Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and more specifically, to an automobile driving motor. Background Art

[0002] In the existing technology, the automobile drive motor is usually directly installed on the car, which results in the heat generated by the drive motor operation not being effectively dissipated. This situation causes the heat to be transferred to the motor controller, thereby affecting the heat dissipation effect of the controller. Due to the lack of effective heat dissipation methods, the temperature of the motor and controller may increase, reducing their working efficiency and lifespan;

[0003] At present, cable ties are commonly used to bind three-phase wires in automobile drive motors. However, the service life of cable ties is short. Once the cable ties break, the three-phase wires will lose their fixation and easily wear out. Since the three-phase wires carry high voltage electricity when working, once they wear out, the wires will be exposed, posing serious safety hazards.

[0004] Existing automotive drive motors usually expose the drive shaft to the outside, which makes the precision parts inside the motor vulnerable to the intrusion of dust and debris. Since the motor is a long-term device, the accumulation of dust may lead to accelerated aging of internal parts and even affect the normal operation of the motor. Therefore, it is very important to keep the drive motor clean and dust-proof. Utility Model Content
