ABSTRACT OF THE DISCLOSURE A flux sensing coil is installed in each phase of the motor stator, and the resulting induced voltages represent the rate of change of air gap flux in that phase. The output voltage signals are integrated, rectified and summed to obtain an average motor flux signal which is in turn applied to vary the voltage to the motor in such a manner as to maintain a substantially constant motor flux level. In this way control errors due to motor parameter changes are eliminated and the flux margin normally required in motor design is reduced to achieve a more efficient utilization of the motor.
