Disclosed herein is a motor control apparatus and a method thereof. The operation efficiency of a compressor may be maintained by using a sensorless algorithm, sampling a current applied to a motor more than twice within a period of the triangular carrier wave for performing pulse width modulation to calculate a reference voltage, driving the motor according to the calculated reference voltage to improve control resolution, and performing a high-speed operation while reducing a volume of the compressor, without adding a separate hardware when controlling the operation of the motor provided in the compressor at a high speed. |
