Abstract
A signal processor is configured to receive signaling containing information about a sensed sinusoidal waveform of magnetic flux caused by a current flowing in a winding of a motor having a component of distortion caused at least in part by a magnetic flux created by the current flowing, and also about a pure sinusoidal waveform of a sensed fundamental frequency of the magnetic flux; and determine corresponding signaling containing information about anomalies in the motor that depends on a relationship between the sensed sinusoidal waveform and the pure sinusoid waveform, based upon the signaling received. The signaling may be sensed and provided by a motor magnetic flux sensor attached externally to the motor frame.
