A new method to detect rotor cage fault of induction motor is presented, which monitors if the output power signal comprises a direct component and an alternatingcomponent or only a direct component.
We revised frequency spectrum functions by using weighting factor - the distance between direct component and alternatingcomponent, and improved the acuity of focus measure curve.
