A method for measuring speed of an MDPS drive motor may include: receiving, by a controller, A and B pulses having a phase difference of 90 degrees from an encoder during a first reference time, and measuring information of the pulses; receiving A and B pulses having a phase difference of 90 degrees from the encoder again during the first reference time, and remeasuring information of the pulses; selecting any one of the measured pulse information and the remeasured pulse information as data for calculating the speed of the motor, based on the measured pulse information and the remeasured pulse information; and calculating the speed of the motor, based on the selected data.
