摘要： An apparatus for controlling an electric motor provided to drive a movable object such that a detected actual amount of motion of a movable portion of the electric motor or the movable object coincides with a target amount, comprising: a control-condition changing device operable to change at least one of (a) a resolution of detection of the actual amount of motion and (b) a voltage to be applied to the electric motor, depending upon the target amount; and a feedback motor controller operable to control the electric motor by application of the voltage, on the basis of the actual amount of motion detected with the resolution of detection and the target amount, such that the detected actual amount of motion coincides with the target amount. Also disclosed is a motor control method wherein the resolution of detection of the actual amount of motion and/or the voltage of the motor is/are changed depending upon the target amount of motion.
