A control circuit and method for controlling an electric machine has a plurality of stator windings energized by current signals. The control circuit includes a driver circuit that generates three pulse width modulated current signals responsive to an error signal that is representative of a phase angle error, where each of the respective current signals is one phase of a three phase signal. The driver circuit also generates phase information associated with the current signals. The machine has three input terminals each of which receives a respective one of the three current signals generated by the driver circuit. A multiply circuit multiplies the terminal voltage of at least one of the three terminals with the phase information to generate the error signal.
