Abstract: A method for monitoring an inverter module for a multi-phase electric motor/generator includes deactivating operation of the inverter module, monitoring voltage on a high-voltage bus configured to supply electric power to the inverter module, detecting occurrence of a true fault when a change in the voltage on the high-voltage bus is greater than a predetermined threshold, and detecting occurrence of a false fault when the change in the voltage on the high-voltage bus is less than the predetermined threshold.

Abstract: A method for monitoring an electric motor employing a pulse-type rotational position sensor includes monitoring a signal output from the pulse-type rotational position sensor and a reference signal associated with a control signal for the electric motor. A position of a rotor of the electric motor coincident with the reference signal is determined based upon a nominal rotor position, a nominal rotational speed of the rotor and a time between the reference signal and a falling edge of the signal output from the pulse-type rotational position sensor. The electric motor is controlled based upon the position of the rotor.
