ABSTRACT:
A motor for driving a movable body includes a cylinder portion that holds a field magnet, a coil holder disposed rotatably to the cylinder portion, a conducting coil wound on the coil holder and generates a rotational force between the same and the cylinder portion when a current flows in the conducting coil, a brake coil 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 is induced between both ends of brake coil when a current flows in the conducting coil, and a switch interposed between the both ends of the brake coil.
