A motor (20) for driving a movable body includes a cylinder portion (26a) that holds a field magnet, a coil holder disposed rotatably to the cylinder portion, a conducting coil (101a, 101b) wound on the coil holder and generates a rotational force between the same and the cylinder portion (26a) when a current flows in the conducting coil (101a, 101b), a brake coil (111a, 111b) provided on the coil holder, where an electromotive force for generating magnetic field that suppresses relative rotation between the coil holder and the cylinder portion (26a) is induced between both ends of brake coil (111a, 111b) when a current flows in the conducting coil (101a, 101b), and a switch interposed between the both ends of the brake coil (111a, 111b). |
