Abstract
An apparatus for sensing the position of a switched reluctance motor (SRM) is provided, which detects a relative position of a rotor through concentric slit groups formed along different concentric circumferences of a sensor plate and compensates the position of the rotor through a compensating slit which is formed on the sensor plate, thereby effectively preventing the distortion of the position detection pulse from being accumulated and spread by restricting bad influences caused by the distortion of the position detection pulse generated by partial reasons to a relevant position. As a result, since it is possible to prevent the distortion of the position detection pulse from being accumulated and spread by restricting bad influences caused by the distortion of the position detection pulse generated by partial reasons to the relevant position, the rotating torque ripple and noise can be reduced, thereby maximizing the efficiency of the SRM.
