Technical Field

[0001] This utility model relates to the field of motor technology, specifically to an assembled motor. Background Technology

[0002] Existing motors typically connect speed controllers to the motor via wires and junction boxes, or by using pins. However, the wire connection method is cumbersome and requires connecting multiple wires, while the pin connection method suffers from insufficient strength due to the small contact area of ​​the pins, resulting in unstable connections. Therefore, our company designed this modular motor to solve the problem of unstable connections. Meanwhile, the motor mounting structure was improved. Traditional motors do not have a front cover; the front cover and the housing are molded as one piece. When replacing the rotor, the rear cover and the ESC part need to be completely removed. Too many parts need to be disassembled, which seriously affects maintenance efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an assembled motor, which has an end cover connected to the upper end of the housing, and a PCB board set between the end cover and the partition. The speed controller is directly plugged in by the inserts on the PCB board to make the connection stable. At the same time, a front cover and a support base are detachably connected to the other end of the housing, which makes the motor easy to disassemble and improves maintenance efficiency.

[0004] This utility model provides the following technical solution: an assembled motor, including a housing, a rotating shaft rotatably connected to the center of the housing, a stator and a rotor connected to the rotating shaft, a partition fixed to one end of the housing, an end cover connected to the partition by bolts, a PCB board disposed between the end cover and the partition, inserts connected to the PCB board, the ends of the inserts located on the surface of the end cover, a front cover fixed to the other end of the housing by bolts, a support seat connected to one side of the front cover by a bearing, and the front cover and the support seat sleeved on the rotating shaft.

[0005] According to the above technical solution, countersunk holes are provided on both sides of the housing, and positioning screws are threaded into the countersunk holes. The positioning screws are located above the rotor. A retaining plate is formed on the inner wall of the housing, and there is a gap between the retaining plate and the rotor. The positioning screws are located in the gap. The positioning screws are screwed out to support the housing and prevent the housing from shaking when the motor is running.

[0006] According to the above technical solution, the front cover is formed with a groove, and the bottom of the support base is formed with a plug-in block corresponding to the groove. The plug-in block is connected to the groove by bolts, so that one end of the housing is detachable and the internal rotor is easy to replace.

[0007] According to the above technical solution, a one-way bearing is inserted into the support base, and the one-way bearing is sleeved on the front cover to position the rotation direction of the motor and prevent the problem of incorrect rotation direction.

[0008] According to the above technical solution, the partition plate has a waist hole, and the PCB board is also equipped with a PIN pin. The PIN pin is inserted into the waist hole and connected to the motor, which facilitates the installation and wiring of the PIN pin.

[0009] According to the above technical solution, multiple heat dissipation holes are provided on the surface of the housing to dissipate heat from the housing and reduce the temperature rise of the motor.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) Connect an end cover to the upper end of the housing, and set a PCB board between the end cover and the partition.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1 to 4 This utility model provides a technical solution: an assembled motor, including a housing 2, with a rotating shaft 5 rotatably connected to the center of the housing 2 via a bearing. A stator and a rotor are sleeved on the rotating shaft 5, with the stator fixed on the rotating shaft 5 and the rotor rotating outside the stator. Both the rotor and the stator are located inside the housing 2. A partition 23 is fixed to one end of the housing 2, and an end cover 1 is bolted to the partition 23. A center cover plate 11 is formed on the upper end of the end cover 1 for foolproof design to distinguish parts and prevent incorrect installation. A PCB board 3 is provided between the end cover 1 and the partition 23, and the PCB board 3 is bolted to the partition 23. Inserts 31 are inserted and fixed on the PCB board 3, with the ends of the inserts 31 located on the end cover 1. On the surface, the plug 31 is used to connect to the speed controller, which facilitates the adjustment of the motor's rotational speed. At the same time, the plug 31 is also used to connect to the gearbox, which has a large contact surface and good stability. Compared with wire connection, it is more convenient to connect, has a longer service life, and is less prone to poor contact problems. The other end of the housing 2 is fixed with a front cover 4 by bolts. A support seat 6 is connected to one side of the front cover 4 by a bearing. The front cover 4 and the support seat 6 are fitted onto the rotating shaft 5. The front cover 4 and the support seat 6 provide axial positioning of the rotating shaft 5. At the same time, the housing 2 is sealed by a detachable structure, which makes the motor easy to disassemble and assemble. When the rotor is replaced, it is no longer necessary to remove the speed controller. It can be disassembled from the other side of the motor, which improves maintenance efficiency and reduces maintenance costs.

[0014] like Figure 5As shown, countersunk holes are provided on both sides of the housing 2, and positioning screws 21 are threaded into the countersunk holes. The positioning screws 21 are located above the rotor. A retaining plate 25 is formed on the inner wall of the housing 2. There is a gap between the retaining plate 25 and the rotor. The positioning screws 21 are located in the gap to avoid interference between the positioning screws 21 and the internal parts. By rotating the positioning screws 21, the extension distance of the threads of the positioning screws 21 can be adjusted. Furthermore, the positioning screws 21 can support the housing 2 in any usage scenario, while preventing the housing 2 from shaking when the motor is running.

[0015] like Figure 3 As shown, a groove 41 is formed on the front cover 4, and a plug block 61 corresponding to the groove 41 is formed on the bottom of the support base 6. The plug block 61 is connected to the groove 41 by bolts, so that the front cover 4 and the support base 6 are fixed together, which makes it convenient to disassemble the front cover 4 and the support base 6 and to repair and replace the rotor. Compared with the traditional motor where the front cover 4 and the housing 2 are integrally formed, it is convenient to remove parts for repair and reduce maintenance costs.

[0016] like Figure 2 As shown, a one-way bearing 62 is inserted into the support base 6. The one-way bearing 62 is sleeved inside the front cover 4. At the same time, the rotating shaft 5 is also inserted and fixed inside the one-way bearing 62, so that the motor also rotates in one direction, effectively preventing the motor from reversing.

[0017] The partition 23 has a waist hole 24, and a PIN pin is also inserted into the PCB board 3. The PIN pin is inserted into the waist hole 24 and connected to the motor. Through the connection between the PIN pin on the PCB board 3 and the motor, the motor's running signal is transmitted to the PCB board 3, and the connection between the motor and the speed controller is controlled by the PCB board 3.

[0018] like Figure 4 As shown, multiple heat dissipation holes 22 are provided on the surface of the housing 2. The heat dissipation holes 22 improve the heat dissipation efficiency of the housing 2, reduce the temperature rise of the motor, and extend its service life.

[0019] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
