What are the types of electric motors for new energy vehicles? (1)

New energy vehicle motors, permanent magnet synchronous motors, and brushless motors are gradually replacing traditional fuel vehicles as the "main force" of future automobiles with the development of society. As the main source of power for new energy vehicles, the importance of driving motors is self-evident. So, what are the types of motors for new energy vehicles? At present, there are three main types of new energy vehicle motors used in the market: permanent magnet synchronous motors, AC asynchronous motors, and switched reluctance motors.

1、 Permanent magnet synchronous motors are widely used in the field of new energy vehicles. A permanent magnet synchronous motor is a synchronous motor that is excited by a permanent magnet and has a sinusoidal current. The advantages of permanent magnet synchronous motors are high driving efficiency, high torque, high power density, small size, light weight, and no excitation loss and heat dissipation issues. But its drawbacks are also obvious: complex control during high-speed operation, demagnetization of permanent magnets, and high motor cost. Therefore, permanent magnet synchronous motors are mainly used in the field of electric passenger vehicles with high requirements. Compared with other types of motors, the major advantage of permanent magnet synchronous motors is that they have higher power density and torque density. Compared with other types of motors, permanent magnet synchronous motors can provide greater power output and acceleration for new energy vehicles under the same mass and volume. This is also the main reason why permanent magnet synchronous motors have become the primary choice in the new energy vehicle industry, which requires high space and weight requirements.

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.
