Minimum Peak Phase Current Maximum Torque of Dual Winding Motor

Abstract

An analysis of the minimum peak phase current maximum torque of the dual winding motor is presented in this paper. In general, the maximum current determines the size of the motor and the chip size of the switching devices, since the rise in temperature is greater if there is more current. To lower the maximum current, the minimum current required to generate a predetermined torque without increasing the torque ripple using cancellation of the torque ripple generated by the two windings was analyzed. The high harmonic current, which does not generate torque ripple in the dual winding motor, is explained, and the minimum current required to generate a predetermined torque using the high harmonic current is presented. The results of the experiments that were conducted to confirm that the maximum current is lowered without increasing the torque ripple are also presented.
