Systems and methods for component monitoring in an electric motor

A method for controlling a drive system, said method comprising:

• in a first mode, transmitting, by a processor, a control signal to an inverter coupled in communication with the processor, the inverter configured to supply current to stator windings of an electric motor, the control signal causing the inverter to operate the electric motor at a first frequency;
• receiving, by the processor, a sensor signal from a plurality of sensors coupled in communication with the processor, the plurality of sensors configured to generate a sensor signal in response to detecting a parameter, the sensor signal representing a measured parameter;
• and
• determining, by the processor, a first fault condition is present based on the measured parameter represented by the sensor signal, wherein the first fault condition indicates a fault within the drive system.

A drive system comprising:

• an electric motor comprising stator windings;
• and
• a motor controller comprising:
• an inverter configured to supply current to said stator windings;
• a plurality of sensors configured to generate a sensor signal in response to detecting a parameter, the sensor signal representing a measured parameter;
• a processor coupled in communication with said inverter and with said plurality of sensors, said processor configured to:
• in a first mode, transmit a control signal to said inverter to operate the electric motor at a first frequency;
• receive the sensor signal from said plurality of sensors;
• and
• determine a first fault condition is present based on the measured parameter represented by the sensor signal, wherein the first fault condition indicates a fault within said drive system.
