Abstract
A method for controlling driving of a Switched Reluctance Motor (SRM) is capable of operating the SRM normally according to a phase under the normal state in case a noise is inputted to a position sensor in the SRM. In order to achieve the advantage, the method for controlling driving of a three phase SRM using a position sensor having a rate of a rotor and a stator is 6/4 or 12/8 includes the steps of generating a sensor signal according to the position of a rotor in the SRM and operating the SRM by turning on respective phases in the SRM at the point of detecting a rising edge of the sensor signal and turning off the phase at the point of detecting a falling edge of the next sensor signal.
