Abstract:
Methods and systems are provided for aligning a resolver in an electric motor system. The method includes commanding a d-axis current command and a speed command, operating an electric motor without a load in response to the d-axis current command and the speed command, determining a rotor speed in response to the speed command, and determining an offset of the resolver based on the speed command and the rotor speed when the rotor speed has substantially stabilized.
