Failed electrical component detector for multiphase electric machines
First Claim
1. A multiphase electric machine having a failed electrical component detector, comprising:
- a rotating member;
a plurality of electrical components carried by said rotating member and arranged in groups for conducting electrical current;
a plurality of detector means carried by said rotating member, each of said detector means responsive to one of said groups of electrical components for detecting component failure;
a plurality of light emitting means carried by said rotating member so as to be grouped into concentric circles with each concentric circle of light emitting means having a different radius and being responsive to a different electrical phase, each of said light emitting means response to one of said detector means; and
stationary means disposed about said rotating member and responsive to said plurality of light emitting means for providing an indication of component failures.

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.
