Motor shell with electromagnetic radiation prevention and heat dissipation functions

The utility model provides a motor housing with electromagnetic radiation prevention and heat dissipation functions. The motor housing comprises a heat dissipation housing and a radiation protection cover. A plurality of grooves are formed in the outer wall of the heat dissipation shell in the circumferential direction at intervals, a metal rubber block is detachably connected into each groove in an inserted mode, and a heat conduction silicone grease coating is arranged on the inner wall of the heat dissipation shell. The radiation protection cover is detachably arranged outside the heat dissipation shell in a sleeving mode, the radiation protection cover comprises a steel plate layer, an electromagnetic protection coating is arranged in the steel plate layer, and an anti-static coating is arranged in the electromagnetic protection coating. According to the motor shell with the electromagnetic radiation prevention and heat dissipation functions, heat generated by operation of the motor is dissipated through
