PROBLEM TO BE SOLVED: To easily suppress rotation unevenness of a rotor which supports a body to be supported. SOLUTION: The rotor control apparatus is equipped with: the rotor which rotates while supporting the body to be supported at the circumferential surface; a motor which rotates the rotor when a current according to a current profile indicative of a current size is supplied; a detecting member which detects a rotation state of the rotor during rotation; and a control part which displays the size of a correction current corrected on the basis of the rotation state detected by the detecting member, generates a one-rotation current profile of an amount of one rotation of the rotor, and supplies the correction current responsive to the generated one-rotation current profile to the motor, thereby rotating the rotor.
