PMSM Motor Used for Electric Vehicle

Introduction
 

Permanent magnet motor is a kind of synchronous motor. Its rotor uses permanent magnet. The stator generates electromagnetic torque to drive the magnetic field of the rotor to rotate around the axis. The magnetic fields of the stator and rotor are synchronous. Permanent magnet synchronous motor is widely used in domestic electric vehicles.

Structure

• Permanent magnet synchronous motor itself has high power efficiency and high power factor;
• Permanent magnet synchronous motor has small heating, so the motor cooling system has the advantages of simple structure, small volume and low noise;
• The system adopts fully enclosed structure, without transmission gear wear, transmission gear noise, lubricating oil and maintenance;
• Permanent magnet synchronous motor allows large overload current and significantly improves its reliability;
• The weight of the whole transmission system is light, the unsprung weight is lighter than that of the traditional axle transmission, and the power per unit weight is large;
