Abstract
A motor controller for an electric motor is provided. The motor controller includes an inverter configured to supply current to stator windings of the electric motor. The motor controller further includes a plurality of sensors configured to generate a sensor signal in response to detecting a parameter. The sensor signal represents a measured parameter. The motor controller further includes a processor coupled in communication with the inverter and with the plurality of sensors. The processor is configured to, in a first mode, transmit a control signal to the inverter to operate the electric motor at a first frequency. The processor is further configured to receive the sensor signal from the plurality of sensors. The processor is further configured to determine a first fault condition is present at the electric motor based on the measured parameter represented by the sensor signal.
