11. A method for controlling a motor driving apparatus driving a motor including a plurality of windings corresponding to each of phases through a mode change switch and a plurality of inverters, the method comprising:
determining, by a controller, a reverse magnetic flux, a first output power limit in a closed end winding mode in which the motor is driven by turning on the mode change switch to connect one ends of the plurality of windings and activating one inverter among the plurality of inverters, and a second output power limit in an open end winding mode in which the motor is driven by turning off the mode change switch and activating the plurality of inverters connected to both ends of the plurality of windings;
performing, by the controller, a first mode determination based on the determined reverse magnetic flux and a second mode determination based on the first output power limit and the second output power limit;
determining, by the controller, a driving mode of the motor as the closed end winding mode or the open end winding mode according to a first result of the first mode determination and a second result of the second mode determination; and
controlling, by the controller, the mode change switch and the plurality of inverters according to the determined driving mode.
