Benefits :

Some of the advantages of permanent magnet stepper motor are:

  • It needs minimum power to work.
  • Compared with variable reluctance motor, permanent magnet stepper motor provides increased cogging torque There are no additional circuitry requirements for rotor operation.
  • For every amp of stator current, a high torque is produced.
  • Shows better response for stop, start and reverse operations. Since there are no contact brushes in this motor, it offers increased reliability.
  • When the windings are energized, the motor will have full torque at standstill.

Application :

  • printers.
  • CNC-equipment.
  • 3D printers.
  • lasers.
  • manipulators.
