New Energy Vehicle Drive Motor

The permanent magnet motor drive system can be divided into a brushless DC motor (BLD-CM) system and a permanent magnet synchronous motor (PMSM) system. 

A permanent magnet synchronous motor (PMSM) system has the characteristics of high control accuracy, high torque density, good torque smoothness, and low noise, 

and through the reasonable design of the permanent magnet magnetic circuit structure can obtain high weak magnetic properties and improve the speed regulation range of the motor 

Battery, motor, and electronic control are the three core components of new energy vehicles.

The motor drive control system is the main executive structure of new energy vehicle driving, and its driving characteristics determine the main performance index of vehicle driving.

The motor principle can be divided into synchronous motor and asynchronous motor, synchronous motor according to the magnetic field is not the same, there are permanent magnet synchronous motor, hysteresis synchronous motor, and reluctance synchronous motor. The so-called synchronous asynchronous refers to the rotor speed and magnetic field rotation speed is the same, the speed of the same is called synchronous, the speed is not the same and is called asynchronous.

Tolerance control is quite important for magnet application
