| 1. A method for controlling an electric motor, said method comprising the steps of:
determining multi-phase voltage command values;
determining a star voltage of the electric motor;
determining multi-phase voltage output command values as a function of said star voltage and said multi-phase voltage command
values; and
supplying multi-phase voltage to said electric motor in accordance with said multi-phase voltage output command values to
energize the electric motor.
