Do you understand the core of new energy vehicle motors?

At present, there are two main types of motors used in new energy vehicles on the market: permanent magnet synchronous motors and AC asynchronous motors. New energy vehicles include pure electric vehicles, extended range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

As the power source of new energy vehicles, the quality of electric motors determines how far new energy vehicles can go. In addition, with the development of electric vehicles in recent years, the importance of electric motors is self-evident. At present, there are two main types of motors used in new energy vehicles on the market: permanent magnet synchronous motors and AC asynchronous motors.

The working principle of permanent magnet synchronous motors is to generate magnetism through electricity. After being powered on, the coils in the motor will generate a magnetic field, and then the coils will start to rotate because the internal magnets repel each other. The greater the current, the faster the coil rotates.

The advantage of using permanent magnet synchronous motors lies in their small size and light weight, which can save a lot of space; In addition, the efficiency of permanent magnet synchronous motors is excellent, and their high power density can achieve a working efficiency of 97%, which ensures power and acceleration for automobiles. However, the disadvantage of permanent magnet synchronous motors is that they are expensive and require the use of rare earth resources as materials.

As is well known, China is a country with a large amount of rare earth storage in the world, and the total production of magnetic materials in China also reaches 80% of the world.
