Classification Of The Stepping Motor
Ningbo Minsheng Machinery Co.,Ltd | Updated: Sep 14, 2016

Stepper motor divided into three types: permanent magnet (PM), response (VR) and hybrid (HB). Permanent magnet stepper for two-phase, torque and smaller step angle is 7.5 or 15 degrees; General for three-phase reaction stepper can realize high torque output, step angle of 1.5 degrees, but the noise and vibration are large. In Europe and other developed countries 80 have been eliminated; hybrid step refers to a mixture of permanent magnet type and reaction advantages. It is divided into two phases and five-phase: two step angle 1.8 degrees and five phase step angle of 0.72 degrees. The most widely used stepper motors.

Stepper motor temperature too high at the outset will make motor demagnetization of magnetic materials, resulting in a moment fall out of step, so motor exterior allows the maximum temperature depends on motor demagnetization of magnetic materials; in General, demagnetization in magnetic materials are above 130 degrees Celsius, some even as high as more than 200 degrees Celsius, temperature in 80-90 stepper motor looks completely normal.
