What kind of stepper motor? What's the difference? Published On :2017-05-21Views :
Stepper motor is divided into three kinds: permanent magnet (PM), reactive (VR) and hybrid (HB)Permanent magnet step is generally two-phase, torque and volume is small, the stepping angle is generally 7.5 degrees or 15 degrees;
Reaction step is generally three-phase, can achieve large torque output, step angle is generally 1.5 degrees, but the noise and vibration are great. In Europe and the United States and other developed countries 80 years have been eliminated.
The mixed step is the advantage of mixing the permanent magnet and the reactive. It is divided into two-phase four-phase and five-phase: two-step steep angle is generally 1.8 degrees and five-step steep angle is generally 0.72 degrees. This stepper motor is the most widely used.
