[0002] A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. When a motor converts energy, a small amount of loss is always converted into heat. It must continuously dissipate the heat to ensure the normal operation of the motor and reduce damage to surrounding components.

[0003] An existing motor heat dissipation method is to install a fan at the end of the motor to dissipate the heat of the motor. However, with this heat dissipation method, a large amount of dust will accumulate at the fan end during long-term use. When removing the dust, the motor casing needs to be completely dismantled before the fan can be dusted. Professional demolition personnel are required to complete the tedious demolition process, which increases the difficulty of cleaning and also takes a long time to dismantle. Utility Model Content
