Advantages Of Stepper Motors

Mar 16, 2017
  • 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 energized)

  • 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 realized as the speed is proportional to the frequency of the input pulses.
