What is the working principle of the drive motor?

The direct current of the power battery passes through the high-voltage distribution box and is converted into alternating current through the DC/AC converter in the motor controller, which is provided to the permanent magnet synchronous motor to drive the vehicle.

When the vehicle is coasting or braking, the motor controller controls the driving motor to be in a power generation state. The driving motor utilizes the vehicle's kinetic energy to generate electricity. The three-phase AC power is rectified into DC power through the AC/DC converter in the motor controller, and the recovered energy is stored in the power battery.

To avoid excessive temperature during the operation of the drive motor, the coolant in the motor cooling circulating water pipe can take away excess heat and keep it within the normal operating temperature range.

As a national high-tech enterprise integrating motor research and development, manufacturing, and sales, Jiangkou Electric Appliance Manufacturing Co., Ltd. has an extraordinary pursuit of motors. The product not only covers commonly used industrial and commercial motor projects such as DC permanent magnet motors, AC series excited motors, brushless motors, gear reduction motors, but is also widely used in variable speed gear selection/braking systems and other components of new energy vehicles, general commercial and passenger vehicles, office/home furniture, medical and health automatic equipment, household appliances, professional electric tools, electric/automatic door opening equipment, and other aspects.
