Abstract :
The major disadvantage of a chopper-driven step motor is its poor damping characteristics. The causes of poor damping are investigated, and the effects of various motor parameters on damping are discussed. A simple circuit to improve the damping response of the step motor is proposed. Results obtained from computer simulations are presented
