Hybrid stepper motor is a combination of variable reluctance and permanent magnet motor. The stator is electromagnetically stimulated like variable reluctance stepper motor, and the rotor of the stepper motor is axially magnetized like permanent magnet stepper motor. This stepper motor is an actuator that converts electrical pulses into angular displacement.
