This design makes the disc motor small in size, light in weight, compact in structure, and efficient in heat dissipation. The working principle of the disc motor is similar to that of the traditional motor, which uses a rotating magnetic field to generate torque. However, its unique structure makes it have unique advantages in certain application scenarios, such as the cooling fan drive of electronic products, and has broad application prospects. As disclosed in notification number (CN118381276A), a coreless ultra-thin axial motor rotor structure, stator structure and motor are disclosed, belonging to the technical field of disc motors, and include a shaft rod, on which an upper rotor disk and a lower rotor disk are fixedly mounted, respectively; balls are rotatably mounted in a circumferential array near the edge on one side opposite to the upper rotor disk and the lower rotor disk, and a coil is mounted in a circumferential array on the stator disk; arc grooves of circular ring structure are provided on the outer sides of the upper and lower surfaces of the stator disk; by adopting balls, when the rotor structure and the stator structure rotate relative to each other, the balls support the air gap in the middle to prevent the rotor structure from generating polarization during operation; and through the oil storage tank and the oil hole, during the rotation, the balls are filled with lubricating grease by centrifugal force to improve the stability of the operation; and through the center bearing, the lower bearing and the upper bearing, the stability of the shaft rod during rotation is further improved, thereby improving the service life.

An adjustment component 7 is installed in the lower shell 2. The adjustment component One end of the component 7 is connected to the circular connecting plate 4. The adjustment component 7 is used to adjust the lower rotor disk 6 to the central position in the lower shell 2. Through the adjustment component 7, the lower rotor disk 6 is rotated at the center position of the motor as a whole, so that the rotation of the output shaft 14 is more stable and abnormal noise is avoided. An annular adjustment groove is opened at the bottom of the lower shell 2, and a position-adjustable fixed connection component 8 is installed in the annular adjustment groove. The position of the position-adjustable fixed connection component 8 in the annular adjustment groove can be adjusted as needed to achieve specific connection or fixing functions to meet different installation requirements.

[0029] An upper rotor disk 9 and a stator disk 10 are installed inside the upper shell 1. The upper rotor disk 9 is rotatably connected to the upper shell 1 through a bearing 11.

When in use, the stator winding 13 is energized, so that the rotor poles 12 drive the upper rotor disk 9 and the lower rotor disk 6 to rotate, so as to drive the output shaft 14 to rotate, thereby starting the motor. When in use, the overall thickness between the upper shell 1 and the lower shell 2 is 8.89 mm, and the overall diameter of the motor is 33.14 mm, which is more compact and lightweight, and is suitable for driving fans in smaller electronic products.

[0030] The snap-on connector 3 includes a first annular connecting block 301 and a second annular connecting block 302, which are respectively sleeved on the upper shell 1 and the lower shell 2, and a ring-shaped snap-on block 303 is fixedly installed on the first annular connecting block 301, and the ring-shaped snap-on block 303 is inserted into an embedding groove provided on the second annular connecting block 302.

A driving pull rod 805 is fixedly installed on the embedded block 804. A limit pin 806 is fixedly installed on the other end of the movable push plate 803. The limit pin 806 is inserted into the limit pin holes correspondingly provided on the arc-shaped slider 801 and the lower shell 2. In the embodiment, the movable push plate 803 is elastically connected to the arc-shaped slider 801 through the positioning spring 807. When in use, the arc-shaped slider 801 is controlled to slide in the annular adjustment groove to facilitate the adjustment of the position of the fixed connection block 802. The overall installation of the motor is achieved through the fixed connection block 802. When the position of the fixed connection block 802 is adjusted, it is convenient to meet different installation positions and is more flexible to use. After the arc-shaped slider 801 is adjusted to a certain position, under the action of the positioning spring 807, the movable push plate 803 drives the limit pin 806 to be fixedly inserted in the limit pin hole, so as to facilitate the positioning of the fixed connection block 802.
