The right middle of the motor body 1 is connected with the fan 108, the right side of the ventilation plate 102 is provided with a ventilation hole, and the heat dissipation plate 107 is circumferentially arranged around the fan 108. The fan 108, the circular hole in the middle of the controller 104, and the ventilation plate 102 are located on the same axis, and the fan 108 is connected with the right end of the rotating shaft in the motor body 1.

[0030] Through the arrangement of the cooling structure, the fan 108 rotates, air enters through the air inlet hole of the ventilation plate 102, the controller 104 is cooled, a through hole is formed in the center of the circuit board of the controller 104, air passes through the through hole, then passes through the shell of the controller 104, a through hole is formed in the middle of the heat dissipation plate 107 to blow to the heat dissipation plate, and the motor body 1 is cooled through the wind guide cover 109 and the wind guide plate 110.
