ABSTRACT:
Disclosed is a method and apparatus for controlling current in a switched reluctance motor (SRM), in which after measuring the rotating speed of the SRM and determining whether the motor is decelerated or accelerated, current signals each having a waveform suitable to the acceleration/deceleration and the rotating speed of the motor are read from a current waveform table of a memory and then transmitted, and the current signals are controlled and then transmitted to motor coils of each phase, thereby driving the motor.
