The layout of the heat absorption pipe 7 enables the cooling liquid to effectively absorb heat of key parts of the stator 2, ensures uniform temperature distribution in the whole motor, and the heat dissipation pipe 8 and the heat dissipation fins 9 can rapidly conduct heat generated in the motor to the outside, so that the motor is prevented from overheating, and the working efficiency and the reliability are improved.
In this embodiment, a circular hole is formed in the rear seat 6, a fan blade 11 is disposed in the circular hole, the rotating shaft 4 is fixed to the center of the fan blade 11, and the heat sink 9 is fixed to the inner wall of the circular hole. The fan blades 11 enable air to enter the gaps of the cooling fins 9 through the round holes when the motor works, so that air flow is enhanced, and the cooling effect is improved.
In this embodiment, the fixing frame in the rear seat 6 is provided with a guide cover 12, the inner wall of the guide cover 12 is communicated with the inside of the housing 1, and the outer wall of the guide cover 12 is connected to the outside of the housing 1. That is, the air guide cover 12 can guide the air flow generated by the fan blades 11 to the inside and outside of the housing 1, so as to dissipate heat in the housing 1 and the heat sink 9, respectively.
In this embodiment, the air outlet holes are distributed in the side wall of the housing 1. So that the air flow from the pod 12 into the housing 1 can be exhausted.
In this embodiment, a guide cone 13 is disposed in the guide shell 12, and the guide cone 13 is rotatably and slidably sleeved in the rotating shaft 4.

The rotary shaft 4 of the guide cone 13 can be driven to slide by moving the pull rod 14, when the guide cone 13 is far away from the guide cover 12, the gap between the guide cone 13 and the guide cover 12 is increased, so that the air flow entering the inside of the shell 1 is increased, the heat dissipation effect on the rotor is enhanced, and the motor is suitable for the working condition of low torque and high rotation of the motor; when the diversion cone 13 is close to the diversion cover 12, the gap between the diversion cone 13 and the diversion cover 12 is reduced, so that the air flow entering the inside of the shell 1 is reduced, the air flow flowing to the outside of the shell 1 is increased, and the heat dissipation effect on the heat dissipation fins 9 is enhanced so as to adapt to the working condition of high torque and low rotation of the motor.
