Abstract
There is provided an apparatus and a method for controlling a motor. The apparatus for controlling a motor includes a signal detection unit detecting a first signal, a sampling unit acquiring the number of pulses of the first signal included in a predetermined sampling period, and an operation unit dividing the sampling period into a predetermined number of, a plurality of sub periods, and computing a speed of a motor by allocating predetermined weights to the number of pulses of the first signal included in the plurality of respective sub periods, wherein the operation unit computes the speed of the motor by controlling at least one of the weights and the number of sub periods when the number of pulses of the first signal included in the plurality of respective sub periods is different.
