What are the requirements for drive motors for new energy vehicles?

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.

01. Lightweight and small in size

The demand for lightweight and effective space in new energy vehicles requires the drive motor to be lightweight and small in size while meeting the requirements, reducing the curb weight of the vehicle and contributing to the power and endurance of the vehicle.

02. Long lifespan and high reliability

As the core component of a car, the drive motor must meet the requirements for dust, water, and shock resistance, and its lifespan and reliability must be the same as the entire vehicle. There will be basically no problems throughout the entire life cycle of the car.

03. High voltage resistance

Within the allowable range, high voltage should be used as much as possible to reduce the size of the motor and the size of equipment such as wires, especially to lower the cost of the inverter.

04. High efficiency across the entire speed range

In order to ensure a long driving range, the drive motor should operate as efficiently as possible throughout the entire speed range, especially in complex road conditions and frequent changes in driving mode. Low load operation should also have high efficiency.

05. Low speed high torque characteristics and wide range constant power characteristics

The driving motor should have the torque characteristics required for car operation, meeting the power and torque requirements for starting, accelerating, driving, decelerating, braking, etc.

06. Safety of Electrical Systems

At present, the working voltage of new energy vehicles on the market is generally above 300V, and the safety of the electrical system, including the motor, must comply with relevant safety performance standards and regulations for vehicle electrical control.
