A motor control apparatus includes a position controller that generates a velocity command on the basis of a position difference between a position command and a position feedback signal, a switcher that switches the position feedback signal to be input to the position controller from a first position signal detected by a laser interferometer to a second position signal detected by a position sensor, and a phase compensator that compensates for a phase delay of the second position signal switched by the switcher relative to the first position signal.
