At a Glance: Stepper Motor

A stepper motor divides a full rotation into a number of discrete steps. The motor's position can then be commanded to move and hold at one of these steps. Once stopped, the stepper holds the load steady with a holding torque. Most stepper motors employ a doubly salient design with teeth on both the rotor and stator structures. Like a brushless DC or permanent magnet synchronous motor, the permanent magnets are on the rotor and the electromagnets are in the stator.

Key Characteristics

  • Inexpensive: the rotor contains no winding slip rings or commutator
  • Easy to position: moves in steps based on pulses supplied to the stator windings
  • Direction of rotation changes by reversing the pulse sequence
  • Speed control through frequency of pulses or pulse rate
