Abstract
Provided is a motor driving apparatus used for driving a motor including a first winding group and a second winding group to which three-phase alternating-current voltages are applied. The motor driving apparatus includes a first inverter and a second inverter; the first inverter applies an alternating-current voltage to the first winding group; and the second inverter applies an alternating-current voltage to the second winding group. A first induced voltage detector, a second induced voltage detector, and a third induced voltage detector are provided as voltage detectors for detecting induced voltages induced either in the first winding group or in the second winding group.
