[0004] There is no anti-loosening structure. After the equipment has been used for a long time, due to the physical characteristics of thermal expansion and contraction, a small gap will be generated between the armature shaft and the rotor core, which will cause the rotor core to slip and loosen, resulting in damage.

[0024] 3. By setting the outer surface of the first anti-slip sheet to a rough structure, the device can form a clutch structure with the second anti-slip sheet. The friction force makes the first anti-slip sheet fit better and prevents it from rotating and loosening. In addition, six grooves are provided on the outer side of the center of the first anti-slip sheet to provide a larger heat dissipation surface for the device, thereby improving the heat dissipation capacity of the device.

[0025] 4. By making the first anti-slip sheet into a flat structure, the device can provide sufficient support force and contact area when it is attached to the second anti-slip sheet, effectively increasing the friction between the first anti-slip sheet and the second anti-slip sheet;

[0026] 5. The device fixes a nail block at the edge of the first anti-slip plate groove, and the length of the nail block is flush with the depth of the groove, which can limit the positioning bolt and prevent the positioning bolt from shifting and failing to align with the through hole opened at the midpoint of the first anti-slip plate groove;

[0027] 6. The device fixes a D-shaped block on the right side of the positioning bolt. When the first anti-slip sheet and the second anti-slip sheet are in contact, the arc surface of the first anti-slip sheet will gradually decrease, and at the same time, the groove on the side of the first anti-slip sheet will gradually expand. Under the action of the spring, the positioning bolt can be pushed inward and contact the rotor rod groove to provide a limiting effect.
