In these motors, the relative positions of the stator and rotor are fixed and cannot be adjusted or moved to adapt to changing demands. Therefore, these motors may not meet the specific operational requirements of certain applications. For example, in some complex mechanical systems, it may be necessary to adjust the rotor position to achieve different functions or optimize system performance.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0043] To address the shortcomings of existing technologies, this invention provides a motor device with two stators. By controlling the working states of stators A and B, the rotor can move in three different rotational working positions to meet different working requirements and improve the flexibility and applicability of the motor.

[0044] In the embodiments of this application, the movement of the rotor at different positions, combined with different energizing types, gives rise to a variety of rotor motion modes, which can improve working performance, reduce manufacturing costs, and increase stability.

[0045] Specifically, the structural innovation lies at least in the flexible selection of the stator and its combination with the rotor: the dual-stator structure allows for the integration of different types of stators within the same motor. These stators can have different winding designs, material properties, or magnetic circuit configurations. This design flexibility allows the motor to select the optimal stator combination according to the specific application requirements, thereby optimizing the motor's performance.

[0046] In one embodiment, see Figure 1 To enable lateral movement of the rotor and multiple rotational operating positions by controlling the stator's operating state, this application provides a multi-condition motor, including: a rotor 1, a first stator A, a second stator B, and a controller (which may, but is not limited to, be mounted on the rotor 1) electrically connected to the rotor, the first stator, and the second stator; wherein, the first stator A and the second stator B are both mounted on the rotor 1; the first stator A is positioned at a first position, the second stator B is positioned at a third position, and there is a gap between the first stator A and the second stator B, the gap being located at a second position; the rotor 1 moves axially under the control of the controller to achieve DC switching mode operation, single-phase AC pulsation mode operation, and three-phase AC rotational motion mode operation. Magnets are fixedly mounted on the rotor 1 for electromagnetic induction with the first stator A and / or the second stator B to achieve axial movement of the rotor 1.

[0047] The structure conforms to the basic structure of an electric motor: the stator is made of stacked silicon steel sheets with slots, and the stator windings are embedded in the slots.

[0048] Understandably, see Figure 2 , Figure 3 As shown, this embodiment employs a dual-stator structure, with stator A and stator B installed at different positions on rotor 1. Magnets 2 are mounted on rotor 1, and rotor 1 can be axially reset to its initial position using a series of forces such as magnetic force, spring force, or gravity. The initial position can be as follows: Figure 2 Set or coincide with position 1 (also known as the first position). See the cross-sectional view of position 1. Figure 3 As shown, a common permanent magnet synchronous motor structure is used. The cross-sectional view of position 3 (also known as the third position) is the same as that of position 1. However, since the stator B is far from the initial position, it is necessary to appropriately increase the number of turns or the thickness of the coil. Essentially, this can be understood as changing the position of motion through electromagnetic force. Increasing the electromagnetic force can be achieved by increasing the number of turns or the thickness of the coil.

[0049] Specifically, the multi-condition motor in this application embodiment includes the following components:

[0050] Rotor Shaft (also called rotor): Designed as a shaft capable of moving laterally, it is installed between stator A and stator B.

[0051] Stator A and Stator B: Installed at different positions on the rotor shaft, stator A and stator B can work independently or simultaneously to generate an electromagnetic field to control the position of the rotor shaft.

[0052] Magnet: A magnet mounted on the rotor shaft. When the stator is working, it interacts with the stator's magnetic field to adjust the rotor shaft position. This motor is mainly a permanent magnet synchronous motor with a surface-mounted permanent magnet structure. The magnet 2 is fixed by adsorption onto a magnetic material.

[0053] Controller: Used to control the working state of stator A and stator B, and to switch the position of the rotor shaft as needed.

[0054] Functions and interrelationships of each component

[0055] Rotor Shaft: As the moving part, it moves laterally through the interaction of the electromagnetic field between the magnet 2 and the stator.

[0056] Stator A and Stator B: These generate an electromagnetic field to control the position of the rotor shaft. Stator A and Stator B attract and position the magnet 2 through the electromagnetic field.

[0057] Magnets interact with the electromagnetic field of the stator to adjust the position of the rotor shaft.

[0058] Controller: Controls the working state of stator A and stator B, and switches the position of the rotor shaft as needed to achieve different working modes.

[0059] As can be seen from the above description, the multi-condition motor provided in this application can realize the movement of the rotor in three different rotating working positions by controlling the working states of stator A and stator B, thus solving the problem that existing motors cannot dynamically adjust the rotor position to adapt to different working requirements.

[0060] In one embodiment, see Figure 4 In order to achieve lateral movement of the rotor and have multiple rotational working positions by controlling the working state of the stator, this application provides a control method for a multi-condition motor, applied to the multi-condition motor, including:

[0061] S101: Receive operating condition commands from the host computer; wherein, the operating condition commands include DC power switching mode operating condition commands, single-phase AC power pulsation mode operating condition commands, and three-phase AC power rotational motion mode operating condition commands.

[0062] S102: When the DC power switching mode operation command is received, DC power is supplied to the first stator and / or the second stator to realize the DC power switching mode operation.

[0063] S103: When the pulse mode operating condition command of the single-phase AC power is received, single-phase AC power is supplied to the first stator and / or the second stator to realize the pulse mode operating condition of the single-phase AC power.

[0064] S104: When the three-phase AC rotation mode operating condition command is received, three-phase AC power is supplied to the first stator and / or the second stator to realize the three-phase AC rotation mode operating condition.

[0065] Understandably, this motor assembly can be categorized into three control modes based on the type of current flowing through the stator: 1. DC switching mode; 2. Single-phase AC pulsation mode; 3. Three-phase AC rotation mode. The motion modes under these three control modes are described in detail below:

[0066] Specifically, see Figure 5 Step S101: The step of applying DC current to the first stator and / or the second stator to achieve the DC current switching mode operation includes:

[0067] S201: Only direct current is supplied to the first stator, so that the rotor is subjected to the axial electromagnetic force of the first stator, moving from the initial position to the first position without axial rotation; or

[0068] S202: Simultaneously apply direct current to the first stator and the second stator, so that the rotor is subjected to the common axial electromagnetic force of the first stator and the second stator, moving from the initial position to the second position; or

[0069] S203: Apply DC current only to the second stator so that the rotor is subjected to the axial electromagnetic force of the second stator and moves from the initial position to the third position.

[0070] The reset process can be achieved in the following ways.

[0071] ①Magnetic reset:

[0072] Principle: It utilizes the interaction between the magnet 2 and the fixed magnet (or electromagnet) generated by magnetic force.

[0073] Operating principle: When the magnet 2 on the rotor shaft approaches the fixed magnet, the magnetic force attracts or pushes the magnet 2 away from the rotor shaft, causing the rotor shaft to stop stably at a predetermined position. This method is typically used in applications requiring non-contact and precise position control.

[0074] ② Spring force reset:

[0075] Principle: Utilizing the elastic force of a spring.

[0076] Operating principle: A spring is installed on the rotor shaft. When magnet 2 approaches the target position, the spring deforms under force, generating a restoring force that pushes magnet 2 on the rotor shaft to the predetermined position. This method is usually used in conjunction with a mechanical position sensor or limit switch and is suitable for position control applications requiring significant force.

[0077] ③ Gravity reset:

[0078] Principle: Utilizing the force generated by gravity.

[0079] Operating principle: Gravity is used as the restoring force in the vertical direction. When magnet 2 is in a state where no external force is applied, gravity pulls magnet 2 on the rotor shaft to a predetermined downward position. This method is commonly used for vertical position control, such as vertical door or valve control.

[0080] Understandably, the switching mode of DC power requires the rotor to be energized with DC. Energizing with DC power enables linear motion of the rotor, which is applied in fields such as machining.

[0081] 1. Stator A is energized with DC current, while stator B is not energized.

[0082] At this time, the rotor is subjected to the axial electromagnetic force given by the stator A, and moves from the initial position to position 1, without axial rotational motion;

[0083] 2. Stator A and B are simultaneously energized with DC current.

[0084] At this moment, the rotor is subjected to the axial electromagnetic force from stators A and B together, and moves from the initial position to position 2;

[0085] 3. Stator B is energized with DC current, while stator A is not energized.

[0086] At this moment, the rotor receives the axial electromagnetic force from the stator B and moves from the initial position to position 3.

[0087] Specifically, see Figure 6 In step S102: the step of supplying single-phase alternating current to the first stator and / or the second stator to achieve the pulse mode operation of single-phase alternating current includes:

[0088] S301: A single-phase alternating current of a first current intensity is supplied only to the first stator, so that the rotor is subjected to a periodic axial electromagnetic force, causing it to reciprocate between the initial position and the first position; or

[0089] S302: Single-phase alternating current with a phase difference of 180° is applied to the first stator and the second stator respectively, so that the rotor is subjected to periodic axial electromagnetic force and reciprocates between the first position and the third position; or

[0090] S303: A single-phase alternating current of a second current intensity is supplied only to the second stator to subject the rotor to a periodic axial electromagnetic force, so that the rotor reciprocates between an initial position and a third position; wherein the second current intensity is greater than the first current intensity.

[0091] Understandably, achieving the pulse mode operation of single-phase AC requires the stator to be powered by single-phase AC.

[0092] The reciprocating motion of a rotor has various applications in the engineering field, mainly in the following aspects:

[0093] ① Compressor and pump applications:

[0094] In some compressors and pumps, the reciprocating motion of the rotor can be used to compress and transport gases or liquids. For example, piston compressors and piston pumps utilize the reciprocating motion of the rotor to compress and pump media.

[0095] ② Certain types of engines:

[0096] In internal combustion engines and some external combustion engines, such as certain steam engines, the reciprocating motion of the rotor is used to drive the piston or plunger, thereby driving the engine. This application is common in automobile engines, diesel engines, and some industrial gas engines.

[0097] ③ Linear motors and linear generators:

[0098] The reciprocating motion of a rotor can be used to drive linear motors or linear generators, which generate power or electrical energy through linear motion rather than rotation. Linear electromagnetic motors have unique applications in situations requiring linear motion.

[0099] ④ Certain special mechanical transmission systems:

[0100] In some mechanical transmission systems that require complex motion trajectories, the reciprocating motion of the rotor can be used to achieve specific motion requirements. This application is common in complex automated devices, specialized manufacturing machinery, and other fields.

[0101] 1. Stator A is powered by single-phase AC, while stator B is not powered.

[0102] When stator A is energized with single-phase alternating current, the rotor will receive a periodic axial electromagnetic force and begin to reciprocate between the initial position and position 1. The strength and frequency of the motion are related to the magnitude and frequency of the stator current.

[0103] 2. Stator A and B are supplied with single-phase alternating current with a phase difference of 180°.

[0104] When the single-phase alternating currents of stators A and B are 180° out of phase, the rotor will be periodically subjected to axial electromagnetic forces from stators A and B, and will reciprocate between position 1 and position 3.

[0105] 3. Stator B is energized with single-phase AC power, while stator A is not energized.

[0106] At this time, the rotor will be periodically subjected to the electromagnetic force of stator B. Since stator B is far from the initial position, the current of stator B should be greater than the current when stator A works alone in this working mode in order to ensure that the rotor reciprocates between the initial position and position 3.

[0107] Specifically, see Figure 7 Step S103: The step of supplying three-phase alternating current to the first stator and / or the second stator to achieve the three-phase alternating current rotational motion mode includes:

[0108] S401: Only three-phase alternating current is supplied to the first stator, so that the rotor is moved to the first position by axial electromagnetic force and moves synchronously with the rotating magnetic field of the first stator under the action of the rotating magnetic field of the first stator; or

[0109] S402: Simultaneously apply three-phase alternating current to the first stator and the second stator, causing the rotor to move to the second position under axial electromagnetic force and move synchronously with the stator magnetic field (also called the rotating magnetic field) under the action of the rotating magnetic field; or

[0110] S403: Only three-phase alternating current is supplied to the second stator to make the rotor move to the third position and rotate under the action of the rotating magnetic field of the second stator.

[0111] Understandably, achieving a rotating motion mode with three-phase alternating current requires supplying three-phase alternating current to the rotor. Rotational motion of the rotor is the most common form of motor motion, used in automotive new energy motors, wind turbines, and other applications.

[0112] 1. Stator A is powered by three-phase AC power alone.

[0113] At this time, the rotor is moved to position 1 by the axial electromagnetic force. Since the stator A is supplied with three-phase alternating current, a rotating magnetic field is generated. The rotor moves synchronously with the rotating magnetic field under the action of the rotating magnetic field.

[0114] 2. Stator A and B are simultaneously energized with three-phase alternating current.

[0115] At this time, the rotor is subjected to the axial electromagnetic force of stators A and B, moves to position 2, and moves synchronously with the stator magnetic field under the action of the rotating magnetic field.

[0116] 3. Stator B is powered by three-phase AC power alone.

[0117] At this point, the rotor moves to position 3 and rotates under the influence of the rotating magnetic field of stator B.

[0118] In summary, the present invention demonstrates its beneficial effects in several aspects:

[0119] ① Improved performance: By employing three different control methods, the most suitable control mode can be selected for specific application requirements. The DC switching mode, the single-phase AC pulsation mode, and the three-phase AC rotary motion mode give the motor assembly wide adaptability and high efficiency. In other words, it provides a multi-functional motion mode selection, enabling it to perform excellently in different working environments.

[0120] ② Reduced manufacturing costs: By integrating multiple control methods into the design, the need for motors specifically designed for different purposes can be reduced, thereby lowering production and maintenance costs. In other words, a unified design makes mass production more economical and helps reduce the manufacturing cost of individual motors.

[0121] ③ Reduced energy loss: The rotor's different positional movements are achieved through precisely controlled stator energization, effectively reducing unnecessary energy loss and improving the motor's overall energy efficiency. Selecting the most suitable control mode for specific needs avoids excessive energy consumption.

[0122] ④ Increased stability: By simultaneously energizing multiple stators, more balanced and stable rotation or linear motion can be achieved, reducing vibration and instability. The application of multiple control methods improves the motor's adaptability and stability in extreme working environments.

[0123] ⑤ Ease of operation, control, and use: User-friendliness is considered; different control methods can be achieved through simple circuit switching, eliminating the need for complex operating procedures. Users only need basic power-on control knowledge to realize various motor motion modes, greatly simplifying operation.

[0124] ⑥ Other useful features: By integrating multiple control functions, it can be used in situations requiring precise positioning, variable speed, and various dynamic controls, such as in robotics and automated production lines, achieving highly flexible and efficient applications. The unified motor component design also facilitates modular maintenance and replacement; when a fault occurs, only the corresponding module needs to be replaced, simplifying the maintenance process and improving the overall system reliability.

[0125] Overall, this invention, through the integration of multiple control methods, greatly improves the performance, operational flexibility, and cost-effectiveness of the motor system, giving it significant advantages in multiple application areas.

[0126] Based on the same inventive concept, this application also provides a control device for a multi-condition motor, which can be used to implement the methods described in the above embodiments, as described in the following embodiments. Since the principle of solving the problem with a multi-condition motor and its control device is similar to that of a multi-condition motor and its control method, the implementation of a multi-condition motor and its control device can refer to the implementation of the method based on software performance benchmarks; repeated details will not be elaborated further. As used below, the terms "unit" or "module" can refer to a combination of software and / or hardware that implements a predetermined function. Although the system described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0127] In one embodiment, see Figure 8 In order to achieve lateral movement of the rotor by controlling the working state of the stator and to have multiple rotational working positions, this application provides a control device for a multi-condition motor, including:

[0128] The operating condition command receiving unit 801 is used to receive operating condition commands from the host computer; wherein, the operating condition commands include DC power switching mode operating condition commands, single-phase AC power pulsation mode operating condition commands, and three-phase AC power rotational motion mode operating condition commands.

[0129] The DC control unit 802 is used to supply DC power to the first stator and / or the second stator when it receives the DC power switching mode operation command, so as to realize the DC power switching mode operation.

[0130] The pulse control unit 803 is used to supply single-phase AC power to the first stator and / or the second stator when it receives the pulse mode operating condition command of the single-phase AC power, so as to realize the pulse mode operating condition of the single-phase AC power.

[0131] The rotation control unit 804 is used to supply three-phase AC power to the first stator and / or the second stator when it receives the three-phase AC power rotation motion mode operation command, so as to realize the three-phase AC power rotation motion mode operation.

[0132] From a hardware perspective, in order to achieve lateral movement of the rotor and have multiple rotational working positions by controlling the operating state of the stator, this application provides an embodiment of an electronic device for implementing all or part of the aforementioned multi-condition motor and its control method. The electronic device specifically includes the following components:

The specific choice depends on the processing power of the client device and the limitations of the user's usage scenario. This application does not impose any limitations on this. If all operations are completed in the client device, the client device may further include a processor.

[0136] The aforementioned client device may have a communication module (i.e., a communication unit) that can communicate with a remote server to achieve data transmission. The server may include a server on the task scheduling center side; in other implementation scenarios, it may also include a server on an intermediate platform, such as a server on a third-party server platform that has a communication link with the task scheduling center server. The server may include a single computer device, a server cluster consisting of multiple servers, or a distributed server structure.

[0137] Figure 9 This is a schematic block diagram illustrating the system configuration of the electronic device 9600 according to an embodiment of this application. Figure 9 As shown, the electronic device 9600 may include a central processing unit 9100 and a memory 9140; the memory 9140 is coupled to the central processing unit 9100. It is worth noting that... Figure 9 This is an example; other types of structures can also be used to supplement or replace this structure to achieve telecommunications functions or other functions.

[0138] In one embodiment, the functions of the multi-condition motor and its control method can be integrated into the central processing unit 9100.

[0139] The central processing unit 9100 can be configured to perform the following controls:

[0140] S101: Receive operating condition commands from the host computer; wherein, the operating condition commands include DC power switching mode operating condition commands, single-phase AC power pulsation mode operating condition commands, and three-phase AC power rotational motion mode operating condition commands.

[0141] S102: When the DC power switching mode operation command is received, DC power is supplied to the first stator and / or the second stator to realize the DC power switching mode operation.
