<p>A switched reluctance motor driving circuit allows the speed of the motor to be controlled by adjusting the dc supply voltage applied to the stator coil switching circuit (50). As a result, none of the switching elements (Q1,..., Q6) of the switching circuit need be switched other than directly in response to rotor position. The dc voltage may be chopping ac mains using a user controllable chopping circuit (20, 30) and rectifying and smoothing the resulting chopped ac signal using a bridge rectifier (BD) and a smoothing capacitor (C2). <IMAGE></p> |
