Variable Reluctance Type (VR type) Stepper Motor

This type of motor consists of a soft iron multi-toothed rotor and a wound stator. When the stator windings are energized with DC current the poles become magnetized. Rotation occurs when the rotor teeth are attracted to the energized stator poles. This motor has poor torque load characteristics, rather than the motor types discussed below, hence have a low scope of applications compared to Permanent magnet and Hybrid types
