ABSTRACT:
A reduced vibration and reduced noise controller for a switched reluctance machine system. A decoder circuit monitors firing signals which are used to energize a phase winding in the switched reluctance machine over an angular period of rotor rotation. When the firing signals indicate that a predefined switching event has occurred, one or more timed voltage pulses are applied to the phase winding at fixed points in time following the predefined switching event. The timed voltage pulses induce vibration forces in the motor which actively cancel unwanted vibrations in the motor system, thus reducing unwanted vibrations and acoustic noise.
