With a trapezoidal back-EMF permanent magnet synchronous motor is often referred to as brushless DC motor, it has a simple structure, small size, light weight, high efficiency, high power density, starting torque, inertia, and other types of fast response dc can not match the characteristics of the motor. Electronic commutator DC motor instead of the traditional mechanical reversing device, thereby overcoming the brushes and commutator caused by noise, sparks, electromagnetic interference, short life and a series of ills.
