1. A motor-driving apparatus for driving a motor having a plurality of windings corresponding to a plurality of phases, respectively, comprising:
a first inverter including a plurality of first switching devices and connected to first ends of the plurality of windings;
a second inverter including a plurality of second switching devices and connected to second ends of the plurality of windings;
a plurality of third switching devices having one-side ends connected to a second end of each of the plurality of windings and the other-side ends connected to each other; and
a controller configured to adjust an on/off state of the first to third switching devices based on required torque of the motor and a reverse magnetic flux value corresponding to the required torque.
