. These references illustrate the unusual, unforeseen characteristics of this entire class of induction motors. U.S. Patent No. 10903770 reveals that there is much more to be appreciated that is not a simple extension of earlier understanding. That patent reveals and extends knowledge to provide new reverse-wound induction motor designs and uses. The method for efficiently powering a network of electrical devices in U.S. Patent No. 11018612 continues these extensions. U.S. Patent Publication No. 202110320605, entitled "System for Efficiently Powering Enhanced Reverse-Wound Induction Motor Networks," shows how teaching and deeper understanding are often non-intuitive. These extensions, each of which is incorporated herein by reference, advance the state of the art in this unique field and their unique advantages are appreciated as demonstrated by experience in real-world applications and measurement of results in actual use. Although the understanding has matured for decades since its introduction, unforeseen developments continue that exceed and sometimes break the limits of the understanding of this particular class of induction motors.
[0003] The present application discloses that even further extensions can be made. The present application convincingly demonstrates that, although it is non-intuitive to do so, previously stated and perceived limitations can sometimes be discarded to achieve better performance and improved designs. The present application demonstrates that even now, decades after the initial introduction, there are changes and new developments that are not only unexpected, but also contrary to the previously understood limitations of this particular class of induction motors.
[0004] Thus, the present application presents new and unique counter-wound induction motor designs and methods, as well as unique considerations for this particular class of induction motors. Summary of the invention
[0005] Thus, the present application discloses various new designs, systems and methods that provide advantages for counter-wound induction motors. It proposes designs and configurations that can achieve higher efficiency, less slip, and better performance figures than previously achieved by this class of induction motors. Thus, it is an object of the present application to propose an improved counter-wound induction motor that provides enhanced performance by coordinating a counter-magnetic stator system with a more conventional drive stator present in conventional motors that do not have a counter-magnetic stator winding or a counter-magnetic stator system.
[0006] Another object of the present application is to propose a counter-winding design that is actually capable of achieving the long sought after efficiencies from an overall motor efficiency standpoint. These now achievable efficiency levels are often advocated as standard but were previously often only achieved when certain elements or factors that make up the overall motor efficiency were ignored, a critical consideration from an efficiency standpoint.
[0007] To achieve this goal, one object of the present application is to provide an electric motor that provides a high efficiency reverse magnetic stator system. More generally, one object is to provide an electric motor that actually achieves IE4 efficiency or NEMA super premium efficiency standards from an overall motor efficiency perspective. Embodiments of the present application actually achieve IE4 or NEMA super premium efficiency standards from an overall motor efficiency perspective, which has not been achieved before. Of course, this also includes achieving these aspects for the reverse-wound induction motor category.
[0008] Yet another object of the present application is to provide a motor that achieves exceptionally low slip under full load, continuous power conditions. Of course, this also includes achieving these aspects for the reverse-wound induction motor category.
[0009] Two other objectives of the present application fall into the category of advancing the technical development and technical understanding of the entire field of reverse-wound induction motors. First, one objective is to break through a previously believed limitation of reverse-wound induction motors. Here, the objective is to reveal that the limitations believed to exist in reverse magnetic stator systems do not actually apply, and to show that in fact, an oversized element in the system, particularly an oversized reverse stator capacitance, is beneficial in the system. This is noteworthy because it was previously believed that such an oversized element was inappropriate. Consistent with this objective, the present application shows that an oversized reverse winding capacitance is not only possible, but also beneficial when properly selected, enabling the implementation of a reverse-wound motor configured in accordance with the embodiments of the present application. This objective shows how such a level can be determined, and shows the performance levels that can be achieved when these newly discovered configurations are implemented.
[0010] Further, in order to achieve a higher theoretical understanding in the field of reverse-wound induction motors, one goal is to propose new relationships and new factors that have not been previously considered to be important for the configuration of reverse-wound induction motors. This goal not only reveals what types of factors and relationships are actually important, but also shows how to set beneficial values for the reverse stator capacitance to enhance the performance achieved by this new configuration. It includes the goal of providing alternative methods to evaluate and set the values of the reverse magnetic system and the reverse stator capacitance, which can be applied when modifying or newly designing such optimal reverse-wound motors.
[0011] Of course, other goals and objectives of the present application are disclosed throughout the text, clauses and claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It should be understood that the embodiments include various aspects that can be combined in different ways. The following description is intended to list elements and describe some embodiments of the present application. These elements are listed with the initial embodiment; however, it should be understood that they can be combined in any way and in any number to create additional embodiments. The various examples and preferred embodiments described should not be interpreted as limiting the embodiments of the application to only the systems, technologies and applications explicitly described. The one or more specific embodiments shown are only examples. The specification should be understood and intended to support a wide range of claims and each embodiment, and even support claims that may exclude other embodiments. Importantly, merely disclosing an exemplary embodiment does not mean limiting the scope of other broader claims, which may be only one of several methods or embodiments and can be adopted in broader claims or other similar content. In addition, this specification should be understood to support and cover the descriptions and claims of all various embodiments, systems, technologies, methods, devices and applications, which relate to any number of elements disclosed in this application or any subsequent application, each element alone, and any and all various arrangements and combinations of all elements.
[0020] like Figure 1 and Figure 4 As shown, the reverse winding motor (1) operates as a typical induction motor to rotate the rotor (2) by magnetic operation of the drive stator (3), which has at least one drive stator winding (4) inside it, working in conjunction with the rotor (2). It is well known that the induction motor (1) can use magnetically permeable materials at the rotor (2) and the drive stator (3), and the rotor (2) and the drive stator (3) can be considered to form the core (5). It is well known that there is at least one drive stator (3), which has at least one drive stator winding (4). More commonly, the number of drive stator windings is the same as the number of phases of the electrical AC power supply. Most commonly, a three-phase system has three drive stator windings (4). The same applies to the reverse stator winding (14) and reverse magnetic stator system (13) discussed later. Therefore, the drive stator (3) with at least one drive stator winding (4) can be regarded as a forward winding or forward magnetic system.
[0021] As with a standard induction motor, the rotor (2) and the drive stator (3) are contained in a housing or motor frame (6). This motor frame (6) typically encloses at least at least one of the drive stators (3) and the rotor (2). In the category of reverse-wound induction motors, the motor frame (6) may also, and typically, enclose at least part of the reverse-magnetic stator system (13) and one of its components, namely the reverse-magnetic stator (via the reverse-magnetic stator windings (14)). Thus, it will be appreciated that the reverse-magnetic stator system (13) may include at least one reverse-magnetic stator winding (14).
[0022] As discussed below, it is noteworthy that, as the industry has evolved, standardized motor frame sizes have been developed. For standard induction motors, these standardized motor frame sizes can and typically do determine the performance characteristics of the motor: its horsepower or kilowatts, and for a particular voltage, its rated full load current, efficiency, etc. Currently, such motor frames (6) are standardized by standardization bodies such as NEMA and IEC. The embodiments of the present application demonstrate that some of these predetermined values are not appropriate for this class of motors, particularly for the class of motors in the embodiments of the present application. Thus, the present application can be viewed to some extent as breaking the long-standing and widely accepted notion that all motors have similar operating characteristics.
[0023] like Figure 2 As shown, in operation, an induction motor (1) is operated by providing an electrical connection (17) to a power source (7). The power source (7) is typically a public power source, such as an electrical grid (20). The grid or other power source functions to power at least one drive stator (3). The drive stator (3) drives the rotor (2) to rotate by interacting with the rotor (2). In the reverse-wound induction motor category, the power source (7) can also power at least one reverse magnetic stator system (13). This can include powering or energizing the reverse magnetic stator system (13) and the reverse stator winding (14). Regarding more general operation, powering the induction motor (1) typically involves an induction motor drive system (16). The induction motor system drive system (16) can change the operation of the motor in a known manner. It can be a variable frequency drive (VFD) for speed regulation and control, it can change the power factor, it can correct power effects, etc. Such a drive system (16) can be used for both conventional induction motors and reverse-wound induction motor categories.
[0024] As mentioned above, conventional induction motors have at least one forward winding (12). In addition to at least one forward winding (12), the reverse winding induction motor category has at least one reverse magnetic stator system (13), which may and does include at least one reverse stator winding (14). The forward winding (12) and the reverse stator winding (14) are adjacent, such as Figure 4 As shown. It is also possible to use co-wound forward winding and reverse stator winding. Figure 3 As shown in the connection diagram, the reverse stator winding (14) can be configured or connected as a winding in the opposite direction to the forward winding (12) because it presents a magnetic field in the opposite direction. This can only be achieved by reverse connection. Therefore, such a motor can be presented as a motor with reverse windings, and the motor according to the present application can have at least one driving stator reverse winding. The magnetic field windings in opposite directions can therefore act in opposite ways. The motor according to the present application can generally have at least one magnetically conflicting reverse stator winding, that is, the magnetic field of the reverse stator conflicts with other elements in the motor such as the magnetic field to achieve the desired effect. They can also have at least one reverse stator winding (14) that is substantially magnetically coincident with the driving stator, that is, the two magnetic fields occur at least partially simultaneously (that is, considering the current phase difference), are adjacent and may be in close proximity, and are consistent or harmonious to some extent because they work together to not only drive the rotor, but also achieve improved efficiency, improved slip, improved power factor, or coordinate as desired.
[0025] Figure 3 A separate reverse magnetic stator system (13) is shown. The reverse magnetic stator system (13) includes at least one reverse stator winding (14) (typically three for a three-phase power supply). The at least one reverse magnetic stator system (13) may also include at least one reverse stator capacitor (15), or more generally, capacitors. As the reverse wound induction motor class is now more fully appreciated and understood, the at least one reverse stator capacitor (15) may be critical to the improved operation of the reverse wound induction motor class. As will be described later, significant advantages may now be achieved by appropriately selecting the capacitance value of each of the reverse stator capacitors (15). Likewise, for reverse windings, there are typically three reverse stator capacitors (15) for a three-phase power supply. Finally, it is noteworthy that for this class of induction motors, the at least one reverse stator winding (14) is typically referred to as a generator winding because it is reversed and thus, like a motor-generator, may be considered to produce a generator-like result. Importantly, in this class of motors, the rotor is rotated by the interaction of at least one drive stator (14) and at least one reverse magnetic stator system (13).
[0026] With this background knowledge, one can further understand how the present application presents an improved reverse magnetic asynchronous induction motor system, and how it presents a method of providing power from an asynchronous induction motor system or a method of providing power from a reverse magnetic asynchronous induction motor system. These two parallel perspectives, namely the perspective of the device and the perspective of the process or method, show how the present application can be described in a device claim or a method and process claim, where the device is the motor system, and the process or method is the method of providing power from the motor. The discussion in this application - whether provided in device element language or method step language - should be understood to support both. For example, in the above content, the electrical connection (17) to the power supply (7) should be understood to include the steps of electrical connection, the step of providing at least one motor, and the step of powering the device as is well known to those of ordinary skill in the art.
[0027] As described above, one of the objectives of one embodiment of the present application focuses on the aspect of having an opposing magnetic system (8) that is coordinated with the drive stator. This understanding and discovery is important because it changes the entire paradigm of thinking about how to design such motors and now shows a way to optimize the class of opposing wound induction motors in addition to their already significant advantages. This aspect of the present application shows that the limitations previously viewed when designing the opposing magnetic stator system (13) of such motors are not actually limitations. To the extent that it was believed that there were limitations on the current and expected voltage of the opposing magnetic stator system (13), these limitations are no longer necessary. Additionally, new advantages can be achieved by now designing for other criteria and ignoring the limitations previously believed. Thus, the teachings that were previously viewed as limitations no longer apply to some extent.
[0028] like Figure 2As shown, in some embodiments, the at least one reverse magnetic stator system (13) can be configured and treated as at least one reverse magnetic stator system (8) coordinated with the drive stator. This type of modeling and sizing criteria is particularly useful in completely new designs where no previous framework values are available. It is well known that the reverse magnetic stator system (13) has a reverse reactance. This may be caused by factors such as the reverse stator winding (14) and the reverse stator capacitance (15), which are well known in the art. In most categories of reverse-wound induction motors, the reverse stator capacitance (15) is a very important factor because it controls the current and its effects in the reverse magnetic stator system (13). Since the entire field of reverse-wound induction motor categories is not based on a broad mathematical foundation and is largely based on experience, the idea of having at least one reverse magnetic system (8) coordinated with the drive stator is an important understanding. This understanding enables (usually through trial and error and empirical understanding) to achieve significant performance improvements that were not previously expected to be achieved, are non-intuitive, and are in the opposite direction of what the prior art teaches. As noted above, it may eventually be possible to develop and demonstrate equivalent circuits and some estimates of performance and optimum parameters, but at this stage, it is not possible to confidently demonstrate an unquestionably and unmisleadingly accurate theoretical model for the precise reverse-wound magnetic stator system (13) involved, and therefore tabulated values are provided. Rather, the key known is that the coordination of aspects such as one or more capacitive reactances and reverse winding reactances with those factors (reactances, etc.) of the drive stator (3) represents an extraordinary advance. These are not merely advances of degree. From some perspectives, these may ultimately be seen as providing a reverse-wound magnetic stator system (13) that can be used to compensate, enhance, offset, generate or cancel (to some extent) the effects from the drive stator (3) to achieve a significant improvement in the performance of the entire motor (1). From this perspective, the reverse-wound magnetic stator system (13) {although used in the singular, in this and similar contexts it means "at least one"} can be and be configured as a reverse-wound magnetic stator system (8) coordinated with the drive stator. Similarly, as Figure 3 As shown, the opposing stator capacitor (15) can be used and configured as a capacitor (18) coordinated with the drive stator. The optimal value can be most accurately set by trial and error or empirical testing. By powering the opposing magnetic stator system (8) coordinated with the drive stator and then rotating the rotor (2) in conjunction with the drive stator (3), performance improvements can be achieved. Once the other elements of the motor are determined, the performance required for that particular motor configuration can be achieved by adjusting the capacitor (18) coordinated with the drive stator.
[0029] Another object of another embodiment of the present application focuses on aspects of having (at least one) reverse magnetic stator system (9) that achieves at least IE4 total motor efficiency or NEMA super premium total motor efficiency. An interesting feature of the embodiments of the present application is that, perhaps for the first time, through these inventions, at least IE4 total motor efficiency can be truly achieved by the motor itself. Although other manufacturers claim to have IE4 efficiency, it can be understood with further understanding that the efficiency they claim is generally not the "total motor efficiency", that is, the efficiency of the entire motor in isolation without considering any drive (16) elements, any efficiency defined outside the network, any auxiliary components. For example, in some cases, the total motor efficiency can be considered to use apparent power, that is, active power plus reactive power or complex power, etc. Surprisingly, through embodiments of the present application, individual motors can now achieve total motor efficiencies that meet or exceed IE4 or NEMA super premium established levels when fully loaded. As described above, this is achieved by providing a reverse wound induction motor category and configuring the reverse magnetic stator system (13) to be an IE4 total motor efficiency reverse magnetic stator system (9), and perhaps also configuring the reverse stator capacitor (15) to be at least an IE4 full system efficiency capacitor (19). Again, this can be achieved by empirically setting components such as the reverse stator winding (14) and reverse stator capacitor (15) to obtain the desired efficiency and establishing them as at least an IE4 total motor efficiency reverse magnetic stator system (9) and at least an IE4 full system efficiency capacitor (19). As with the drive stator coordinated embodiment, by powering at least an IE4 total motor efficiency reverse magnetic stator system (9), including or resulting from at least an IE4 full system efficiency capacitor (19), and then rotating the rotor (2) in coordination with the drive stator (3), improved efficiency can be achieved, as well as significant total motor efficiency reaching or exceeding IE4 levels. Of course, the same is true for NEMA super premium levels.
[0030] When considering efficiency and setting renewal levels, it is important to understand the impact of standardized enclosures (or frames) (6). These dimensions are set by standardization bodies (such as NEMA and IEC) and have traditionally governed performance based on motor type (number of poles / speed, voltage, supply frequency, etc.). From this perspective, the frame determines not only the horsepower or kilowatts of the motor, but also its efficiency. This is typically achieved through a nameplate process where each motor has a nameplate (21) that specifies a number of parameters. Although these could be considered minimum values, they are often the only values that are actually achieved for economic and other reasons. If a manufacturer fails to achieve these standard nameplate (21) values for that type of motor and these conditions (voltage, frequency, etc.) in a specific size frame (6), then their motor will not be sold. Interestingly, this nameplate process is performed by standardization bodies (such as NEMA and IEC) based on standardized enclosure or frame (6) dimensions. Newer efficiency levels of IE4 efficiency are set through the IEC's International Energy Efficiency Classes (IE Codes), such as IEC Standard 60034-30, last revised in 2014, IEC / EN 60034-30-1:2014, and NEMA 10011-22. NEMA also has conceptually similar values and has an efficiency standard similar to the IEC's IE4 level, called "super premium" efficiency. In the context of embodiments of the present application, the term high efficiency for such reverse magnetic stator systems should be understood to cover similar IE4 or NEMA super premium levels and NEMA frame sizes by analogy.
[0031] For some of the present embodiments, values for efficiency, slip and even power factor are given relative to more conventional non-reversed winding class motors. When used as a comparison, a so-called "at least IE4 overall efficiency" reversed magnetic stator system (9) is used to compare these embodiments of the present application to the non-reversed winding induction motor class of comparable motors, i.e. motors with similar nameplate parameters (frame, number of poles, speed, voltage, frequency, etc.) but without the changes that would make them reversed winding class motors. Changes that would be required, such as to provide space and insert the reversed magnetic stator system (13), etc., are not included, but everything else is the same as for the standard motor, including the operating conditions. For example, a NEMA frame size of 184T may have the following nameplate parameters: HP 5, RPM 1748, Enclosure TEFC, Design B, Frame 184T, Current 7.0A, Phases 3, Frequency 60Hz, Continuous Operation, Voltage 460V, Type P, Ambient Temperature 40°C, Service Factor 1.15, Insulation Class F, Efficiency 82.5%, Power Factor 80%, DE Bearing 35BC02JGG30A26, ODE Bearing 3OBC02JGG3OA26. This nameplate indicates that this is a 5 HP motor that operates at an efficiency of 82.5%. If this motor is converted to the reverse-wound induction motor category, then the new motor according to embodiments of the present application (e.g., a 5 HP motor operating at 460V, 60Hz, 3 phases) will be compared to this 82.5% efficiency, and the efficiency improvement may be quantitatively stated. The many factors that determine the committed nameplate value are well known, can be calculated from design or signature analysis software, can be newly derived, and for existing frameworks, these values are published in various nameplate interpretations and standards, and these factors are taken into account when evaluating what is a comparable motor and how to quantitatively determine improvements.
[0032] To further understand the improvements of the embodiments of the present application, it is important to understand how the improvements exist and how difficult it is to achieve these improvements when the performance level is already high. Although the embodiments of the present application can increase the efficiency by 3-5 percentage points for higher power motors (over 100 horsepower) and 5-7 percentage points for lower power motors, these estimates are only approximate numbers. Instead, it is better to understand from the perspective of the percentage to perfection. For example, for a motor that already has 94% efficiency, increasing the efficiency by 2 percentage points - from 94% to 96% - may not seem difficult, but in fact, this needs to be viewed from the perspective of how much 2% increases the remaining 6%. Adding 2 percentage points to a motor that is already 94% efficient is very different from adding 2 percentage points to a motor that is already 82.5% efficient. For a 94% efficient motor, those 2 percentage points represent a 33% improvement (to perfection, that is, 33% of 100% efficiency). Therefore, the key is the gap to perfection, that is, 100% efficiency, and how difficult it is to achieve those last few percentage points. Therefore, the angle that best allows people to understand this difficulty is the percentage from the existing or unimproved motor level of the present application to perfection. Although it is only 6% to go from 94% to 100%, this is very difficult and may actually be impossible for a single motor. Therefore, for a 94% motor, the 33% improvement (towards 100% or perfection) is only 2%, but this number is actually huge and should be understood as a 33% improvement on the existing 94% level. Against this background, the advantages of several types of improvements implemented in the embodiments of the present application can be understood: efficiency improvement, slip improvement, and power factor improvement. Each improvement will be discussed in turn. Interestingly, while some improvements to the "perfect" level represent difficult levels to achieve, some are actually achievable (such as power factor, which is a special element of the reverse-wound induction motor category, and this is one of the reasons why they should be classified separately).
[0033] In the context of embodiments including an inverted magnetic stator system (9) or similar system having at least IE4 overall motor efficiency, and overall motor efficiency improved to at least IE4 standards, the efficiency improvement achieved can be best understood by comparing the efficiency levels of the motor frame before and after the inverted magnetic stator system is used, specifically, the efficiency improvement level can be determined when the motor frame (or its equivalent new design frame) is used at rated full load with a comparable motor standard nameplate efficiency value without the inverted magnetic stator system (i.e., conventionally). Thus, if the constant power efficiency at rated full load is improved by at least a 20% efficiency improvement toward perfect, i.e., 100% efficiency (e.g., from 85% to 88%, or from 95% to 96%) compared to the comparable motor standard nameplate efficiency value, other values are possible. Here, embodiments may achieve such 20% improvement, 33% improvement, 40% improvement, or even 50% improvement (e.g., from 80% to 90%, or from 94% to 97%), all compared to comparable motors that do not use an inverted magnetic stator system. It is understood here that such efficiency improvements to perfect percentages may be achieved through the teachings of the present application and beyond previously believed limitations. When appropriate capacitors (19) or similar components are provided that provide at least IE4 overall motor efficiency, when an inverted magnetic stator system (9) or similar system is provided that provides at least IE4 overall motor efficiency, and even when at least one efficiency optimized inverted magnetic stator system is provided, motor efficiency may be optimized to "high efficiency", even though higher efficiencies may be achieved, even though the optimization does not achieve perfect overall motor efficiency.
[0034] Similar to the "percent to perfection" approach, it is also possible to set absolute values for efficiency for motors with specific powers and other conditions. In this regard, for motors at rated full load, at constant power and at 100% rated load, the following values for total motor efficiency can be selected: at least 98.5% efficiency for motors with rated full load powers exceeding 2 MW; at least 99% efficiency for motors with rated full load powers exceeding 2 MW; at least 98.5% efficiency for motors with rated full load powers between 1 MW and 2 MW; at least 99% efficiency for motors with rated full load powers between 1 MW and 2 MW; at least 98% efficiency for motors with rated full load powers between 500 kW and 1000 kW; at least 98.5% efficiency for motors with rated full load powers between 500 kW and 1000 kW; at least 90% efficiency for motors with rated full load powers between 100 kW and 500 kW. kW, at least 97.5% efficiency for motors rated between 100 kW and 500 kW; at least 98% efficiency for motors rated between 20 kW and 100 kW; at least 97% efficiency for motors rated between 20 kW and 100 kW; at least 97.5% efficiency for motors rated between 20 kW and 100 kW; at least 96.5% efficiency for motors rated between 5 kW and 20 kW; at least 97% efficiency for motors rated between 5 kW and 20 kW; at least 96% efficiency for motors rated between 1 kW and 5 kW; at least 96.5% efficiency for motors rated between 1 kW and 5 kW, etc. Likewise, efficiency characteristics that represent progress toward perfect efficiency that exceed certain current IEC / EN 60034-30-1:2014IE4 efficiency standards may also be achieved, whereby at least 20%, 33%, 40% and 50% efficiency improvements may be achieved when the motor system motor frame is used in a comparable motor that does not use a reverse magnetic stator system, compared to the IEC / EN 60034-30-1:2014IE4 efficiency standard.
[0035] Similar to the efficiency improvements just discussed, embodiments may also be configured to improve slip (i.e., less slip at a given, typically full rated load). Again, this may be considered from the perspective of an improvement to a percentage of perfection, as well as other perspectives. Here, embodiments may include at least one full rated load slip minimized reverse magnetic stator system (10), and may include at least one slip minimized capacitor (11). Again, components such as the reverse stator windings (14) and particularly the reverse stator capacitors (15), as the slip minimized capacitors (11), may be set empirically to obtain the desired slip and established as at least one full rated load slip minimized reverse magnetic stator system (10) and at least one slip minimized capacitor (11). As with other embodiments, by energizing at least one rated full load slip minimized reverse magnetic stator system (10), including or caused by at least one slip minimized capacitor (11), and then rotating the rotor (2) with the drive stator (3), while incorporating at least one rated full load slip minimized reverse magnetic stator system (10), improved slip performance can be achieved. Likewise, the level achieved can be understood in the context of a motor frame having a comparable conventional, non-reversed wound induction motor standard nameplate or otherwise determined slip value (generally the difference between the comparable motor nameplate (21) speed at rated full load and the no-load drive speed, which is determined by the number of poles and line frequency and is generally apparent from the nameplate load speed), when the motor system motor frame is used in a situation with a comparable motor nameplate (21) without using a reverse magnetic stator system (i.e., conventionally). Here, embodiments of the present application improve upon previous reverse wound motor designs and exceed previously anticipated limitations. Thus, for a motor frame having a comparable motor's standard nameplate slip value in a comparable motor not using an opposing magnetic stator system, slip can be improved by at least 20%, 50%, 75%, 90%, and 95% slip improvement over the comparable motor's standard nameplate slip value at full rated load, toward zero slip (e.g., away from perfection). Such values can also be achieved for smaller loads such as 75% rated load. And as with efficiency, there is an absolute value for slip improvement. Here, such an embodiment can achieve less than 0.5%, 0.3%, or 0.1% slip over 75% of its rated full load, and likewise achieve less than 0.5%, 0.3%, 0.1%, and even 0.06% slip at rated full load for certain motors.
[0036] Next, even power factor can be considered, whether from an improvement to a percentage of perfection or other perspective. Similarly, when the motor system motor frame is used with comparable motors and motor conditions that do not use an opposing magnetic stator system, each motor frame typically has a comparable motor standard nameplate power factor value at rated full load. By setting the opposing magnetic stator system (13) and / or opposing stator capacitance (15) empirically or otherwise, as described above, the embodiments herein can achieve a constant power, power factor at rated full load that is at least 20%, 50%, 75%, 90%, or even 100% (i.e., a power factor of 1.0!) better than the comparable motor standard nameplate power factor value, toward a 1.0 power factor (e.g., the difference from perfection).
[0037] As mentioned, setting the reverse stator capacitance (15) is an important element in configuring a reverse-wound motor according to an embodiment of the present application. An important aspect in determining the appropriate reverse stator capacitance (15) may be that the forward winding (12) and the reverse stator winding (14) may have different winding wire cross-sectional areas. The purpose of this is to enable the reverse stator winding (14) to fit into the frame (6). Here, the ratio of the forward winding wire cross-sectional area or the drive stator wire cross-sectional area (22) to the reverse winding wire cross-sectional area or the reverse stator winding wire cross-sectional area (23) can be set to approximately 2. This can represent a practical compromise between space, reactance, and effect in the category of reverse-wound induction motors. It is based on this ratio that many potential values are explained, although this is not considered a limitation unless explicitly stated.
[0038] As mentioned previously, previous limitations on reverse-wound motor components are now proven to be non-important. Even relationships that were previously taken for granted are now proven to be suboptimal. By overcoming previous limitations and designing based on newly understood relationships, new levels of performance can be achieved. This is most evident in the limitations and expected optimal design relationships for reverse stator capacitance (15). These understandings and discoveries are significant because they change the way such components can be optimally configured for these motors. Importantly, the optimal values discovered are significantly different from those previously thought to be appropriate. First, these new values break through previous limitations. In some cases, they are even one or two orders of magnitude different from previous values. This can lead to significant improvements in performance, especially in areas that asymptotically approach ideal values (such as efficiency) where the perspective of percentages to perfection is relevant, making small improvements represent large and increasing percentage improvements. Second, these new values are based on completely different relationships than before. These new relationships reveal that the optimal design requires a reverse stator capacitance (15) that varies based on different parameters and even within a specific voltage range. This aspect of the present application demonstrates that previous relationships and understandings of limitations regarding configuration of counter-stator capacitance (15) in a counter-magnetic stator system (13) are no longer necessary, and that actual components differ significantly (sometimes by orders of magnitude) from those previously applied.
[0039] The unique properties beyond these perceived limitations are non-intuitive because these prior limitations would lead one away from embodiments of the present application. Again, this is not simply a matter of degree; rather, it is a different relationship that sometimes results in a very different adjustment to the size of one or more reverse stator capacitors (15). For reverse wound induction motors, it is well known that at least one reverse stator winding (14) can be connected to at least one capacitor (15). Typically, each of the reverse stator windings (14) is connected in series with a capacitor (15). Surprisingly, in order to achieve new goals and obtain a new type of reverse magnetic stator system (13) and / or a new type of reverse stator capacitor (15), as described in various embodiments, it is necessary to abandon previous limitations and relationships. Now, in view of this new discovery, embodiments can include an oversized capacitor, i.e., a capacitor that is larger than previously taught and has no previous maximum limit value. In such embodiments, the present application may be described as relating to an electric motor having at least one reversed stator winding (13) configured as at least one oversized, reversed magnetic effect enhanced reversed magnetic stator system (24), and to any extent beyond that assumed limit, performance may be enhanced and improved. Embodiments may achieve the above performance by configuring at least one reversed stator capacitor (15) as at least one oversized, reversed magnetic effect enhanced capacitor (25). Quantitatively, in some of these embodiments, this is a reversed stator capacitor (15) having a microfarad value as described in Tables 1 and 2. It may be more precisely determined by the relationships discussed later. These values have never been attempted before (of course, this is a new relationship and the casual effort is not well known), but these values are significant because they result in significant improvements. The at least one oversized, reversed magnetic effect enhanced capacitor (25) may be sized according to the microfarad (MFD or μF) values shown in the table for the stator coordinated configuration, or determined by the relationships discussed later.
[0040] The teachings of U.S. Pat. No. 10,903,770 (although the development of such motors was largely empirical) had determined that exceeding a certain value was erroneous. In fact, the present disclosure teaches, first, that such a limit is not optimal for maximizing performance and actually limits the performance that can be achieved with a reverse-wound induction motor. Second, unlike previous teachings, the present disclosure teaches that even using a multiplier within the design reverse-wound motor voltage range is not optimal if it is a constant value. Third, unlike previous teachings, it teaches that even the previous complex conjugate or linkage term is suboptimal. First, using a different range multiplier than before and ultimately deriving a capacitance value that exceeds the previous "limit" is not prohibited, but is actually better. Second, the new range multiplier is not a constant value, but varies in a step-like manner over a particular voltage range. Third, the previous complex conjugate or linkage term is replaced by an entirely new relationship that surprisingly and non-intuitively relates the reverse-wound parameters to the frame for a non-reverse-wound motor for a retrofit design or a design using an existing frame. This new relationship results in very different values and very different performance. The prior art taught a fixed multiplier, while the new disclosure teaches the use of an entirely different multiplier, and that this multiplier actually improves motor performance as it increases over a particular range of motor supply voltages (from 900 volts to 2300 volts). It is noteworthy in this regard that the prior art taught a maximum reverse stator capacitance (15) value, in microfarads, equal to that old maximum multiplier times the motor's operating current rating in amperes, times a ratio times the motor's rated full load current in amperes at that rms rated optimum operating motor voltage. Now, the new disclosure reveals that the optimal capacitance size from a model can actually be derived from a different, variable range multiplier, times different factors for different motors in the model. These factors can include power, voltage, efficiency, and power factor for different motors. Surprisingly, the efficiency and power factor parameters are not even the values that apply to the final reverse-wound motor. In accordance with this new aspect of the present application, it has been discovered that reverse-wound motors and their performance can be optimized. This is achieved by appropriately setting new values for the reverse stator winding capacitance (15). This new relationship can even be understood at different levels of granularity.
[0041] This new type of relationship, which fits into the existing framework, can be understood in order. Initially, the microfarad value of the reversed stator capacitance (15) for each phase of the motor can be determined from the parameters of a comparable supplied power (similar voltage and frequency) and, for some aspects, number of poles, but a different motor type, an induction motor. Interestingly, some of these parameters are not applicable to the improved reversed magnetic asynchronous induction motor. These parameters can be determined from known design criteria and calculations for standard comparable motors. For example, these parameters can be determined using conventional (non-reversed winding) relationships, perhaps with the aid of induction motor design or analysis software such as Ansys Maxwell currently available from ANSYS. TM Software) can also be used for calculations, or electrical characteristics analysis (ESA) software (such as ALL-TEST PRO TM Software or On-Line III TM Software, which is currently provided by ALL-TEST Pro, LLC). It can also be determined from the nameplate that would normally appear on the frame. With this new relationship, the nameplate parameters of the induction motors of different motor types can be used to determine a more optimal capacitance value. Multiple parameters can be used. The capacitance magnitude is determined at least in part by the nameplate voltage of the induction motors of the different motor types, at least in part by the inverse of the cube of the nameplate voltage of the induction motors of the different motor types, at least in part by the nameplate power of the induction motors of the different motor types, at least in part by the nameplate efficiency and power factor of the induction motors of the different motor types, at least in part by the inverse of an amount equal to the nameplate efficiency of the induction motors of the different motor types multiplied by the nameplate power factor, and at least in part by a multiplier multiplied by a value determined by the nameplate parameters of the induction motors of the different motor types. While each of these parameters can be arranged into relationships in sequence, a preferred final relationship is as follows: One or more capacitance values are determined, each having a microfarad value that is approximately equal to a variable multiplier that varies stepwise over a particular nameplate voltage range, multiplied by the framework's standard nameplate motor power in watts, multiplied by the reciprocal of a quantity equal to: the cube of the framework's standard nameplate motor voltage in volts, multiplied by the framework's standard nameplate motor efficiency in decimals, multiplied by the framework's standard nameplate motor power factor in decimals.
[0042] There are three noteworthy and unusual aspects in this regard. First, this relationship equates the absolute values of units that are different in at least three dimensions and are not expected to be related, namely, microfarads and the inverse cube of watts and volts. The values of certain composite values for certain motors produce reverse stator capacitance (15) in microfarads. As illustrated by the following two examples, using the preferred multipliers, if a suitable motor frame is rated at 5 horsepower (3730 watts), 460 volts, 89% efficiency (0.89 decimal), and 83 (0.83 decimal), then a capacitance of 10.6 microfarads (commonly referred to as MFD) is optimal. Similarly, if another suitable motor frame is rated at 700 horsepower (522,000 watts), 3300 volts, 95.5% efficiency (0.955 decimal), and 88 (0.88 decimal), then a capacitance of 27.1 microfarads is optimal. As mentioned below, this can be a margin of error of plus or minus 10%.
[0043] Next, for this model, the guidance is not even the type of motor being designed, it is not a counter-wound motor, but a completely different type of motor that is designed or configured based on the frame size selected. This different motor, a motor that is different in type, is used to find the MFD value that determines the capacitance value of a completely different motor. The capacitance is determined by an induction motor of equivalent supply power but a different type of motor type.
[0044] It is surprising that non-similar motors set the value for this model and sizing criteria. For retrofit designs and designs using a fixed motor frame, the pre-reversed winding design motor using that particular frame determines the initial size of the reverse stator capacitance (15). Although that non-reversed winding motor is comparable in terms of similar power and voltage, it is still a different motor and even uses inappropriate efficiency and power factor values because the final reversed winding motor will have higher efficiency and better power factor. As is well known, motors usually have nameplates when used as standard non-reversed winding motors with various parameters marked on the nameplate. These parameter values are used when evaluating the reverse stator capacitance (15) value for a reversed winding motor configured using this model. For new designs without an existing frame, a similar frame can be used or a separate model can be provided, which is the stator coordination model. The values and results obtained by the two models are similar, so the qualifiers "approximately" or "approximately equal" are appropriate.
[0045] As mentioned, for different types of motor models, a further refinement of the relationship is to use a specific type of multiplier to determine the optimal size of the reverse stator capacitor (15) in the reverse winding motor. As can be understood from the above, in the initial embodiment, this multiplier can be varied based on the nameplate voltage or calculated power supply. For some embodiments, it is more preferred to use a multiplier that varies with voltage. As mentioned below,
[0046] The size can be increased to achieve a near Joule effect breakdown current, which can also be referred to as a capacitance value near Joule effect breakdown. In this upper limit case, the microfarad value of one or more capacitors can be close to the capacitance value that produces a Joule effect breakdown current density in the reverse winding or more generally in the reverse magnetic stator system (13).
[0047] Another novel aspect regarding the sizing of the counter stator capacitance (15) is that for certain embodiments, the multiplier may be a multiplier that varies with certain parameters. Figure 6 An example of this is shown. In preferred embodiments of these inventions, the multiplier is a supply voltage dependent multiplier, i.e. it varies based on the voltage on the frame nameplate. Thus, this multiplier can be considered a voltage dependent multiplier.
[0048] In a further embodiment, it has been found that the change in the multiplier can be in steps, for example Figure 6 The step function (39) at a position on the step function line (39) shown in , or as Figure 6 All curves in FIG. 3 show a stepwise approach of changing only the multiplier value within a certain range (these are just some of the possibilities). In general, such an embodiment may include a stepwise variable multiplier. This multiplier may vary from a lower level (31) to a higher level (32). As before, this may apply to all multiplier options, so that, for example, in a multiplier that appears to be the most ideal base or lower level (31), there may be a lower step multiplier value of approximately 183,000. The higher level (32) may be an upper step multiplier value of approximately 1,358,000. Of course, this relationship may be adjusted based on changes in units (such as horsepower to kilowatts, microfarads to farads, etc.), but these known quantitative changes are equivalent to those discussed here. In addition, when determining capacitance values, it should be understood that the terms "about" and "approximately equal to" can be quantitatively reduced to within ten percent (10%) or fifteen percent (15%) of the initially determined value.
[0049] Interestingly, in the context of certain embodiments, the variation may be limited, and is presently preferred to be limited to a particular voltage range. Thus, an embodiment may present a multiplier that varies with the supply voltage range. And, further, within this range, the multiplier may rise in a variety of ways, thereby roughly presenting a variable multiplier that rises with the supply voltage range. This rise may be limited to a particular supply voltage range, i.e., values outside of the range (outside of the range (33) and (35)) are relatively constant at the upper limit (32) or the lower limit (31). Thus, an embodiment includes a limited voltage range rising variable multiplier. Again, the ranges and values may be determined empirically, however, the preferred embodiment of the present application has a lower limit rising range value of approximately nine hundred volts and an upper limit rising range value of approximately two thousand three hundred volts. This is in Figure 6 . Within the range or region of variation, the variation can be linear, as shown by the linear slope line (37). The slope can vary, but this shows a linearly varying step multiplier. Other lines, such as (36) and (38), show various smoothed versions with known smoothing techniques applied. All of these are some of the more general group in which there is a smooth step multiplier. All of these can be achieved within a specific range, such as the 900V to 2300V range mentioned earlier. Thus, there can be a linear voltage range rise variable multiplier and a smooth range rise variable multiplier. The center of the variation (34), whether it is a step, linear rise or smooth step multiplier, can be located at various values, including but not limited to a 900V value, a range midpoint value, a 1550V value (such as Figure 6 As shown in the middle line (34), it may even be at a value of 2300 V. Thus, using this description it may be interpreted that 1550 V is only an example and there may be a rise centered around 1550 V.
[0050] As described above, the value of the reverse stator capacitance (15) can be achieved close to the capacitance value that produces the Joule effect breakdown current density in the reverse winding. Improved performance can be achieved by powering at least one oversized, reverse magnetic effect enhanced reverse magnetic stator system (24), including or caused by at least one oversized, reverse magnetic effect enhanced capacitor (25), and then rotating the rotor (2) through the interaction of the drive stator (3), while incorporating the oversized, reverse magnetic effect enhanced reverse magnetic stator system (24). In addition, as previously described, the results generally achieved are accomplished through empirical methods. These results are non-intuitive compared to previous understandings of the category of reverse wound induction motors.
[0051] Setting the value to a level close to the Joule effect breakdown current density of the current in the reverse stator winding (14) is a new understanding for reverse wound motors. The Joule effect breakdown current density is the level for each type and size of conductor, which is the point at which normal Joule effect heating (I 2 R) will break down as the conductors begin to fail under their specific conditions and environment. For reverse wound induction motors, it has now been determined that it is critical to avoid current densities approaching Joule effect breakdown, otherwise excessive heat may be generated. Obviously, this may depend on the conditions of the motor (such as altitude, etc.) and the type of housing used, but now, not only has the previously believed limit been broken, but improved performance can be achieved by establishing a reverse magnetic stator system close to the maximum current density or a reverse magnetic stator system (13) close to the Joule effect breakdown current density. The previously believed limiting values are now considered to be suboptimal because they may be far below the current density close to the Joule effect breakdown current density now considered ideal. Thus, embodiments may have at least one reverse magnetic stator system (26) close to the Joule effect breakdown current density, and may even have at least one capacitor (27) close to the Joule effect breakdown. Improvements may be achieved by powering the at least one reverse magnetic stator system (26) close to the Joule effect breakdown current density and rotating the rotor (2) through the interaction of at least one drive stator (3) and at least one reverse magnetic stator system (26) close to the Joule effect breakdown current density. In order to establish at least one reverse magnetic stator system (26) close to the Joule effect breakdown current density, at least one capacitor (27) close to the Joule effect breakdown, or at least one capacitor close to the Joule effect breakdown, the motor can select a capacitance value of about 99%, 98%, 95%, 90%, 85%, or even 80%, which can affect the Joule effect breakdown current density in the reverse stator winding (14). This can be regarded as presenting at least one reverse magnetic stator system (26) close to the Joule effect breakdown current density.
[0052] Finally, some representative motor capacitance values are shown in Tables 1 and 2 as examples of the types of capacitance that may represent the reverse stator capacitance (15) in certain embodiments described herein. These can be used as a starting point for empirical work to find optimal values. And for these, it should be understood that these are estimates based on certain configurations of stator coordination methods or models to determine capacitance values.

[0324] It can be easily understood that the basic concepts of the various embodiments of the present application can be embodied in many ways. It relates to both powering techniques for reverse-wound induction motors and reverse-wound induction motors for achieving appropriate powering. In the present application, powering techniques are disclosed as part of the results achieved by the various described devices and as inherent steps of use. They are simply the natural result of using these devices as intended and described. In addition, although some devices are disclosed, it should be understood that these devices not only implement certain methods, but can also be varied in many ways. Importantly, for all of the above, all of these aspects should be understood to be included in the present disclosure.
[0325] The discussion included in this application is intended to serve as a basic description. The reader should note that the specific discussion may not explicitly describe all possible embodiments; many alternatives are implicit. In addition, the discussion may also fail to fully explain the versatility of the various embodiments of the present application, and may not explicitly show that each feature or element can actually represent a wider range of functions or a large number of alternatives or equivalent elements. For example, degree terms, approximate terms and / or relative terms may be used. These terms may include words such as "substantially", "about", "only". These words and such words should be understood to cover considerable amounts, quantities, sizes, etc. in the dictionary sense, as well as terms that cover to a large extent but not completely in line with the specified content. Further, in this application, if or when used, degree terms, approximate terms and / or relative terms should be understood to also cover more precise values or even quantitative values, including various levels of precision and covering claims that may involve multiple quantitative options and alternatives.
[0326] When an application is described in device-oriented terms, each element of the device implicitly performs a function. Not only should apparatus claims for the described device be included and added, but also method or process claims should be included to cover the functionality of the implementation as well as the functions performed by each element. Neither the description nor the terminology is intended to limit the scope of the claims that will be included in any subsequent patent.
[0327] It should also be understood that various changes can be made without departing from the essence of the various embodiments of the present application. These changes are also implicitly included in the specification. They still fall within the scope of the various embodiments of the present application. Based on this understanding, the reader should note that this disclosure should be understood to support any subsequent patent submission, which may seek as broad a claim basis as possible, is considered to be within the scope of the applicant's rights, and may be intended to obtain patents covering many aspects of the embodiments of the present application, whether independently or as a whole system.
[0328] Further, each of the various elements of the present application embodiment and claim can also be realized in a variety of ways. In addition, when used or implied, the element should be understood to cover single structures and multiple structures that may be physically connected or not physically connected. The present disclosure should be understood to cover each such change, whether it is a change in the embodiment of any device embodiment, a change in the method or process embodiment, or a change in any element of these. In particular, it should be understood that because the present disclosure relates to the elements of the various embodiments of the present application, the words of each element can be expressed in equivalent device terms or method terms-even if only the function or result is the same. Such equivalent, broader and even more general terms should be considered to be included in the description of each element or action. Where necessary, such terms can be replaced to clarify the implicit wide coverage enjoyed by the present application embodiment. For example, it should be understood that all actions can be expressed as the means of taking the action or the elements causing the action. Similarly, each disclosed physical element should be understood to cover the disclosure of the action promoted by the physical element. With regard to the last aspect, taking "power supply" as an example, it should be understood to cover the disclosure of the action of "supplying power", whether or not it is explicitly discussed, and vice versa, if the action of "supplying power" is effectively disclosed, such disclosure should be understood to cover the disclosure of "power supply" and even, if necessary, "power supply means" (recognizing the legal limitations involved therein). It should be understood that these changes and alternative terms are explicitly included in the description. Further, each such means (when explicitly described with words with such limitations) should be understood to cover all elements capable of performing a given function, and all descriptions of elements that perform the described function should be understood as non-limiting examples of means for performing the function. As other non-limiting examples, it should be understood that the claim elements may also be expressed as any of the following: elements configured to provide or even achieve a specific result, use, purpose, situation, function or operation, or as components capable of achieving a specific activity, result, use, purpose, situation, function or operation. All of these should be understood to be within the scope of the present disclosure and written description.

[0340] Therefore, it should be understood that the applicant is entitled to assert and propose claims including but not limited to the following: i) each induction motor device disclosed and described in this application; ii) the related methods disclosed and described; iii) similar, equivalent and even implicit changes of each device and method; iv) alternative designs to achieve the functions disclosed and described; v) alternative designs and methods implicit in the disclosed and described content to achieve the functions; vi) each feature, component and step shown as a separate and independent invention; vii) applications enhanced by the various systems or components disclosed; viii) the resulting products produced by these processes, methods, systems or components; ix) each system, method and element shown or described, now applied to any specific field or device mentioned in this application; x) substantially the same methods and devices as described above and described with reference to the accompanying examples; xi) devices for performing the methods described in this application, including means for performing the steps; xii) various combinations and arrangements of each element disclosed; xiii) each possible dependent claim or concept, as a dependent item of each independent claim or concept; and xiv) all inventions described in this application.
[0341] With respect to claims now or later filed for examination, it should be understood that, for practical reasons and to avoid a substantial increase in the burden of examination, an applicant may at any time file only the initial claims, or only the initial claims with initial dependencies. The Office and any third party interested in the potential scope of this or a subsequent application should understand that broader claims may be filed later in this case, in a case claiming priority to this case, or in any continuation, notwithstanding any preliminary amendment, other amendment, claim language, or argument. Thus, there is no intent to abandon or transfer any potential subject matter throughout the pendency of any case. It should be understood that if or when broader claims are filed, it may be necessary to revisit any previously considered relevant prior art, because if any amendment, claim language, or argument raised in this or any subsequent application is considered to be raised to avoid such prior art, such grounds may be eliminated by later filed claims or similar content. Examiners and anyone else interested in the potential scope of existing or subsequent coverage, or considering whether there was any possibility of abandonment or transfer of potential coverage at any time, should be aware that no such transfer or abandonment was ever intended or existed in this or any subsequent application. Limitations such as those found in Hakim v. Cannon Avent Group, PLC, 479 F.3d 1313 (Fed. Cir. 2007) or similar cases are expressly inapplicable in this application or any subsequent related matter. In addition, it is understood that support exists to the extent required by new content law, including but not limited to Article 123(2) of the European Patent Convention and 35 U.S.C. 132 or other such law, to allow various dependencies or other elements presented as dependent clauses or elements under any independent claim or concept to be presented as dependent clauses or elements under any other independent claim or concept. Whenever any claim is drafted in this application or any subsequent application, it is understood that the applicant intends to capture as broad and comprehensive a scope of protection as is legally available. To the extent that substantial equivalent substitutions are made, to the extent that the applicant has not actually drafted any claim to literally cover any particular embodiment, and where otherwise applicable, the applicant should not be construed as in any way intending or actually waiving such coverage, as the applicant may not be able to anticipate all possibilities; nor should one skilled in the art reasonably expect to draft a claim that literally covers such alternative embodiments.
[0342] Further, if or when used, the transitional phrases "comprising," "including," "containing," "characterized by," and "having" are intended to maintain the "open" claims herein under conventional claim construction, including that discussed in the Manual of Patent Examining Procedure (MPEP) §2111.03. Thus, unless the context requires otherwise, it should be understood that the terms "comprise," or variations thereof, "comprises," "comprising," "include," or variations thereof, "includes," "including," "contain," or variations thereof, "contains," "containing," "characterized by," or variations thereof, "characterizing by," "have," or variations thereof, "has," "having" are intended to imply the inclusion of stated elements or steps or combinations of elements or steps, but not the exclusion of any other elements or steps or combinations of elements or steps. These terms should be interpreted in the broadest form so as to provide applicants with the broadest coverage permitted by law. Additionally, the "selected from" language should also be understood to support explicit limitation to narrower group-oriented / Markush language if desired, such as a group "consisting of" or "consisting essentially of" items a, b, and c, etc.
[0343] The phrase "or any other claim" is used to provide support for any claim to be dependent on any other claim, such as another dependent claim, another independent claim, a previously listed claim, a subsequently listed claim, etc. As a clarifying example, if a claim is dependent on "claim 9 or any other claim" or something similar, it can be redrafted as dependent on claim 1, claim 8, or even claim 11 (if any) as needed and still fall within the scope of the disclosure. It should be understood that this phrase also provides support for any combination of elements in the claims, and even provides the appropriate antecedent basis required for certain claim combinations (such as method, apparatus, process, etc. claims).
[0344] Finally, all claims issued at any time in this application are now incorporated herein by reference as part of the description of the various embodiments of the application, and applicants expressly reserve the right to use all or part of such incorporated content as additional description to support any or all claims or any elements or components thereof, and applicants further expressly reserve the right to move any or all of such incorporated content or any elements or components thereof from the description into the claims or vice versa to define the subject matter sought to be protected by this application or any subsequent continuation, divisional, or continuation-in-part thereof, or to obtain any benefit, reduce costs under, or comply with patent laws, rules, or regulations of any country or treaty, and such incorporated by reference will survive the entire pendency of this application, including any subsequent continuation, divisional, or continuation-in-part thereof or any reissue or extension.
