A motor driving system includes motor driving circuitry configured to operate an electric motor. The system further includes a controller that is configured to send a signal to energize the electric motor and to measure a back electromotive force voltage of the electric motor. The controller is further configured to determine a temperature value based on the measured back electromotive force voltage using a back electromotive force voltage mapping that maps back electromotive force voltages to temperature values. The controller is further configured to determine an expected winding resistance value based on the determined temperature value using a resistance mapping that maps winding resistance values to temperature values. The controller is further configured to measure a winding resistance of the electric motor, to compare the measured winding resistance of the electric motor to the expected winding resistance value, and to output a match result indication based on the comparison.
