Stepper Motor and its applications

Stepper Motor

Stepper motor is an electromechanical special device that can rotate fixed angular steps when any digital input is applied. It is very suitable for precise position, speed, direction, control etc which are very required in automation system.

Applications for stepper motor

  • Instrumentation
  • Computer peripherals
  • Machine drives etc.

Stepper motor is used in floppy drives, dot-matrix printers, X-Y plotters, digital watches etc. The step size of a stepper motor varies from 0.9 degrees to 30 degrees. The angle x may be calculated as x = 360 degree/no. of rotor teeth.
