Description

Technical Field

[0001] The following description relates to an electric motor for generating torque, particularly for driving an elevator car in an elevator system, the motor including a motor housing and one or more motor components arranged in the motor housing, the one or more motor components being connected to a plurality of first conductors.

[0002] Furthermore, the following description pertains to elevator systems that include such motors. Background Technology

[0003] Electric motors are known in various forms in the prior art and are used to generate torque in a variety of devices. The use of electric motors as drives for elevator cars in elevator systems is also known in the prior art. Elevator systems for the vertical and / or horizontal transport of people and / or goods are an integral part of modern residential and commercial buildings. A typical elevator system has an elevator shaft in which at least one elevator car moves between landings via a drive and a carrying device.

[0004] The application of electric motors typically requires them to be cost-effective and compact. In particular, even in confined spaces, the motors must be easy to install and connect.

[0005] EP 2 033 922 B1 describes a motor for an elevator drive having multiple connection terminals located inside the motor, wherein a cable seal for a cable having multiple conductors is provided in the wall of the motor housing. Summary of the Invention

[0006] Therefore, the object of the present invention is to provide a motor that is inexpensive and requires little installation space.

[0007] This objective is achieved through the features of the independent claim. Advantageous embodiments are defined in the dependent claims. Where technically feasible, the teachings of the dependent claims can be combined with any combination of the teachings of the independent and dependent claims.

[0008] Specifically, this objective is achieved by an electric motor for generating torque, the motor including a motor housing and one or more motor components arranged in the motor housing, a plurality of first conductors connected to the one or more motor components, wherein at least one first wall of the motor housing has at least one through-hole, wherein at least one through-hole terminal is arranged in the at least one through-hole, such that a first connector for connecting the first conductors is arranged inside the motor housing, and a second connector for connecting the second conductors is arranged outside the motor housing, the second connector being electrically connected to the first connector, and wherein each first conductor is connected to a separate through-hole terminal arranged in the through-hole.

[0009] Advantages are explained below and preferred modifications are further described below. The descriptions, particularly regarding the advantages and limitations of the features, are substantially illustrative and preferred, not limiting, examples. Where a description is limiting, it will be explicitly stated.

[0010] When ordinal numbers ("first", "second", etc.) are used, for example to name parts, elements, method steps, or method actions, these ordinal numbers are purely for distinguishing names and do not indicate any dependency or order. This specifically means that a device does not necessarily have a "first part" in order to have a "second part". A device may also have a "first part" and a "third part" without necessarily having a "second part". Multiple units with the same ordinal number may also be provided, for example, multiple "first parts".

[0011] An electric motor is an electromechanical converter, that is, a motor that converts electrical power into mechanical energy. In a conventional electric motor, the conductor coils through which current flows generate a magnetic field, and the mutual attraction and repulsion forces of the magnetic fields are converted into motion. In an electric motor, there exists a stationary stator and a rotating rotor opposite it. One of them has a permanent magnet and the other has an electric coil, or both components have electric coils. Each coil through which current flows generates a magnetic field, the orientation of which depends on the direction of the current. The continuous rotation of the rotor is achieved by continuously switching the direction of the current or changing the polarity of the coils during rotation.

[0012] Motor components specifically refer to the rotor, commutator, or inverter—a disk with electrical connections to which coils are connected and whose polarity changes during one revolution. Motor components can also be power converters, particularly frequency converters. A first conductor is disposed on the aforementioned components, specifically for supplying a phase of power. Furthermore, motor components are particularly control devices, especially control units with data processing devices such as microcontrollers. A first conductor is disposed on such control devices, for example, for transmitting control signals or supplying a phase of power.

[0013] The motor housing is understood as an integral cover that completely or partially surrounds the motor components and isolates them from the environment. The motor housing is specifically formed by multiple walls that are connected to each other and / or attached to the motor components. Furthermore, the motor components themselves may also form parts of the motor housing through their outer surfaces. Through-openings are recesses that penetrate the motor housing, thereby creating a smooth connection between the exterior and interior of the motor housing.

[0014] A conductor is a single, conductive device, and unlike a cable, a conductor forms part of a cable, while a cable typically comprises multiple conductors. According to this understanding, a conductor always provides only a single potential or signal and always has only one direction of conduction at a time. Specifically, a conductor is the wire or strand of a multi-conductor cable.

[0015] A through-terminal is an electronic component having a first connector for receiving a single conductor and a second connector for receiving a single conductor, wherein the through-terminal forms a conductive connection between two received conductors or between two connectors. Through-terminals are well-known as standard components in switchgear constructions and are therefore mass-produced. Accordingly, such through-terminals are correspondingly inexpensive. In particular, through-terminals from switchgear constructions are designed to be clamped onto so-called mounting rails using clamping parts, wherein the mounting rails or clamping devices have or occupy standardized dimensions. However, through-terminals are also known as components independent of switchgear construction and are available at low cost. For example, conductors are connected to the through-terminal by inserting conductors, where insertion can induce locking and contact, or contact is achieved by an operating element.

[0016] For the purposes of this disclosure, all features and aspects explained based on a single through-terminal can be accordingly applied to multiple, and in particular to all through-terminals. Aspects and features described for multiple through-terminals can also be understood, where the context permits, as applicable, to apply to a single through-terminal.

[0017] The solution to the aforementioned motor problem now includes the following teaching: the external connection of the motor is constituted by through-terminals arranged in the motor housing wall, which connect to the power and / or signal conductors during assembly. In this way, the channel for the conductors to pass through the motor housing is formed by low-cost components, and there is no need for other complex and expensive through-terminals, such as dedicated plugs or cable through-terminals, to pass through the motor housing. Furthermore, motor components can be directly connected to the first connector of the through-terminals without further wiring of the conductors within the motor housing. This allows the motor to be designed to be particularly compact. In particular, multiple through-terminals can be independently positioned on the first wall for a particularly compact arrangement. Of course, multiple through-openings can also be formed on different walls of the motor housing, with through-terminals arranged in each through-opening to achieve the shortest possible first conductor and thus a particularly compact motor. Furthermore, by selecting the through-terminals, the connection diagram in the external space can also be adapted to the installation conditions, particularly during installation, the direction of the second conductor connection can be relatively freely adjusted or adapted to the installation conditions, particularly to the available surrounding installation space. Ultimately, the second conductor can be connected to the motor without having to open the motor housing during installation, thus limiting the required installation space for the connection.

[0018] As an alternative to the above features, or in the preferred embodiment described above, the support element is arranged orthogonally to the first wall in at least one through-hole, wherein the through-hole terminal is held on the support element. The support element securely holds the through-hole terminal in the through-hole and is specifically provided with a retaining surface having a wall thickness significantly greater than that of the first wall to hold the through-hole terminal. Specifically, the support element is a separate component from the first wall and is arranged such that the support element and the through-hole terminal are arranged on the motor and connected to each other during factory assembly of the motor before the first wall is installed. For example, the through-hole in the first wall can then be designed such that it can fit over the through-hole terminal already arranged on the support element during the assembly of the first wall. Alternatively, the through-hole terminal can be first attached to the support element and then the through-hole terminal and the support element are arranged as a combination on the first wall.

[0019] In the preferred embodiment described above, the through-terminal is held on the support element in a form-fit manner. The through-terminal can then be attached to the support element particularly easily, and in particular, without tools. It is particularly preferred that the support element is designed such that the through-terminal is first arranged on the support element, and then a form-fit connection is established and / or secured by a subsequently installed first wall, or by arranging the support element and the through-terminal on an already installed first wall.

[0020] For example, the support element and the through-hole terminal arranged thereon are inserted into the through-hole.

[0021] As an alternative to the above features, or in the preferred embodiment described above, the support element is designed with a geometry corresponding to the cross-section of the mounting rail, and the through-terminal is clamped onto the support element. The mounting rail—also known as a DIN rail, or, in the case of a cap-shaped profile, a cap rail—is a general-purpose support made of profiles, such as sheet metal or plastic, and is used in electrical engineering to install electrical equipment in distribution boxes, control cabinets, junction boxes, etc. Various components, such as relays, surge switches, timers, circuit breakers, or terminals, can be pushed onto the side of the mounting rail or inserted from the front and locked in place, particularly by clamping. This standardized approach facilitates the assembly of switchgear and switch boxes. Various types of mounting rails are standardized in the DIN EN 60715:2018-07 standard (Dimensions of low-voltage switchgear—Standardized mounting rails for mechanical fastening of electrical installations in switchgear). Therefore, standard components can be used as through-terminals, having a geometry corresponding to the cross-section of the mounting rail and being particularly cost-effective as mass-produced products. Conversely, by designing the support element with a cross-sectional geometry that has a mounting rail, the fastening geometry of the standard through-terminal is advantageously utilized and used to fasten the through-terminal.

[0022] As an alternative to the above features, or in the preferred embodiment described above, the continuous support elements are arranged orthogonally to the first wall in a plurality of through-holes arranged on the first wall, with through-hole terminals respectively held on the support elements. In embodiments with multiple through-holes, the support elements are easier to handle than multiple support elements for each through-hole, and only one assembly operation is required. In particular, pre-assembly is especially easy in embodiments where the through-hole terminals are first attached to the support elements and then the first wall is assembled or mounted on the first wall. For example, the through-holes can then be sized such that when the first wall is installed after the support elements and through-hole terminals are installed, the through-holes can simultaneously fit over all the through-hole terminals.

[0023] As an alternative to the aforementioned features, or in a preferred embodiment of the design described above, the second connector is aligned parallel to the first wall, allowing the second conductor extending parallel to the first wall to be directly connected to the second connector. The conductor extending parallel to the first wall thus extends straight at and within the second connector without any kinks or bends. The connection of the second conductor is therefore possible in such a way that the connected second conductor occupies minimal installation space near the motor and requires only a small amount of such installation space to connect. In particular, combined with the compact design of the motor itself as described above, this results in a particularly low overall space requirement.

[0024] Furthermore, as an alternative, one embodiment is configured such that the through-terminal has a plurality of, particularly two, second terminals, wherein the plurality of second terminals are oriented in different directions. The plurality of second connectors are then electrically connected to the same first connector or a plurality of identical first connectors. Specifically, the first second connector is aligned parallel to the first wall and the second second connector is aligned orthogonally to the first wall. The motor is then advantageously designed for alternative connection modes or connection scenarios depending on the application.

[0025] Independent of the second connector, the first connector can be aligned parallel, inclined, or orthogonal to the first wall. In particular, the through-terminals can be selected in such a way that the connection from the first conductor to the through-terminal within the motor housing can be designed to be particularly simple and compact for each through-terminal.

[0026] In the preferred embodiment described above, at least one through-terminal is configured to have an operating element for opening and closing the second connector, wherein the operating element is designed to be accessible from a direction parallel to the first wall. The operating element is, in particular, a button on the terminal, such as a plastic snap-fit ​​or a threaded engagement, and is used to lock the conductor connected to the second connector by a retaining device and to make reliable contact therewith, or to make reliable contact with and retain it in place with the conductive portion of the through-terminal. In this respect, the through-terminal can be (briefly) opened using a tool such as a screwdriver to connect the second conductor. As long as the control element is designed to be accessible from a direction parallel to the first wall, the tool can be guided so that its body extends parallel to the first wall. Therefore, the space required for connecting the motor is kept particularly small.

[0027] In another embodiment, the second connector is designed to allow easy insertion of the second conductor; that is, inserting the second conductor opens it and also locks it in the inserted state. This has the advantage that the second conductor can then be inserted particularly easily from the alignment direction of the second connector without tools. The second conductor can also be assembled onto a plug to make connection particularly easy.

[0028] As an alternative to the above features, or in the preferred embodiment described above, the motor further includes a mounting plate held on the outer side of the first wall and having at least one receiving portion for connection to a second conductor of the second connector, the receiving portion being spaced apart from the second connector. The second conductor connected to the second connector is then held and guided at two points, on the one hand by its attachment to the second connector and on the other hand by the second receiving portion, and is thus effectively secured against damage and prevented from detaching from the second connector. Furthermore, a stress-relieving portion can be arranged on the mounting plate, to which the second conductor is additionally held. The receiving portion thus forms a guide and optionally a stress-relieving portion, thereby serving as a guide and protection for the second conductor. In particular, multiple second conductors can be combined in a cable associated with a single receiving portion.

[0029] Furthermore, the mounting plate preferably has multiple mounting portions, particularly arranged on different sides. For example, the mounting plate has one or more flanges, each flange projecting vertically from the first wall, and mounting portions or multiple mounting portions are arranged in the flanges for mounting a second conductor extending parallel to the first wall.

[0030] One or more receiving portions of the mounting plate preferably have retaining elements, particularly retaining elements made of rubber, through which the second conductor or a cable comprising multiple second conductors is held and further protected from direct contact with the metal sheet material of the mounting plate. The mounting plate is made of, for example, metal or plastic material.

[0031] As an alternative to the above features, or in the preferred embodiment described above, the mounting plate is provided with at least one additional through-hole for one or more through-terminals. The mounting plate can then be held against the first wall by surrounding one or more through-terminals, such that a particularly large area in the first wall can be provided for holding the mounting plate, and that a receiving portion for the second conductor can be provided on the mounting plate (e.g., at the corresponding bend) spanning the entire area of ​​the first wall. In particular, the one or more additional through-holes are designed so that the mounting plate can be fitted over one or more through-terminals through these through-holes, thereby allowing the mounting plate to be installed particularly easily on the first wall even after the through-terminals and any supports have been installed.

[0032] As an alternative to the above features, or in the preferred embodiment described above, the first wall and / or mounting plate surrounds and abuts against at least one through-terminal. Subsequently, the through-terminal (particularly via the first wall or mounting plate) is held in the through-opening in a form-fitting manner, and the first wall or mounting plate and the through-terminal form a substantially closed enclosure structure for the motor outwards. The sealing function of the motor housing is thus maintained by utilizing the through-opening and the through-terminal disposed therein.

[0033] As an alternative to the above features, or in the preferred embodiment described above, a sealing element is arranged between the first wall or receiving plate and the through-terminal in at least one through-opening and / or at least one additional through-opening. Thus, the sealing function of the motor housing is maintained by utilizing the through-opening or additional through-opening and the through-terminal arranged therein, and undesirable substances such as foreign objects, dirt, dust, and liquids are prevented from entering through the through-opening.

[0034] As an alternative to the above features, or in the preferred embodiment described above, at least one first conductor forms a phase of the power supply to the motor component, at least one first conductor forms a protective conductor of the power supply to the motor component, and / or at least one first conductor is configured for conducting control signals. These types of conductors represent types of conductors that are typically guided through the motor housing and connected externally to the motor. Particularly preferred is that all conductors of the motor component present in the motor pass through the wall of the motor housing via through-terminals as described above.

[0035] This objective is further achieved by an elevator system comprising: at least one elevator shaft, at least one elevator car capable of moving along the elevator shaft, and at least one drive designed to power a motor as described above, wherein the elevator car can be driven by the drive via a carrying device.

[0036] An elevator shaft is a continuous shaft that spans multiple floors or extends along multiple areas of a building and has a cross-section designed for the passage of elevator cars. Elevator shafts in elevator systems can extend vertically and / or horizontally, with motors used for the drive, particularly in elevator systems with vertical shafts.

[0037] The load-bearing device is specifically designed as a rope, belt, chain, etc., and bears tensile loads in its longitudinal direction. Particularly preferred is that the load-bearing device is held, guided, and driven by friction and optionally braked by a brake on the drive pulley, in cooperation with a drive wheel.

[0038] The above-mentioned solutions to the problems of elevator systems now include the following teachings: the drive is designed as the aforementioned motor, and thus the aforementioned advantages are accordingly incorporated into the elevator system. The elevator system is therefore highly cost-effective and compact, and the available installation space in the elevator system is utilized in an advantageous and installation-friendly manner.

[0039] In the preferred embodiment described above, the motor is arranged in the head of the elevator shaft. The head of the shaft is understood as the end portion of the internal space of the shaft. In a vertical elevator shaft, the head of the shaft is formed specifically at the upper end of the elevator shaft and, for example, opposite to the shaft pit formed at the lower end. By arranging the drive in the head of the shaft, a separate machine room located externally, particularly above the elevator shaft, can be eliminated, and the elevator system can be designed to be particularly compact. Thus, the building on which the elevator system is located does not need to include a floor or superstructure above the top floor served by the elevator system for a machine room. In other words, the elevator system can conveniently serve the building up to its highest point without the need for a superstructure on the building. The above advantages are particularly significant when the drive is located in the head of the shaft, because the available installation space in the head of the shaft is usually particularly limited. Conversely, the compact design of the motor allows it to be arranged in the head of the shaft.

[0040] In the preferred embodiment described above, the motor is arranged opposite a first wall of the elevator shaft. Then, if one or more second connectors are aligned parallel to the first wall, the second conductor can still be connected to one or more through-terminals. The motor can then be advantageously arranged in the shaft head, and subsequent connections can be made easily and reliably despite limited available installation space. Attached Figure Description

[0041] The preferred technical solutions will be explained in more detail below with reference to the accompanying drawings, based on preferred embodiments. The term "drawings" is abbreviated as "Figures" in the drawings.

Each feature described for a particular exemplary embodiment can be used independently or in combination with other features in any other embodiment. Each feature described for an exemplary embodiment of a particular claim class can also be applied accordingly to exemplary embodiments of another claim class.

[0044] Figure 1 An electric motor 1 is shown, having a motor housing 2, wherein a first wall 2.1 on the head side of the motor housing 2 is shown transparently, and this first wall 2.1 is connected to the rest of the motor housing 2 via a threaded connection 3. Inside the motor 1, there are a first motor component 4.1 designed as a rotor and a second motor component 4.2 designed as a stator, the first motor component 4.1 and the second motor component 4.2 having a first conductor for energy supply and / or control, the first conductor in… Figure 1 The details are not shown. The first wall 2.1 has a first through-opening 5.1 and a second through-opening 5.2. Four through-terminals 6.1, 6.2, 6.3, and 6.4 are arranged in the first through-opening 5.1, and two through-terminals 6.5 and 6.6 are arranged in the second through-opening. The first wall 2.1 is placed against the through-terminals 6.1, ..., 6.6, and the through-openings 5.1 and 5.2 are completely filled by the through-terminals 6.1, ..., 6.6 so that the motor housing 2 is substantially closed. In addition, although not shown in detail, additional through-openings in which the through-terminals are arranged can also be provided on other walls of the motor housing 2.

[0045] Figure 2 Show in detail according to Figure 1The motor 1 is cut away in the area surrounding the through terminals 6.1, ..., 6.6. The through terminals 6.1, ..., 6.6 are designed as standard terminals for a switch box construction and are each held on a support element 7, which is arranged orthogonally to the first wall 2.1. The support element 7 has a geometry corresponding to the cross-section of the mounting rail and a web 7.1, such that the support element 7 extends across two through openings 5.1, 5.2. The through terminals 6.1, ..., 6.6 are clamped to the support element 7 by means of snaps, which also allow them to be clamped to the mounting rail of the switch box. Inside the motor housing 2, the through terminals 6.1, ..., 6.6 have first connectors 8.1, and first conductors 9.1, 9.2, 9.3, 9.4 are each connected to and clamped to each first connector 8.1. The first conductors 9.1, ..., 9.4 are specifically wired to the power supply; the first conductor 9.1 here is a grounding conductor for grounding the first wall 2.1, while conductors 9.2, 9.3, and 9.4 are phase or protective conductors of the power supply. Outside the motor housing 2, through terminals 6.1, ..., 6.6 have second connectors 8.2, and each of the second conductors 10 is connected to each second connector 8.2 and is specifically clamped. The second conductors 10 are bundled together in the cable 11 and thus... Figure 2 The second conductor 10 is not clearly seen. In terms of its wiring, the second conductor 10 corresponds to the first conductors 9.1, ..., 9.4, and each of the second conductors 10 is connected to the first conductors 9.1, ..., 9.4 via through terminals 6.1, ..., 6.6.

[0046] As in Figure 2 As further shown, the second connector 8.2 is arranged on the through terminals 6.1, ..., 6.6 so that they are aligned parallel to the first wall 2.1. The second conductor 10 of the cable 11, which extends parallel to the first wall 2.1, can therefore be directly connected to the second connector 8.2, and the cable 11 does not need to have any kinks or bends for connection.

[0047] Figure 3 Motor 1 is shown, which is similar in basic characteristics to that in Figure 1 and Figure 2 The motor 1 shown is not described again, and the motor 1 also has a mounting plate 12, which is held against the first wall 2.1. Figure 3In the exploded view, the first wall 2.1 and the mounting plate 12 are shown as spaced apart from each other. The mounting plate 12 is, for example, glued, threaded, or bonded to the first wall 2.1. The mounting plate 12 has a base 12.1 that rests against the first wall 2.1, and the base 12.1 has a first additional through opening 13.1 and a second additional through opening 13.2. The first additional through opening 13.1 is for arranging around four through terminals 6.1, 6.2, 6.3, and 6.4, and the second additional through opening 13.2 is for arranging around two through terminals 6.5 and 6.6. The additional through openings 13.1, 13.2 correspond, for example, to through openings 5.1, 5.2, and the additional through openings 13.1, 13.2 are arranged to align with these through openings around the through terminals 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, wherein, for example, through openings 5.1, 5.2, 13.1, 13.2 are pushed above the through terminals 6.1, 6.2, 6.3, 6.4, 6.5, 6.6 after they have been mounted on the support element 7 during the assembly of the motor 1. The base 12.1 is then placed completely against the first wall 2.1.

[0048] Mounting plate 12 also has bends 12.2 and 12.3, which are perpendicular to base 12.1 and first wall 2.1, respectively, and have receiving portions 15.1, 15.2, 15.3, and 15.4 formed as through holes. Holding elements 16.1, 16.2, 16.3, and 16.4 are arranged in the receiving portions 15.1, 15.2, 15.3, and 15.4, through which the second conductor 10 or cable 11 can be received and guided. Figure 3 Not shown in detail, the second conductor 10 or cable 11 is spaced apart from the through terminals 6.1, 6.2, 6.3, 6.4, 6.5, and 6.6. The retaining elements 16.1, 16.2, 16.3, and 16.4 are designed as rubber covers and therefore, in addition to their retaining function for the second conductor 10 or for the cable 11, also cover the receiving portions 15.1, 15.2, 15.3, and 15.4. The receiving portions 15.1, 15.2, 15.3, and 15.4 with the retaining elements 16.1, 16.2, 16.3, and 16.4 allow the second conductor 10 or cable 11 to be arranged in an orderly manner in the area in front of the first wall 2.1. A strain relief portion 17 for receiving the second conductor 10 or cable 11 guided through the first receiving portion 15.1 and means for additional strain relief portions 17 are also arranged at the base 12.1.

[0049] Figure 4A simplified diagram of an elevator system 20 is shown, which has an elevator shaft 21 and a car 22 capable of traveling within the elevator shaft 21. The elevator car 22 has elevator car doors 23 that can form passageways with multiple landing doors 24.1, 24.2, 24.3, and 24.4 at corresponding stopping positions. In a highly simplified manner, the elevator car 22 is suspended relative to a counterweight 27 by a support device 26, which is guided by a guide device 25. The support device 26 can also be driven by a drive wheel 28, the necessary driving torque being provided by a motor 2 connected to the drive wheel 28. The motor 2 is located in the shaft head 21.1 of the elevator shaft 21 and is arranged such that a first wall 2.1 directly abuts against the shaft wall 21.2.
