[0021] Please see Figure 1 This utility model embodiment: A docking servo encoder motor includes: a main shaft 1, a first cover 2, an aluminum wheel 3, and a second cover 4 disposed on the main shaft. The first cover, aluminum wheel, and second cover are docked together to form the main housing of the motor. The first cover, aluminum wheel, and second cover are provided with corresponding threaded holes on their circumference and end faces. The first cover and aluminum wheel are detachably connected by screws passing through the corresponding threaded holes. The aluminum wheel and second cover are also detachably connected by screws passing through the corresponding threaded holes. A countersunk head screw is selected, and the screw head can be flush with the circumference of the first cover, aluminum wheel, and second cover, which is both aesthetically pleasing and effectively prevents the motor from detaching, ensuring impact protection.

[0022] Specifically, the main shaft is sequentially fitted with an iron core 5, a rotor housing 6, a central wheel 7, a bracket 8, and an encoder base 9. An encoder 10 is mounted on the encoder base. An aluminum cover 11 is installed outside the aluminum wheel, and a signal magnetic ring 12 that works in conjunction with the encoder is installed inside the aluminum cover. A magnet 13 is installed between the iron core and the rotor housing, and a third bearing 14 is installed between the rotor housing and the main shaft. A nylon wheel 16 is connected to the bracket via a support column. An internal gear ring 15 is installed outside the nylon wheel, meshing with the nylon wheel. The nylon wheel meshes with the central wheel to achieve motor deceleration. The central sensing areas of the encoder and the signal magnetic ring are on the same horizontal axis. The encoder typically works with a Hall plate, a PCB board, and other necessary electronic components. The Hall plate senses changes in the magnetic field and converts them into electrical signals. These signals are processed and amplified by the circuitry on the PCB board, ultimately outputting a signal representing the rotational position. This allows for the detection of rotational speed information, enabling timely shutdown and safety protection.

[0023] Specifically, the main shaft uses a predetermined material and undergoes a special heat treatment process to stabilize its strength, ensuring that it will not break or wear under high-intensity operation of the motor, thus affecting the motor's performance.

[0025] Specifically, the first cover is mounted on the main shaft via the first bearing 24, the aluminum wheel is mounted on the main shaft via the second bearing 25, and the iron core is wound in a specific manner to ensure that the motor temperature rise will not be too high, so that the motor can reach the rated speed and ensure the motor life.

[0026] Specifically, a flange 26 is provided on the outside of the first cover on the main shaft. The flange is connected to the main shaft through a shaft snap ring 27, which can effectively limit the axial movement of the motor and limit the axial movement of the flange without affecting the strength. A C-key 28 is provided between the bracket and the main shaft to facilitate the fixed installation of the main shaft and the bracket.
