Driving circuit for a switched reluctance motor

摘要: This invention provides a driving circuit for switched reluctance motor(SRM) comprising current sensing unit which senses amount flowing into of the SRM and outputs signal representing in circuit, comparing compares reference with response to output from means, stop case exceeds amount, selecting receives Pulse Width Modulated(PWM) rotor position signal, gate controlling turning off switching element during an input means. The protection against excess according present improves reliability SRM, as well eliminates ripple component current(torque ripple) generated at time initial start-up each phase, reduces loud noise motor.
