For the practical using the SRM by domestic application, we must of all have solution to the noise and the vibration. This paper presents the acoustic noise emitted from the SRM. The emitted noise it particularly strong when the frequency of deformation coincides with that of a natural mechanical resonance of the stator. To reduce the emit acoustical noise varying the switching frequency randomly. We will consist of SRM control system by using DSP, and confirm the effects of the noise reduction.<br/> <br/>

This paper presents a driving method of 3-phase 4-poles SRM(switched reluctance motor) drived by switching angle control. In this study, the switching angle is determined from approximated analysis and computer simulation by using MA TLAB@ for high efficiency according to the speed and torque required by load, and then microcontroller controls the switching angle of asymmetrical inverter in SRM driver Also, we experiment the maximum torque driving and maximum power driving by controlling switching angle available to electric vehicle
