| Systems and methods of detecting a failure of a permanent magnet synchronous motor system. A current of each phase coil of the motor is monitored. A value indicative of the power of the motor is compared to a threshold value indicative of power during a low power detection period. If the value indicative of the power fails to exceed the threshold value indicative of power for the entire low-power detection period, the system indicates a first error condition. The method also monitors the speed of the motor and indicates a second error condition if the speed of the motor remains below a speed threshold for an entire speed failure detection period. A third error condition is indicated if the current of at least one phase of the motor remains below a phase current threshold for an entire loss of phase detection period. | ||||||

| An electric power assembly for a vehicle is disclosed. An electric motor includes a stator and a rotor being rotatable about a pivot axis relative to the stator. An inverter is coupled to the electric motor and includes a power switching device that outputs an electrical signal from the inverter at a first frequency and having interference at a second frequency.

The stator is electrically connected to the inverter to receive the first frequency such that the stator produces a first magnetic field. A frequency filter is attached to the rotor and directs the portion of the electrical signal having the second frequency to the rotor such that the rotor produces a second magnetic field that interacts with the first magnetic field to rotate the rotor about the pivot axis relative to the stator. | ||||||
