Abstract
A speed control method for an SR motor using a load with a large mechanical inertia that performs a PWM in an acceleration state wherein a speed of the motor radically changes and switches an inverter transistor for a previously determined time in a steady state wherein the speed thereof becomes an uniform level, thereby regularly fixing a time for which a current flows to motor coils connected with the switching transistor.
