The stepper motor is divided into three types: permanent magnet (PM), reactive (VR) and mixed type(HB)

Permanent magnet stepper usually two-phase, torque and smaller step angle, usually 7.5 or 15 degrees;

The reaction is generally three-phase stepper, can achieve high torque output, the step angle is generally 1.5 degrees, but the noise and vibration are large. In Europe and other developed countries have been eliminated in 80.

Hybrid step is a mixture of the advantages of permanent magnet type and reaction type. It consists of two phases: phase four phase and five phase step angle of 1.8 degrees while the general five phase step angle of 0.72 degrees is generally. The application of the stepper motor is the most widely.
