PROBLEM TO BE SOLVED: To provide a thinned motor by reducing the thickness T of the motor, including its motor gear 10, without reducing the number of turns of driving coils or the thickness of coil conductors as compared with conventional motors. SOLUTION: By making the central part of a rotor frame formed into a projected shape, the central part of the motor gear on the rotor frame side is correspondingly formed into a recessed shape, and thereby, the volume in the rotor frame is increased; the number of turns of the driving coils in the space is increased; and thereby the height of the coils is reduced. Since the number of turns of the coils is fixed, the thickness and size of the motor can be reduced, without varying the driving force. COPYRIGHT: (C)2005,JPO&NCIPI
