Abstract
Official abstract text for this publication.
A method of monitoring health of a mechanical drive train is provided. The method includes obtaining voltage and current signals from at least one phase of an electrical machine coupled with the mechanical drive train. The method also includes representing the electrical machine having a non-sinusoidal flux distribution as a combination of a plurality of harmonic order sinusoidally distributed virtual electrical machines based on the obtained voltage and current signals. The method further includes determining a torque profile associated with one or more combinations of the sinusoidally distributed virtual electrical machines. Finally, the method includes detecting the presence of an anomaly in the mechanical drive train based on the torque profile or spectrum.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of monitoring health of a mechanical drive train, the method comprising: obtaining voltage and current signals from at least one phase of an electrical machine coupled with the mechanical drive train, wherein the electrical machine has a non-sinusoidal distribution of flux in the electrical machine; determining a first torque profile or spectrum of the mechanical drive train from the voltage and current signals that are obtained, the first t…
