Apparatus and method for controlling motor
An apparatus for controlling a motor may include: an inverter unit configured to output 3-phase AC currents through a plurality of switches to be switched by an input control signal to drive a 3-phase motor; a current detection unit including a plurality of current sensors configured to detect two or more phase currents among the 3-phase AC currents flowing through the 3-phase motor; and a control unit configured to receive respective fed-back phase currents detected by the plurality of respective current sensors, correct the phase currents by applying, to the fed-back phase currents, respective correction gains estimated in advance on the plurality of respective current sensors so as to compensate for a current detection deviation of each of the plurality of respective current sensors, and then control the inverter unit based on the corrected phase currents to control driving of the 3-phase motor.
