  • Supreme finish
  • Smooth surface
  • Long lasting life
  • Low cost for control achieved
  • High torque at startup and low speeds
  • Ruggedness
  • Simplicity of construction
  • Can operate in an open loop control system
  • Low maintenance
  • Less likely to stall or slip
  • Will work in any environment
  • Can be used in robotics in a wide scale.
  • High reliability
  • The rotation angle of the motor is proportional to the input pulse.
  • The motor has full torque at standstill (if the windings are energised)
  • Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3 – 5% of a step and this error is non-cumulative from one step to the next.
  • Excellent response to starting/stopping/reversing.
  • Very reliable since there are no contact brushes in the motor. Therefore, the life of the motor is simply dependent on the life of the bearing.
  • The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
  • It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
  • A wide range of rotational speeds can be realised as the speed is proportional to the frequency of the input pulses.
