Problems solved by technology
[0002] The motor has a wide range of uses, and the working environment is complex. Some of them need to be waterproof and dustproof. The rotor and stator of the motor need to be closed to work. When the motor is working, it generates heat due to its own energy consumption, and the friction and heat conduction with other related machinery increase the working temperature of the motor. , especially during overload operation, a large amount of heat energy is generated. If the heat is not cooled in time, the efficiency of the motor will be low, or even damaged.

Embodiment Construction
[0007] The motor cooling system and its working method are, as attached figure 1 , Introduce the intake pipe 3 and the exhaust pipe 4 into the inner stator shaft tube 8, respectively into the motor cavity, set the fan blade 6 on the outer rotor 2, when the outer rotor 2 drives the fan blade 6 to rotate, the air is sucked from the intake pipe 3, Air passes through the filter 5 and enters the coil gap between the motor cavity and the inner stator 1 through the intake pipe 3 , and the airflow is discharged from the exhaust pipe 4 under pressure. Certainly also can increase tool other booster intake and exhaust device on the intake and exhaust pipeline.
[0008] Another embodiment of the motor heat dissipation system and its working method is as attached figure 2 , as shown: the inlet pipe 3 and the exhaust pipe 4 are introduced on the end wall of the outer stator 1, respectively introduced into the motor cavity, and the fan blade 6 is set on the inner rotor 2. When the inner ro...

A heat dissipation device for an electric motor: an air intake pipe and an exhaust pipe are installed on the stator of the electric motor, and fan blades are arranged on the rotor. A filter is arranged at the inlet of the air intake pipe to filter the passing air or impurities in the heat transfer liquid. An auxiliary circulation pump or fan blade is installed on the exhaust pipe, and a radiator is installed on the heat dissipation circulation pipeline outside the motor cavity to increase the efficiency of heat conduction circulation. The beneficial effect brought by the adoption of the above technology is: the inlet pipe and the exhaust pipe can be far away from the working environment of the motor, and can be used for air heat conduction to prevent dust and water; The heat in the motor cavity can be quickly circulated to the outside of the motor to achieve the purpose of quickly dissipating heat for the motor.
Description
Technical field: [0001] The invention relates to the technical field of motor heat dissipation. technical background: [0002] The motor has a wide range of uses, and the working environment is complex. Some of them need to be waterproof and dustproof. The rotor and stator of the motor need to be closed to work. When the motor is working, it generates heat due to its own energy consumption, and the friction and heat conduction with other related machinery increase the working temperature of the motor. , especially during overload operation, a large amount of heat energy is generated. If the heat is not cooled in time, the motor will be inefficient or even damaged. In particular, the hub motors used in electric vehicles must be waterproof and dustproof. The brakes on the hubs generate high heat when braking, and the permanent magnet motors will demagnetize due to high heat. This is also the main problem that is difficult to promote in-wheel motors in the industry. Invention...
