What kinds of driving motors are there for electric vehicles?

DC motor, AC motor, permanent magnet synchronous motor, AC asynchronous motor and so on. Although the asynchronous motor has low cost and convenient maintenance, it has low efficiency and poor speed regulation. Only a few models have been selected, but there are also many mainstream models. At present, this kind of motor will not become a trend. The structure of permanent magnet synchronous motor is similar to DC motor.

Through the mode, the invention has the characteristics of simple structure, reliable operation, high power density and good speed regulation performance. At the same time, because the driving mode of permanent magnet synchronous motor is different from that of DC motor, permanent magnet synchronous motor is superior in noise and control.

Main advantages:

As long as the motor is directly driven by high-power triode or field effect transistor or relay, when the motor needs bidirectional rotation, H-bridge circuit or double-pole double-throw relay composed of four power elements can be used.

If you don't need speed regulation, use a relay; However, if speed regulation is needed, switching elements such as triode and field effect transistor can be used to realize PWM (pulse width modulation) speed regulation.
