PURPOSE:To miniaturize the whole driving device as well as to increase the generating torque with the increased inertia of a rotor for the subject motor by a method wherein a battery is built-in inside the rotor and the rotor performs an additional function as a battery storing case. CONSTITUTION:A battery is built-in symmetirically around the rotating shaft 3 inside the rotor 2 and on the outer circumferential surface of the rotor 2, a permanent magnet 5 (5-1-5-4) having necessary number poles are installed. In addition, a commutator bar 6 (6-1-6-4) is installed on the rotating shaft 3 and the necessary wire connection with the built-in battery is performed. Also, stator magnetic poles 1-1-1-3 having a winding (a) are installed on the inner circumferential surface of the casing 1, the stator winding (a) is connected to a brush 7 (7-1-7-3) through the intermediary of a tripple-pole switch 9, and at the same time, this brush 7 is slidably contacted to the commutator bar on the rotating shaft. |
