| description | A drive control apparatus for multiple-winding motor includes: a modulation rate phase command generation unit which calculates currents of first and second inverters for driving a multiple-winding three-phase motor and generates a modulation rate command and a phase command for equalizing the currents; a pulse number determination unit which determines the number of pulses per half cycle on the basis of a frequency command; a pattern table for storing switching patterns; and gate signal generators which control the first and second inverters, using an optimal switching pattern based on the number of pulses, wherein the modulation rate phase command generation unit performs control for equalizing currents of the first and second inverters, and the phase or frequency at which the control is performed is changed in accordance with any of the number of pulses, the modulation rate, the frequency command, and the switching pattern. |
