When the motor runs, the rotor core rotates to drive the rotor shaft to rotate through the rotation of the rotor, the rotor shaft drives the fan blades to rotate, so that air outside the motor flows through the air inlet holes to be in contact with the rotor and flows out of the motor through the air outlet holes, the air outside the motor continuously flows into and out of the motor, the contact area of the air and the rotor is increased, the air continuously cools the rotor, and the motor is efficiently and continuously cooled.

Preferably, a plurality of heat dissipation plates are distributed on the circumference of the end face of one end, which is not adjacent to the fan blades, of the rotor iron core, and the heat dissipation plates are coplanar with the axis of the rotor iron core, so that the rotor iron core drives the heat dissipation plates to rotate together in the rotating process, and the flowing speed of air is increased.

Preferably, the air inlets are distributed on the end face of the rear end cover at intervals in an annular shape, and extend to the wall body of the rear end cover, so that the area of the air inlets is increased, and the air circulation is enhanced.

Preferably, the air outlet holes are distributed on the circumferential surface of the front end cover at intervals in a ring shape, and the air outlet holes extend to the wall body of the front end cover, so that the area of the air outlet holes is increased, and the flowability of air is enhanced.

Preferably, the fan blade is a structure with one side concave and the other side convex, so that the air flow driven by the rotation of the fan blade is enhanced.

Preferably, the front end cover and the rear end cover are fixedly connected to the shell through fasteners, positioning grooves for positioning the front end cover and the rear end cover are formed in the two ends of the shell, the motor can be conveniently disassembled and maintained, meanwhile, the large rear end cover can be conveniently replaced, and accordingly air at the fan blades can flow better.

Preferably, a first punching rib tightly matched with the rotor iron core is arranged on the rotor shaft, and a second punching rib tightly matched with the fan blade is arranged on the rotor shaft, so that the fan blade and the rotor iron core are stably fixed on the rotor shaft.

The utility model has the advantages that: the contact area of the rotor inside the motor and air can be increased, the radiating effect of the motor is enhanced, and the motor can be efficiently radiated.
