Abstract
A multiphase electric machine having a failed electrical component detector includes a rotating member and a plurality of electrical components carried by the rotating member and arranged in groups for conducting electrical current. A plurality of detectors is carried by the rotating member with each of the detectors responsive to one of the groups of electrical components for detecting component failures. A plurality of light emitting diodes are carried by the rotating member so as to be grouped into concentric circles according to electrical phase. Each of the light emitting diodes is responsive to one of the detectors such that a component failure, and the phase in which that failure occurs, can be observed by the naked eye. A stationary monitor is disposed about the rotating member and is responsive to the plurality of light emitting diodes for providing an indication of the number of component failures per phase.
