Abstract
A method and an apparatus for reducing noise of a switched reluctance motor, includes: supplying a PWM signal as a driving signal to a driving circuit of a switched reluctance motor; and varying a carrier frequency of the PWM signal as an operation period of the switched reluctance motor varies; if the switched reluctance motor changes phase, determining that the operation period of the switched reluctance motor varies.
