The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0035] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of the present application, a motor assembly is provided, including a motor 30 and a mounting assembly for mounting the motor 30 on a load-bearing body 40, wherein the mounting assembly includes a first action member, which is disposed on one of the motor 30 or the load-bearing body 40 and is controlled to generate a first action force that drives the motor 30 to be suspended and connected to the load-bearing body 40.

[0036] In actual operation, when the motor 30 starts to run, the first action force generated by the first action member causes the motor 30 to be suspended and connected to the load-bearing body 40. At this time, the motor 30 is not directly connected to the load-bearing body 40, and the vibration generated by the motor 30 during operation will not be transmitted to the load-bearing body 40, thereby avoiding resonance between the load-bearing body 40 and the motor 30. In this way, the noise generated by the motor 30 during operation is greatly reduced.

[0037] Compared with the prior art, the motor 30 and the load-bearing body 40 can be suspended and connected so that the vibration generated by the motor 30 during operation cannot be transmitted to the load-bearing body 40, thereby avoiding the noise caused by the resonance between the motor 30 and the load-bearing body 40 and greatly improving the comfort of the user.

[0038] The load-bearing body 40 may be the ground, a wall, or a unit of a ceiling machine.

[0039] In some embodiments, the first action member is used to provide a suspension signal and / or suspension medium to one of the motor 30 and the load-bearing body 40, which enables the motor 30 to be suspended and connected to the load-bearing body 40. The suspension signal can be an electromagnetic signal, a permanent magnetic signal or a high-frequency sound signal, and the motor 30 is magnetically suspended and connected to the load-bearing body 40 under the action of the magnetic force generated by the electromagnetic signal or the permanent magnetic signal, and the motor 30 is acoustically suspended and connected to the load-bearing body 40 under the action of the high-frequency sound signal. The suspension medium can be suspended particles or air (refer to gas suspension technology and particle beam suspension technology), and the suspension medium can make the motor 30 suspended and connected to the load-bearing body 40 when flowing at high speed.

[0040] In some embodiments, see Figure 3The first action member includes a first magnetic part 13 and a second magnetic part 22. The first magnetic part 13 is disposed on the motor 30, and the second magnetic part 22 is disposed on the load-bearing body 40. At least one of the first magnetic part 13 and the second magnetic part 22 includes an electromagnet. When the first magnetic part 13 and / or the second magnetic part 22 is energized, a first repulsive force can be generated between the first magnetic part 13 and the second magnetic part 22, so that the motor 30 is suspended and connected to the load-bearing body 40.

[0041] It can be understood that the first magnetic part 13 and the second magnetic part 22 can both be electromagnets. When both are powered on, magnetic poles can be formed at both ends of each electromagnet, and the first repulsive force can be generated by making the same magnetic poles of the first magnetic part 13 and the second magnetic part 22 face each other. Alternatively, one of the first magnetic part 13 and the second magnetic part 22 is an electromagnet and the other is a permanent magnet. After the electromagnet is powered on, magnetic poles are formed at both ends, and the first repulsive force can be generated when the same magnetic poles are arranged relative to the permanent magnet.

[0042] At this time, the two magnetic parts generate a first repulsive force that enables the motor 30 to be suspended and connected to the load-bearing body 40, which is convenient for simplifying the structure of the motor assembly and reducing costs compared to other suspension technologies (such as airflow suspension technology). At least one electromagnet in the two magnetic parts can control the magnitude of the repulsive force generated by the two magnetic parts by connecting the current magnitude of the electromagnet, which is convenient for controlling the suspension height of the motor 30.

[0043] It is understandable that when the first magnetic part 13 and the second magnetic part 22 are not powered, the motor 30 is directly supported on the load-bearing body 40 under its own gravity. In addition, when the first magnetic part 13 or the second magnetic part 22 is a permanent magnet, it is not powered.

[0044] It should be noted that the embodiment of the present application does not exclude the situation that both the first magnetic part 13 and the second magnetic part 22 are permanent magnets.

[0045] Furthermore, the first magnetic part 13 and the second magnetic part 22 are evenly arranged around the central axis of the motor 30. At this time, one first magnetic part 13 cooperates with one second magnetic part 22 to generate a repulsive force, and multiple first magnetic parts 13 and multiple second magnetic parts 22 are arranged one by one to generate multiple repulsive forces, each of which acts on multiple positions of the motor 30 or the load-bearing body 40, so that the motor 30 can be more stable when suspended.

[0046] In one embodiment, see Figure 1 , Figure 2 and Figure 3The mounting assembly also includes a mounting foot 10, which is fixed to the motor 30 and movably connected to the load-bearing body 40. The first magnetic portion 13 is arranged on the mounting foot 10. When the first magnetic portion 13 and / or the second magnetic portion 22 are energized, a first repulsive force can be generated to cause the mounting foot 10 to be suspended and connected to the load-bearing body 40.

[0047] At this time, the motor 30 is movably connected to the load-bearing body 40 through the mounting foot 10. When the first magnetic part 13 and / or the second magnetic part 22 are energized, the first repulsive force generated between the first magnetic part 13 and the second magnetic part 22 repels the mounting foot 10 from the load-bearing body 40, so that the mounting foot 10 is suspended, and then the motor 30 is suspended. In this way, only a mounting foot 10 needs to be provided on the motor 30, and there is no need to improve the structure of the motor 30 itself. Only the mounting foot 10 needs to be structurally designed to connect the motor 30 and the load-bearing body 40, which helps to reduce development costs.

[0048] There is no limitation on the way in which the mounting foot 10 and the load-bearing body 40 can be movably connected, as long as the mounting foot 10 can connect the load-bearing body 40 and the motor 30, and the mounting foot 10 can have a suspension space relative to the load-bearing body 40. Optionally, a groove is provided on the load-bearing body 40, and the mounting foot 10 can be movably connected in the groove. When the first magnetic part 13 and / or the second magnetic part 22 are powered on, the mounting foot 10 is suspended in the groove so that the motor 30 is suspended. When the first magnetic part 13 and the second magnetic part 22 are powered off, the mounting foot 10 falls into the groove to connect the motor 30 and the load-bearing body 40, so that the motor 30 is supported on the load-bearing body 40. Of course, the schemes in the following embodiments can also be adopted.

[0049] In the specific embodiment, see Figure 3 and Figure 4 The mounting assembly also includes a mounting column 20 for movably connecting the mounting foot 10. The mounting column 20 is configured on the load-bearing body 40. The second magnetic part 22 is configured with the mounting column 20. When the first magnetic part 13 and / or the second magnetic part 22 are energized, a first repulsive force can be generated to cause the mounting foot 10 to be suspended and connected to the mounting column 20.

[0050] At this time, when the first magnetic part 13 and / or the second magnetic part 22 are powered on, the first repulsive force generated by the first magnetic part 13 and the second magnetic part 22 causes the mounting foot 10 to be suspended and connected to the mounting column 20, thereby causing the motor 30 to be suspended relative to the load-bearing body 40. When the first magnetic part 13 and the second magnetic part 22 are not powered on, the mounting foot 10 is directly supported on the mounting column 20, so that the motor 30 is supported on the load-bearing body 40. In this way, by configuring the mounting column 20 on the load-bearing body 40 and setting the mounting foot 10 and the mounting column 20 to be movably connected, there is no need to provide structures such as the above-mentioned grooves on the load-bearing body 40, so that the motor assembly can be applied to various load-bearing bodies 40.

[0051] Specifically in the embodiment, see Figure 3 One of the mounting foot 10 and the mounting column 20 has a mounting hole 11 that penetrates along its own axial direction and a support end 12 that is penetrated by the mounting hole 11, and the other has a rod portion that can be movably inserted into the mounting hole 11, and the rod portion has a first end and a second end that are oppositely arranged along its own axial direction, and a limiting portion 21 is arranged at the second end, and the mounting hole 11 is located between the limiting portion 21 and the first end. When the first magnetic portion 13 and / or the second magnetic portion 22 are energized, a first repulsive force that separates the support end 12 from the limiting portion 21 can be generated.

[0052] In actual operation, when the first magnetic part 13 and / or the second magnetic part 22 are powered, the first repulsive force generated by the first magnetic part 13 and the second magnetic part 22 causes the support end 12 to separate from the limiting part 21, thereby causing the mounting foot 10 to be suspended and connected to the mounting column 20, and causing the motor 30 to be suspended and connected to the load-bearing body 40. When the first magnetic part 13 and the second magnetic part 22 are not powered, the support end 12 is supported on the limiting part 21, causing the mounting foot 10 to be directly connected to the mounting column 20, thereby causing the motor 30 to be directly connected to the load-bearing body 40, and the motor 30 is supported on the load-bearing body 40.

[0053] For example, the mounting foot 10 has a mounting hole 11 and a support end 12, the mounting column 20 has a limit portion 21 and a first end, the first end of the mounting column 20 is fixed to the load-bearing body 40, and the motor 30 is suspended from the load-bearing body 40 through the mounting assembly. When the first magnetic part 13 and the second magnetic part 22 are not powered on and the first repulsive force is not generated, under the weight of the motor 30 itself, the support end 12 of the mounting foot 10 is pressed on the limit portion 21, and the mounting foot 10 will not be separated from the mounting column 20 under the restriction of the limit portion 21, and the motor 30 can be suspended from the load-bearing body 40. When the first magnetic part 13 and / or the second magnetic part 22 are powered on, the first repulsive force separates the support end 12 from the limit portion 21, and the rod of the mounting column 20 moves axially in the mounting hole 11, driving the motor 30 to move axially and suspend.

[0054] Of course, in other embodiments, the second end of the mounting column 20 may be fixedly connected to the load-bearing body 40, the mounting foot 10 may be limited between the first end and the limiting portion 21, and the motor 30 may be installed above the load-bearing body 40 through the mounting assembly, which will not be described in detail.

[0055] Further, when the mounting foot 10 has the above-mentioned support end 12 and the mounting column 20 has the above-mentioned limit portion 21, the first magnetic portion 13 is configured at the support end 12 of the mounting foot 10, and the second magnetic portion 22 is configured at the limit portion 21 of the mounting column 20. When the mounting column 20 has the above-mentioned support end 12 and the mounting foot 10 has the above-mentioned limit portion 21, the first magnetic portion 13 is configured at the limit portion 21 of the mounting foot 10, and the second magnetic portion 22 is configured at the support end 12 of the mounting column 20.

[0056] The limiting part 21 may be hollow, and the magnetic part is located in the limiting part 21. The support end 12 has a recess, and the magnetic part is located in the recess. The limiting part 21 may be block-shaped, plate-shaped, etc., and is not limited to the specific shape.

[0057] Furthermore, a plurality of first magnetic parts 13 are evenly arranged along the central axis of the mounting foot 10 , a plurality of second magnetic parts 22 are evenly arranged along the central axis of the mounting column 20 , and the plurality of first magnetic parts 13 and the plurality of second magnetic parts 22 are arranged one-to-one correspondingly.

[0058] In actual operation, each first magnetic part 13 and / or each second magnetic part 22 is powered on or off at the same time, so that each first magnetic part 13 and the corresponding second magnetic part 22 respectively generate repulsive forces so that the support end 12 leaves the limit part 21. At this time, each repulsive force is evenly distributed, so that the interval between the support end 12 and the limit part 21 is equal everywhere. In this way, the suspension height of the motor 30 is uniform, which helps to improve the stability of the magnetic suspension connection between the motor 30 and the load-bearing body 40 and maintain the position stability of the motor 30.

[0059] It should be noted that in the embodiments of the present application, "plurality" includes "two".

[0060] The plurality of first magnetic parts 13 may be arranged in a circular array or a matrix array around the central axis of the mounting foot 10, and the center of gravity of the plurality of first magnetic parts 13 is located at the central axis of the mounting foot 10. The plurality of second magnetic parts 22 may be arranged in a circular array or a matrix array around the central axis of the mounting post 20, and the center of gravity of the plurality of second magnetic parts 22 is located at the central axis of the mounting post 20.

[0061] It can be understood that since the mounting foot 10 and the mounting column 20 are movably connected, that is, since there may be position deflection when the motor 30 vibrates, when the motor 30 is running, the central axis of the mounting foot 10 and the central axis of the mounting column 20 can be parallel, overlap, or intersect.

[0062] Specifically in the embodiment, see Figure 2 and Figure 4 The number of the mounting feet 10 and the number of the mounting columns 20 are both multiple, and the multiple mounting feet 10 and the multiple mounting columns 20 are installed one by one. The multiple mounting feet 10 are configured to be evenly arranged around the central axis of the motor 30, and the multiple mounting columns 20 are configured to be evenly arranged around the central axis of the motor 30.

[0063] At this time, multiple mounting feet 10 and multiple mounting columns 20 are used to connect the motor 30 and the load-bearing body 40, so that the connection between the motor 30 and the load-bearing body 40 is more stable. At the same time, when the sum of the repulsive forces generated by the first electromagnets of each mounting foot 10 and mounting column 20 and the first permanent magnet is greater than or equal to the gravity of the motor 30, the motor 30 can be magnetically suspended and connected to the load-bearing body 40. At this time, multiple first electromagnets are energized to generate repulsive forces to achieve magnetic suspension connection. Compared with the concentrated force on the motor 30 when a single first electromagnet is energized to generate repulsive forces to achieve magnetic suspension connection, the force on the motor 30 is dispersed and uniform in the magnetic suspension state, so that the motor 30 is supported more stably in the magnetic suspension state and is more energy-efficient.

[0064] The plurality of mounting feet 10 may be arranged in a circumferential array or a matrix array around the first axis, and the center of gravity of the plurality of mounting feet 10 is located at the central axis of the motor 30 to ensure the position stability of the motor 30. The plurality of mounting posts 20 may be arranged in a circumferential array or a matrix array around the central axis of the mounting posts 20, and the center of gravity of the plurality of mounting posts 20 is located at the central axis of the motor 30 to ensure the position stability of the motor 30.

[0065] In other embodiments, it is not excluded that the mounting assembly only includes one mounting foot 10 and one mounting column 20 to achieve a solution of connecting the motor 30 and the load-bearing body 40 .

[0066] Optionally, the mounting assembly further comprises a first mounting plate, a plurality of mounting posts 20 are mounted on the first mounting plate, and the plurality of mounting posts 20 are fixedly mounted on the load-bearing body 40 through the first mounting plate. In this way, assembly and disassembly can be accelerated. The signal transmitting portion 52 or the signal receiving portion 51 mentioned in the subsequent embodiments and configured to be fixedly mounted relative to the mounting posts 20 can be directly mounted on the first mounting plate.

[0067] Optionally, the mounting assembly further comprises a second mounting plate, a plurality of mounting feet 10 are mounted on the second mounting plate, and the plurality of mounting feet 10 are fixedly mounted on the motor 30 via a second mounting column 20. In this way, assembly and disassembly can be accelerated. The signal transmitting portion 52 or the signal receiving portion 51 mentioned in the subsequent embodiments and configured to be fixedly mounted relative to the mounting column 20 can be directly mounted on the second mounting plate.

[0068] In some embodiments, the motor 30 is configured such that its own central axis is arranged along a preset axis. The motor assembly further includes a second action member, which is configured on one of the motor 30 or the load-bearing body 40 and is controlled to generate a second action force that drives the motor 30 to move in any plane perpendicular to the preset axis, so that the central axis of the motor 30 is located on the preset axis.

[0069] In actual operation, when the motor 30 is in operation, the center of gravity of the motor 30 may deflect due to the effect of its wind field. At this time, the force generated by the second action member causes the motor 30 to move in any plane perpendicular to the preset axis to correct the center of gravity of the motor 30. In this way, the stability of the operation of the motor 30 can be improved, and when the center of gravity of the motor 30 deviates and interferes with the load-bearing body 40 or other structures, the vibration of the motor 30 is transmitted to the load-bearing body 40 or other structures to resonate and generate noise.

[0070] The second force is used to provide a moving signal and / or moving medium to one of the motor 30 and the load-bearing body 40, which enables the motor 30 to move in any plane perpendicular to the preset axis. The moving signal can be an electromagnetic signal, a permanent magnetic signal or a high-frequency sound signal. The suspension medium can be suspended particles or air (refer to gas suspension technology and particle beam suspension technology).

[0071] Specifically in the embodiment, see Figure 3 The second action member includes a third magnetic part 14 and a fourth magnetic part 23. The third magnetic part 14 is disposed on the motor 30, and the fourth magnetic part 23 is disposed on the load-bearing body 40. At least one of the third magnetic part 14 and the fourth magnetic part 23 includes an electromagnet, and the other includes an electromagnet or a permanent magnet. When the third magnetic part 14 and / or the fourth magnetic part 23 are energized, a second repulsive force can be generated to move the motor 30 in any plane perpendicular to the preset axis.

[0072] It can be understood that the third magnetic part 14 and the fourth magnetic part 23 can both be electromagnets. When both are powered on, magnetic poles can be formed at both ends of each electromagnet, and the second repulsive force can be generated by arranging the same magnetic poles of the third magnetic part 14 and the fourth magnetic part 23 relative to each other. Alternatively, one of the third magnetic part 14 and the fourth magnetic part 23 is an electromagnet and the other is a permanent magnet. After the electromagnet is powered on, magnetic poles are formed at both ends, and the second repulsive force can be generated when the same magnetic poles are arranged relative to the permanent magnet.

[0073] At this time, the second repulsive force generated by the two magnetic parts can make the motor 30 move in a plane perpendicular to the preset axis, which is convenient for simplifying the structure of the motor assembly and reducing costs compared to other suspension technologies (such as airflow suspension technology). At least one electromagnet in the two magnetic parts can control the repulsive force generated by the two magnetic parts by connecting the current of the electromagnet, which is convenient for controlling the moving distance of the motor 30.

[0074] Specifically in the embodiment, see Figure 3 The third magnetic portion 14 is disposed on the hole wall of the mounting hole 11 of the mounting foot 10 , and the fourth magnetic portion 23 is disposed in the rod portion of the mounting column 20 and is arranged corresponding to the third magnetic portion 14 .

[0075] In actual operation, when the first magnetic part 13 and / or the second magnetic part 22 are powered on, the support end 12 of the mounting foot 10 is separated from the limiting part 21. At this time, there is a possibility that the axial circumferential wall of the rod of the mounting column 20 is in contact with the hole wall of the mounting hole 11. The vibration generated when the motor 30 is running can be transmitted to the load-bearing body 40 through the hole wall of the mounting hole 11 and the mounting column 20, thereby generating noise. At this time, when the third magnetic part 14 and / or the fourth magnetic part 23 are powered on, a second repulsive force is generated until the hole wall of the mounting hole 11 is separated from the axial circumferential wall of the rod of the mounting column 20, thereby completely cutting off the vibration transmission path between the motor 30 and the load-bearing body 40, and avoiding the resonance between the motor 30 and the load-bearing body 40 to generate noise. The magnitude of the second repulsive force can be controlled by controlling the magnitude of the current when the third magnetic part 14 and / or the fourth magnetic part 23 are powered on, ensuring that the center of gravity of the motor 30 does not deviate.

[0076] Specifically in the embodiment, see Figure 3 and Figure 5 The number of the third magnetic parts 14 and the number of the fourth magnetic parts 23 are both multiple, and the multiple third magnetic parts 14 are evenly distributed on the hole wall of the mounting hole 11 around the central axis of the mounting foot 10, and the multiple fourth magnetic parts 23 are evenly distributed in the rod part around the central axis of the mounting column 20, and the multiple third magnetic parts 14 correspond to the multiple fourth magnetic parts 23 one by one.

[0077] In actual operation, each third magnetic part 14 and fourth magnetic part 23 are powered on or off at the same time, so that each group of third magnetic parts 14 and fourth magnetic parts 23 generates a repulsive force from each direction to separate the axial peripheral wall of the rod of the mounting column 20 from the hole wall of the mounting hole 11. Each repulsive force is evenly distributed, so that the interval between the axial peripheral wall of the rod of the mounting column 20 and the hole wall of the mounting hole 11 is equal at each place. In this way, it is helpful to maintain the position stability of the motor 30 and prevent the position of the motor 30 from deflecting.

[0078] It can be understood that the electromagnets include an iron core and a winding wound on the iron core, and the winding is connected to an external circuit (for example, when the winding is located at the mounting column 20, the external circuit is the circuit of the skylight unit. When the skylight unit is working, each electromagnet is energized to promptly cut off the vibration transmission path between the unit and the motor 30. When the winding is located at the mounting foot 10, the external circuit is the circuit of the motor 30. When the motor 30 is working, the electromagnets are energized to promptly cut off the vibration transmission path between the unit and the motor 30) and current flows to generate a magnetic field. The winding is connected to the external circuit through a charging and discharging circuit to prevent the motor 30 from falling and being damaged when the unit or the motor 30 is instantly powered off. The specific form of the charging and discharging circuit is not limited here.

[0079] In some embodiments, the mounting assembly further includes a controller and a position sensor 50, the controller is electrically connected to the position sensor 50, the position sensor 50 is used to detect the suspension distance between the motor 30 and the load-bearing body 40, and the controller is used to control the magnitude of the first force generated by the first action member according to the suspension distance. In this way, the controller can make the motor 30 dynamically suspended at a balanced position to avoid excessive or insufficient instantaneous force causing the motor 30 to vibrate more violently or even be damaged.

[0080] The position sensor 50 may be a photoelectric sensor, such as a laser sensor, an infrared sensor, or an ultrasonic sensor. In this way, the signal receiving unit 51 is not directly connected to the signal transmitting unit 52 to avoid transmitting the vibration of the motor 30 to the load-bearing body 40.

[0081] Specifically in the embodiment, see Figure 1 and Figure 4 The position sensor 50 includes an adapted signal transmitting part 52 and a signal receiving part 51, one of which is configured to be fixedly arranged relative to the mounting foot 10, and the other of which is configured to be fixedly arranged relative to the mounting column 20. The controller is electrically connected to the signal receiving part 51 and the signal transmitting part 52, and is used to obtain the vector distance between the signal receiving part 51 and the signal transmitting part 52, and control the current connected to the first magnetic part 13 and / or the second magnetic part 22 according to the first distance of the vector distance in the axial direction of the motor 30 until the first distance is equivalent to the first preset distance.

[0082] In actual operation, the distance between the signal transmitting part 52 and the signal receiving part 51 changes with the position change of the motor 30. At this time, by obtaining the vector distance between the signal transmitting part 52 and the signal receiving part 51 of the position sensor 50 in real time, it is judged whether the motor 30 has an improper suspension position in the first direction according to the first distance of the vector distance in the axial direction of the motor 30 and the first preset distance. When there is an improper suspension position, the magnitude of the current connected to the first magnetic part 13 and / or the second magnetic part 22 is controlled to change the magnitude of the first repulsive force, thereby changing the suspension position of the motor 30 until the suspension position of the motor 30 is at a preset horizontal position.

[0083] Furthermore, the signal receiving unit 51 and the signal transmitting unit 52 are both arranged on the central axis of the motor 30. At this time, when each electromagnet is not energized, the distance direction between the signal receiving unit 51 and the signal transmitting unit 52 is parallel to the suspension direction of the motor 30. In this way, it is helpful to simplify the calculation process of obtaining the first distance and the second distance according to the vector distance, reduce the computing power requirements of the controller, and thus reduce the cost of the controller.

[0084] Furthermore, the signal receiving part 51 or the signal transmitting part 52 which is fixedly arranged relative to the mounting column 20 is installed on the load-bearing body 40 , and the signal receiving part 51 or the signal transmitting part 52 which is fixedly arranged relative to the mounting foot 10 is installed on the motor 30 .

[0085] At this time, the first distance measured by the signal receiving unit 51 and the signal transmitting unit 52 is the real-time distance between the motor 30 and the load-bearing body 40. When in a balanced state, the distance between the motor 30 and the load-bearing body 40 is a first preset distance. When the first distance is greater than the first preset distance, it means that the motor 30 is lower than the equilibrium position, and it is necessary to control the current connected to the first magnetic part 13 and / or the second magnetic part 22 to increase, increase the first repulsive force, and make the motor 30 rise to the equilibrium position. When the first distance is less than the first preset distance, it means that the motor 30 is higher than the equilibrium position, and it is necessary to control the current connected to the first magnetic part 13 and / or the second magnetic part 22 to decrease, reduce the first repulsive force, and make the motor 30 fall back to the equilibrium position.

[0086] In other embodiments, the signal receiving part 51 or the signal transmitting part 52 configured to be fixedly arranged relative to the mounting column 20 may also be installed on one side of the limiting part 21 relative to the supporting end 12 of the mounting foot 10, and the signal receiving part 51 or the signal transmitting part 52 configured to be fixedly arranged relative to the mounting foot 10 is installed at the supporting end 12 of the mounting foot 10. In this case, the signal receiving part 51 and the signal transmitting part 52 directly measure the floating distance of the motor 30.

[0087] The controller may be an industrial computer, a central processing unit, a microprocessor, an embedded single-chip microcomputer or other device with processing functions, which is not limited here. The specific control method of the controller is determined according to the installation position of the position sensor 50, which is not limited here.

[0088] In some embodiments, the position sensor is also used to detect the eccentric distance between the axis of the motor 30 and the preset axis, and the second force generated by the second acting member is adjusted according to the eccentric distance so that the central axis of the motor 30 is located on the preset axis.

[0089] In actual operation, when the motor 30 is a motor 30, the center of gravity of the motor 30 will deviate due to the wind field of the fan blades during the operation of the motor 30. At this time, the eccentric distance of the motor 30 is measured by the position sensor 50, and the controller controls the motor 30 to move in any plane perpendicular to the preset axis according to the eccentric distance, so that the center of gravity of the motor 30 is always located on the preset axis. In this way, the stability of the operation of the motor 30 can be improved, and the deflection of the center of gravity caused by the wind field of the fan blades when the motor 30 is running can be adjusted in real time, so that the motor 30 is always in a dynamic balance state, and it can also avoid the interference of the center of gravity of the motor 30 with the load-bearing body 40 or other structures when the center of gravity of the motor 30 deviates, and the vibration of the motor 30 is transmitted to the load-bearing body 40 or other structures to resonate and generate noise.

[0090] Specifically in the embodiment, the controller is also used to control the current connected to the third magnetic part 14 and / or the fourth magnetic part according to the second distance of the vector distance between the signal receiving part 51 and the signal transmitting part 52 on the first plane perpendicular to the axis of the motor 30 until the second distance is equivalent to the second preset distance.

[0091] In actual operation, the distance between the signal transmitting part 52 and the signal receiving part 51 of the position sensor 50 changes with the position change of the motor 30 when the motor 30 is eccentric. At this time, the second distance of the vector distance on the first plane is the eccentric distance of the motor 30. However, when there is eccentricity, the controller can accurately control the magnitude of the current passed through each magnetic part to change the center of gravity position of the motor 30. In this way, the same set of position sensors 50 can be used to control each magnetic part, which helps to simplify the structure and reduce costs.

[0092] It can be understood that the second distance and the second preset distance are both plane vector distances, which can be decomposed into a distance score in the second direction and a distance score in the third direction located on the first plane. By comparing the distance score of the second distance in the second direction with the distance score of the second preset distance in the second direction, it is determined whether the center of gravity of the motor 30 is offset in the second direction. By comparing the distance score of the second distance in the third direction with the distance score of the second preset distance in the third direction, it is determined whether the center of gravity of the motor 30 is offset in the third direction.

[0093] Among them, the second preset distance can be (0,0), indicating that the eccentricity is zero under normal circumstances, and the second distance can be (y1,y2), indicating that the eccentricity distance of the center of gravity of the motor 30 in the second direction is y1, and the eccentricity distance in the third direction is y2.

[0094] The specific control process of the controller is determined according to the number and arrangement angle of the third magnetic parts 14 and the fourth magnetic parts 23, and is not limited here. Optionally, the number of the third magnetic parts 14 and the fourth magnetic parts 23 are both six.

[0095] In some embodiments, the control method of the controller includes the following steps:

[0096] The vector distance measured by the position sensor 50 is acquired.

[0097] The relationship between a first distance of the vector distance in the axial direction of the motor 30 and a first preset distance is determined.

[0098] When the first distance is equal to the first preset distance, the first preset current is controlled to be input to the first magnetic portion 13 and / or the second magnetic portion 22 .

[0099] When the first distance is not equal to the first preset distance, the first control current is calculated according to the difference between the first distance and the first preset distance, and the first current is controlled to be input to the first magnetic part 13 and / or the second magnetic part 22, and the first current is equal to the sum of the first preset current and the first control current.

[0100] At this time, when the first distance is not equal to the first preset distance, the first control current is calculated according to the difference between the two, and the first control current is used to adjust the first preset current to obtain the first current, so that the motor 30 returns to the equilibrium position under the repulsive force generated when the first current is passed through the first magnetic part 13 and / or the second magnetic part 22. The first control current is a vector current.

[0101] Furthermore, the control method of the controller, after the step of acquiring the vector distance measured by the position sensor 50, further includes:

[0102] Determine the relationship between a second distance of the vector distance in a first plane perpendicular to the axial direction of the motor 30 and a second preset distance.

[0103] When the second distance is equal to the second preset distance, the second preset current is controlled to be input to the third magnetic portion 14 and / or the fourth magnetic portion 23 .

[0104] When the second distance is not equal to the second preset distance, the second control current is calculated according to the difference between the second distance and the second preset distance, and the second current is controlled to be input to the third magnetic part 14 and / or the fourth magnetic part 23, and the second current is equal to the sum of the second preset current and the second control current.

[0105] At this time, when the second distance is not equal to the second preset distance, the second control current is calculated according to the difference between the two, and the second control current is used to adjust the second preset current to obtain the second current, so that the center of gravity of the motor 30 returns to the initial position under the repulsive force generated when the second current is passed through the third magnetic part 14 and / or the fourth magnetic part 23. Among them, the second control current is a vector current. The second distance and the second preset distance are both vector distances.

[0106] The motor assembly provided in the embodiment of the present application can suspend the motor 30 and the load-bearing body 40, so that the vibration generated by the motor 30 during operation cannot be transmitted to the load-bearing body 40, avoiding the noise caused by the resonance between the motor 30 and the load-bearing body 40, thereby greatly improving the comfort of the user.

[0107] In addition, an embodiment of the present application further provides an electrical device, including a load-bearing body 40 and the above-mentioned motor assembly. Since the electrical device includes the above-mentioned installation assembly, all the beneficial effects of the above-mentioned installation assembly are not described in detail here.

[0108] The electrical equipment may be a patio machine, a ceiling fan, etc. When the electrical equipment is a patio machine, it also includes a machine set, which can serve as a load-bearing body 40. When the motor 30 and the machine set are running at the same time, the noise caused by the resonance between the motor 30 and the machine set can be avoided, which greatly improves the comfort of the user.
