The main body part of the motor is arranged in the motor mounting shell 20, and the generated heat is guided out by the second radiating fins 21 along the direction of the motor mounting shell 20, is radiated to the shell 10 and is guided out by the first radiating fins 11 of the shell 10; the heat generated by the circuit in the circuit mounting case 30 is conducted out by the third heat dissipation fins 31, dissipated to the housing 10, and then conducted out by the first heat dissipation fins 11 of the housing 10 and the second heat dissipation fins 21 of the motor mounting case 20, thereby realizing efficient dissipation of heat and ensuring heat dissipation effect. Because the heat dissipation part and the circuit part are arranged integrally with the shell, the volume of the whole machine shell is reduced, the occupied area of the machine shell and the motor is smaller, and the machine shell and the motor are more convenient to install and use; due to the high integration, the weight is also light.

In one embodiment, the cross section of the housing 10 is quadrilateral and the corners are smoothly arranged. The motor mounting case 20 is formed in a cylindrical shape as a whole, and is disposed toward the extending direction of the first heat radiation fins 11.
