The provision of the control panel 8 further reduces the number of wire connections between components, simplifies the interior of the motor, and is conducive to further heat dissipation of the motor. At the same time, by reducing the number of wire connections, the probability of motor failure due to loose bolts at the fixing points of the wire ends is reduced, thereby improving the reliability and practicality of the device.

[0024] like Figure 2 As shown, specifically, the casing 1 is square, and a plurality of heat dissipation fins 9 are provided on the outer wall of the casing 1. A groove 101 is provided on one side of the casing 1, and a power switch 10 is provided on one side of the groove 101. By setting the casing 1 to be square, compared with the traditional round casing 1, the square casing 1 has a more compact structure, which is convenient for installation in tightly integrated areas such as elevators or foyers to control the opening or closing of corresponding door panels.

[0025] Specifically, the heat dissipation effect of the motor is further improved by providing a plurality of heat dissipation fins 9 on the outer wall of the housing 1, and the device can be turned on or off by a power switch 10, so as to facilitate the start-up of the motor or shut down for maintenance.

[0026] like Figure 3 As shown, specifically, a limiting groove 21 is provided on the side wall of the driving cavity 2, a positioning platform 22 is provided in the middle of the driving cavity 2, and a mounting groove 23 is opened in the middle of the positioning platform 22. By passing one end of the driving shaft 41 through the positioning platform 22, the side bearing 12 is positioned and installed in the mounting groove 23 through the positioning platform 22, and then the driving shaft 41 is conveniently installed in the middle of the driving cavity 2.

[0027] like Figure 4As shown, specifically, the stator assembly 3 includes a stator core 31 that is heat-fitted to the inner wall of the drive cavity 2. The stator core 31 is provided with a plurality of tooth slots 32 in a ring shape. The side walls of the tooth slots 32 are provided with an insulating frame 33. The insulating frame 33 is wound with a coil on the outside. By winding the coil (not shown) onto the insulating frame 33 of the stator core 31, and then positioning it through the limiting groove 21, the stator assembly 3 can be quickly heat-fitted into the drive cavity 2, thereby improving the convenience of installation of the stator assembly 3.

[0028] like Figure 2 , 5 and 7, specifically, the drive assembly 4 includes a drive shaft 41 rotatably provided in the middle of the drive cavity 2, the outer circular wall of the drive shaft 41 is provided with a limit table 42, one side of the limit table 42 is provided with a clamping groove 43, a retaining spring 44 is installed in the clamping groove 43, one end of the drive shaft 41 is provided with a threaded hole 45, the threaded hole 45 is connected with a head mounting seat 46, a magnetic head 47 is provided in the middle of the head mounting seat 46, the drive shaft 41 is provided with a keyway 48 away from the threaded hole 45 on the side, a connecting key 49 is installed in the keyway 48, the connecting key 4 9 is connected to a synchronous wheel 410, one side of the synchronous wheel 410 is fitted with an oil seal 411 and the other side of the synchronous wheel 410 is provided with an elastic retaining ring 412. The rotor assembly 5 is guided and installed through the limit platform 42 so that one side of the rotor assembly 5 is fitted with the stepped platform of the drive shaft 41, and then the retaining spring 44 is fitted with the other side of the rotor assembly 5 and installed in the snap-fit ​​groove 43, thereby fixing the rotor assembly 5 to the outer cylindrical wall of the drive shaft 41, and preventing the rotor assembly 5 from rotating axially along the drive shaft 41 by the limit platform 42, thereby ensuring the stability of the rotating assembly and the drive shaft 41 during operation.

[0029] Specifically, the oil seal 411 is provided to prevent the lubricating grease in the mounting groove 23 from leaking out, so that the lubricating grease can be kept in the mounting groove 23 for a long time to lubricate the bearing 12 on the side, thereby ensuring the stability of the rotation of the drive shaft 41.

[0030] Specifically, the magnetic head 47 is an existing technology. By embedding the magnetic head 47 at one end of the drive shaft 41, the drive component 4 has a compact structure, and it is also convenient for the magnetic head 47 to detect the position information of the rotor component 5, so that the control system integrated in the control panel 8 can make correct analysis and judgment on the operating status of the rotor component 5, thereby realizing smooth and efficient operation of the motor.

[0032] Specifically, a weight-reducing groove is provided in the middle of the rotor core 51 , which reduces the weight of the rotor core 51 and effectively reduces the moment of inertia of the rotor assembly 5 during operation, thereby improving the reliability and durability of the inner rotor.

A wire hole 62 is provided on the side wall of the pressure cover 6. By respectively installing the bearings 12 at both ends of the drive shaft 41 into the first mounting groove 23 and the second mounting groove 61, the drive shaft 41 is rotated and set in the drive cavity 2 through the pressure cover 6 and the positioning platform 22, and the wires in the drive cavity 2 are conveniently connected to the control panel 8 through the wire hole 62.

[0034] Specifically, the control panel 8 is a prior art, and the control panel 8 is used to efficiently adjust the motor's voltage, frequency, phase change and other parameters, thereby conveniently controlling the operation of the device.

[0035] The working principle of the present invention is as follows: when in use, the stator assembly 3 is fixed to the top of the limit slot 21 by heat-fitting, thereby reducing the parts for fixing the stator assembly 3, thereby simplifying the internal structure of the drive cavity 2, and then the drive shaft 41 is installed to the middle of the positioning platform 22, while driving the rotor assembly 5 to be installed to the middle of the stator assembly 3, and then the entire drive component is integrated and installed in the drive cavity 2, so that the overall structure is relatively compact, thereby reducing the space required for installation, and by arranging a control panel 8 between the pressure cover 6 and the cover plate 7, the control panel 8 is further reduced, and the number of wire connections between the internal parts of the motor is simplified, so that the interior of the motor is simplified, which is conducive to further heat dissipation of the motor. At the same time, by reducing the number of wire connections, the probability of motor failure due to loose bolts at the fixing points of the wire ends can be further reduced, thereby improving the reliability and practicality of the device.
