Abstract
Permanent magnets are interposed within the circumferential spaces between the circumferentially spaced pole pieces of the stator of a variable reluctance step motor. The magnets are magnetized in a circumferential direction and serve to increase the dynamic and holding torque characteristics of the motor while providing the motor with detenting torque and while dampening overshoot and oscillation of the rotor of the motor as the rotor arrives at and settles into its detent positions.
