Degauss time detection in electric motors
Example systems and processes compare sampled values of a floating phase voltage and/or outgoing phase current of an electric motor with a corresponding reference to identify a degauss time period. Post degauss time period identification, sampled values are compared with a threshold to identify a settling time period following the degauss time period.
