[0041] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the present invention can be combined interchangeably without conflicting with each other.

[0042] First embodiment

[0043] Reference Figure 1 and Figure 2 The motor in this embodiment includes a stator 10 and a rotor 20. The stator 10 and the rotor 20 are both in a closed loop shape, so that the inside of the stator 10 and the rotor 20 are hollow. The rotor 20 is arranged outside the stator 10. A plurality of winding groups 11 are arranged along the circumference of the stator 10. The rotor 20 is provided with a magnetic ring 21 on the side close to the stator 10, that is, the magnetic ring 21 is arranged on the inner ring of the rotor 20.

[0044] The magnetic ring 21 in this embodiment can be a permanent magnet. When the winding group 11 on the stator 10 is energized, a magnetic field is generated. The magnetic field interacts with the magnetic field generated by the magnetic ring 21 to drive the rotor 20 to rotate, thereby achieving the rotation performance of the rotor 20.

[0045] The stator 10 and the rotor 20 in this embodiment both adopt an annular structure. The interior of the stator 10 is hollow, and the rotor 20 is connected to the external actuator as the power connection end of the motor, which simplifies the motor structure and makes the motor lighter. By connecting the corresponding actuator to the rotor 20, the power transmission from the motor to the external device can be realized. The motor has high transmission efficiency and power, and adopts the form of an outer rotor and an inner stator, which improves the rotational inertia and heat dissipation performance of the motor, making the motor run more smoothly.

[0046] In this embodiment, a support portion 30 is provided between the stator 10 and the rotor 20, and the support portion 30 is used to connect the stator 10 and the rotor 20. The support portion 30 includes a first connection unit 31 and a second connection unit 32 that are rotatably connected. The first connection unit 31 and the second connection unit 32 are both closed-loop structures. The first connection unit 31 is sleeved on the outside of the second connection unit 32. The first connection unit 31 is relatively fixed to the rotor 20, and the second connection unit 32 is relatively fixed to the stator 10. When the rotor 20 rotates relative to the stator 10, the first connection unit 31 rotates with the rotor 20 to achieve relative rotation between the first connection unit 31 and the second connection unit 32. In this embodiment, the outer wall of the first connection unit 31 fits the inner wall of the rotor 20, and the outer wall of the second connection unit 32 is connected to the stator 10. By setting a rotatable connection between the first connection unit 31 and the second connection unit 32, the rotor 20 and the stator 10 can maintain relative rotation.

[0047] A plurality of rolling bodies 33 are provided between the first connection unit 31 and the second connection unit 32. The rolling bodies 33 can roll following the relative rotation between the first connection unit 31 and the second connection unit 32, so that rolling friction is formed between the first connection unit 31 and the second connection unit 32, thereby improving the power transmission efficiency between the first connection unit 31 and the second connection unit 32 and the power driving efficiency of the motor.

[0048] It also includes a fixing seat 40, on which the stator 10 is mounted and fixedly connected. In this embodiment, the stator 10 and the fixing seat 40 are relatively fixed by inserting a locking member into the stator 10 and the fixing seat 40. The second connecting unit 32 and the stator 10 are tightly matched, so that the second connecting unit 32 and the fixing seat 40 remain relatively fixed during the rotation of the rotor 20. The fixing seat 40 in this embodiment is also a closed-loop structure, so that the inside of the motor is hollow, ensuring that the motor is lightweight and has high working efficiency.

[0049] Preferably, the stator 10 in this embodiment can be arranged outside the support part 30, and the rotor 20 can be arranged inside the support part 30. By adopting the outer stator and inner rotor mode, the actuator is connected inside the rotor 20, and the rotor 20 can also drive the actuator.

[0050] Second embodiment

[0051] Reference Figures 3 to 5The present embodiment is different from the first embodiment in that a plurality of support parts 30 are arranged along the circumference of the rotor 20 in the present embodiment. By reducing the specifications and dimensions of the support parts 30, the processing difficulty and processing cost of the support parts 30 are reduced. The support part 30 also includes a first connecting unit 31 and a second connecting unit 32. The first connecting unit 31 is relatively fixed to the rotor 20, and the second connecting unit 32 is relatively fixed to the fixing seat 40. The support part 30 is in point contact with the fixing seat 40 and the rotor 20. By providing a plurality of support parts 30, a multi-point support effect is achieved between the support part 30 and the fixing seat 40 and the rotor 20. On the premise of supporting the rotor 20 and the stator 10, the rotation of the rotor 20 relative to the stator 10 is realized.

[0052] In this embodiment, two support parts 30 are arranged in parallel based on the axial direction of the stator 10 to improve the stability of the rotation process of the rotor 20 and prevent the rotor 20 from tilting. The support part 30 also includes a third connecting unit 34, which passes through the support part 30, the stator 10 and another support part 30 in sequence from between the first connecting unit 31 and the second connecting unit 32 and is locked to achieve relative fixation between the stator 10 and the second connecting unit 32.

[0053] The support part 30 in this embodiment can also be provided based on the axial direction of the rotor 20 , and the structure of the support part 30 can be simplified under the premise of ensuring that the support part 30 connects and supports the stator 10 and the rotor 20 .

[0054] The fixing seat 40 and the stator 10 are both in a closed loop shape. The interior of the stator 10 is hollow. The stator 10 includes a mounting base 12. The mounting base 12 is annular and is mounted on the end surface of the fixing seat 40. The edge of the mounting base 12 protrudes outward with multiple mounting positions for the support part 30 to be installed. The mounting positions are inserted between adjacent winding groups 11 to meet the multi-point support requirements of the support part 30.

[0055] In this embodiment, three support parts 30 are provided, and the three support parts 30 form three support positions, and the three support positions form a support plane, so that the support parts 30 maintain stable support for the fixing seat 40 and the rotor 20. Preferably, the support parts 30 are evenly distributed along the circumference of the rotor 20 to ensure the stability of the rotation of the rotor 20 relative to the stator 10.

[0056] The rotor 20 in this embodiment can be located inside the stator 10. The rotor 20 and the stator 10 are also supported by the support part 30. The rotor 20 is in a closed loop shape. The interior of the rotor 20 is hollow. The rotor 20, as a power connection end, can drive the actuator connected to the inside thereof.

[0057] Third embodiment

[0058] Reference Figures 6 to 8, this embodiment is different from the second embodiment in that the stator 10 in this embodiment includes no less than two magnetic units 100, and the magnetic units 100 are arranged along the circumference of the stator. Since the stator 10 is generally formed by stacking silicon steel sheets, the structure of the stator 10 is formed by combining the magnetic units 100, so that the stator 10 can be processed based on small-sized silicon steel sheets, reducing the generation of waste and reducing production costs. In this embodiment, three magnetic units 100 are provided, and the magnetic units 100 are evenly distributed along the circumference of the rotor 20. The size of each magnetic unit 100, the number of magnetic units 100, and the number of winding groups 11 included in each magnetic unit 100 can be reasonably selected according to actual use requirements, and the number of winding groups 11 on different magnetic units 100 can be set to the same or different numbers.

[0059] Adjacent winding groups 11 are arranged at intervals, and a portion of the fixing seat 40 is accommodated between adjacent winding groups 11. Specifically, the fixing seat 40 includes a fixing area 41 and an installation area 42, and the fixing area 41 and the installation area 42 are arranged at intervals. The magnetic unit 100 is installed on the installation area 42, and the support portion 30 is installed on the fixing area 41. The fixing area 41 is protruding to provide a mounting surface for the support portion 30, and the installation area 42 is concave to provide an accommodation space for the winding group 11. The magnetic unit 100 is distributed along the circumference of the rotor 20 by splicing the magnetic unit 100 on the fixing seat 40. The size and number of the fixing area 41 and the installation area 42 can be selected according to the specific specifications of the magnetic unit 100 and the rotor 20 and the use requirements of the motor.

[0060] The mounting base 12 of the magnetic unit 100 is installed on the mounting area 42 of the fixing base 40, the support part 30 is installed on the fixing area 41 of the fixing base 40, the winding group 11 includes a winding post 111 and a coil 112 wound on the winding post, and the winding post 111 is integrally connected to the mounting base 12; the mounting base 12 is fan-shaped, and the mounting base 12 is fixed to the fixing base 40 by threaded fasteners.

[0061] In this embodiment, two parallel support parts 30 may also be provided at the installation position of each support part 30 . The two support parts 30 support the rotor 20 and the fixing seat 40 at the same time. The fixing seat 40 is located at the center point between the two support parts 30 .

[0062] The third connection unit 34 passes through the support portion 30 , the fixing seat 40 and another support portion 30 in sequence from between the first connection unit 31 and the second connection unit 32 and is locked, so as to achieve relative fixation between the stator 10 and the second connection unit 32 .

[0063] The rotor 10 in this embodiment serves as a power connection end connected to an external actuator to achieve power output of the motor; the fixed seat 40 is annular and hollow inside, and is not connected to other components. The magnetic unit 100 is spliced ​​on the fixed seat 40 to form a complete stator 10.

[0064] Fourth embodiment

[0065] Reference Figures 9 to 11 The stator 10 in this embodiment includes three magnetic units 100. Different from the third embodiment, the magnetic units 100 in this embodiment are arranged outside the rotor 20. The rotor 20 is in a closed ring shape. The interior of the rotor 20 is hollow. The rotor 20 is connected to the actuator as a power connection end to realize the power transmission of the motor. The magnetic ring 21 is arranged on the outer wall of the rotor 20, the mounting base 12 is located at the outer edge of the magnetic unit 100, and the winding group 11 is arranged on the inner wall of the mounting base 12. After the magnetic unit 100 is energized, the rotor 20 can rotate inside the rotor 20 under the action of the magnetic field force. By connecting the transmission element at the inner wall of the rotor 20, the power drive of the motor to other elements can be realized. The rotor 20 in this embodiment is also in a closed loop type. The interior of the rotor 20 is hollow. On the premise of realizing the transmission of power from the rotor 20 to the structure installed inside it, the motor is made lighter.

[0066] When installing the support part 30, it is necessary to swap the positions of the first connecting unit 31 and the second connecting unit 32 in the support part 30, that is, the first connecting unit 31 is located on the inner side and fixed relative to the rotor 20, the second connecting unit 32 is located on the inner side and fixed relative to the stator 10, and the third connecting unit 34 passes through the support part 30, the fixing seat 40 and another support part 30 in sequence from between the first connecting unit 31 and the second connecting unit 32 and is locked, so as to realize the fixed connection between the magnetic unit 100 and the support seat 30 and the relative rotation between the rotor 20 and the magnetic unit 100.

[0067] Reference Fig.12 ,by Fig. 9 yes Fig.11 Taking the motor shown as an example, an actuator 200 is set inside the rotor 20. In this embodiment, the actuator is a fan as an example. The actuator can also be set as other devices according to the use requirements of the motor. The actuator 200 is embedded in the rotor 20. The rotor 20 is fixedly connected to the actuator 200 as a power connection end, so that when the rotor 20 rotates, the actuator 200 is driven to move. The actuator 200 rotates to realize the fan to discharge air, thereby achieving the power transmission effect of the motor.

[0068] The motor in this embodiment does not output power to the actuator 200 via a rotating shaft, but directly connects the actuator 200 to the rotor 20. The rotation of the rotor 20 is directly transmitted to the actuator 200, and the power transmission efficiency of the motor is high.

[0069] Reference Fig.13 , similarly Figures 9 to 11 Taking the motor shown as an example, a transfer unit 300 is provided between the rotor 20 and the actuator 200. The outer side of the transfer unit 300 is fixedly connected to the rotor 20, and the inner side of the transfer unit 300 is fixedly connected to the actuator 200, so as to realize the fixed connection between the actuator 200 and the rotor 20. The rotor 20, as a power connection end, transmits power to the actuator 200 through the transfer unit 300. When the rotor 200 rotates, the actuator 200 moves with the rotor 20, so as to achieve the power transmission effect of the motor.

[0070] Reference Fig.14 ,by Figure 3 to Figure 4 Taking the motor shown as an example, the rotor 20 is sleeved on the outside of the stator 10, and the actuator 200 is arranged on the outside of the rotor 20. The rotor 20 is fixedly connected to the actuator 200 as a power connection end. When the rotor 20 rotates, the actuator 200 is driven to move, realizing the power transmission from the rotor 20 to the actuator 200, thereby achieving the power transmission effect of the motor.

[0071] In addition, the specific features, structures, functions or characteristics of the present invention can be combined in one or more embodiments in any suitable manner. For example, the first embodiment, the second embodiment, and the fourth embodiment can be combined as long as the specific features, structures, functions or characteristics related to the three embodiments are not mutually exclusive.

[0072] The motor further comprises a casing, in which the stator 10, the rotor 20 and the support part 30 are accommodated. The casing protects the stator 10, the rotor 20 and the support part 30 inside, thereby improving the safety performance of the motor operation.
