The paper discussed a design and development of the switched reluctance motor with ADMC as DSP motor controller. With a study on the basic principle and control method of the switched reluctance motor, in combined with resources and function of ADMC, software of the controller was designed. Reaching at the certain technical requirements and performance indexes, a flexible control of start, brake, speed or other operational mode can be made to the switched reluctance motor. It has a quick speed in calculation. The motor controller has a well outlet connected equipment with a special switched reluctance control element. Those have obvious advantages to the control of the switched reluctance motor.
