Integrated monitoring of an electric motor assembly

Abstract:

A method of controlling an electric motor assembly includes receiving sensor feedback that is based at least in part on electrical properties of a variable frequency power signal provided to the electric motor assembly. The method also includes adjusting the phase angle of the variable frequency power signal provided to the electric motor assembly based at least in part on the sensor feedback. The method also includes determining an operational status of the electric motor assembly that receives the variable frequency power signal based at least in part on the sensor feedback.
