PROBLEM TO BE SOLVED: To obtain a motor which stabilizes the rotation state of a rotating body by a simple constitution. SOLUTION: A rotating-body receiver part 12i which receives the rotating body directly is arranged in a part corresponding to the magnetic-pole boundary part between the N-pole and the S-pole of a rotor magnet 12g in which both the absolute value and the change value of an electromagnetic force in a thrust direction are minimum. As a result, the propagation of a vibration to the rotating body from a rotor assembly 12 is made minimum.
