• A stepper motor is a machine where the motor turns indistinct movement and is called the steps. It lacks the requirement of rotating continuously which is similar to a conventional motor.
  • The stepper motor is also called an extraordinary variety of synchronous motor which is specially intended to turnover a limited number of degrees for each electrical pulse acknowledged by its own control unit.

Characteristic steps are 2°, 2.5°, 5°, 7.5° and 15° per pulse. However, these motors are constructed in such a way that it follows signals as rapid as 1200 pulses per second corresponding to some comparable power ratings upto several kW.

  • The stepper motor is applied to a digitally organized location regulatory system that too in an open loop mode.

A train of pulses which abides by the input commands and operations makes shaft turn over a specified angle.
