Description

technical field [0001] The present invention relates to the technical field of motors, and more particularly, the present invention relates to an integrated integrated motor system. Background technique [0002] The core of the pure electric vehicle power system is the motor and the motor controller. The function of the motor controller is to control the electric vehicle by converting the electric energy stored in the power battery into the electric energy required to drive the motor according to commands such as gear, accelerator, and brake. It can also help the electric vehicle to brake, and store part of the braking energy in the power battery. Electric vehicles have experienced more than 10 years of development in China. The cooling structure of its power motor is transformed from an industrial motor: the power output shaft of the motor is drawn from both ends, and the power output shaft at one end of the motor is used as the driving shaft output of the driving power of ...

Problems solved by technology

[0003] However, such a cooling structure becomes a decoration for a vehicle drive motor that requires full speed, full torque, and full power operation, and even becomes a burden that basically only consumes energy; when the motor is running at high speed, there is Higher efficiency, the heat of the motor is not serious, and the demand for forced air cooling is not great, but at this time the cooling fan rotates at a high speed, wasting energy in vain; when the vehicle is driving with a heavy load, the speed of the motor is reduced The load pulls slowly, the heavier the load, the slower the motor speed, and the more serious the heat generation. At this time, there is a higher demand for forced air cooling, but because the cooling fan of the motor is connected to the power output shaft of the motor, the motor will not be affected by the forced air cooling. When the demand for air cooling is high, the fan speed will slow down instead. The heavier the vehicle load, the higher the requirement for forced air cooling. At this time, the slower the cooling fan rotates, the less cooling air the cooling fan can provide.

The cooling structure composed of such a cooling fan cannot meet the cooling requirements of the electric vehicle drive motor at all.

[0004] Affected by traditional concepts in the current field of electric tricycles, almost no mass-produced electric tricycle drive motor controller is equipped with a forced cooling mechanism, all of which are naturally cooled

However, in the field of electric tricycles, when the load of the vehicle is large, the heating of the drive motor controller is very serious

The actual situation is: From the technical point of view of the product, it is necessary to install a forced cooling mechanism for the drive motor controller, but from the perspective of product manufacturers and users, it is still unacceptable to install a forced cooling mechanism for the drive motor controller. mechanism, leading to a high failure rate of the drive motor controller
