[0002] The motor in the paper shredder is the core component of the product, which drives the operation of the entire paper shredder, but it is easy to be damaged by mechanical stress and thermal stress, which can be caused by frequent start-up, overload, blockage, and long-time operation. The source of thermal stress is the thermal effect of motor current, and mechanical stress can be understood as the operation of the motor, both of which can cause the motor to heat up. When the core component of the product heats up, it will affect the performance of the entire product, and over time, the damage to the product is inevitable.

[0003] The existing motor for driving the operation of the paper shredder core is usually provided in the head cover, and the two ends of the motor are respectively provided with an output shaft for driving the core and an output shaft for installing the fan blade. When the motor drives the operation of the paper shredder core, the blades rotate synchronously to dissipate heat from the motor. In order to enhance the heat dissipation effect, a plurality of air cooling components are usually provided on the head cover where the motor is located, that is, a plurality of ventilation holes are provided on the head cover corresponding to the motor part, and each ventilation hole is provided with an independently operated air cooling component.
