Abstract
PURPOSE:To prevent the generation of sparks on the switching device of the subject motor by a method wherein the direction of current, to be feeded to an armature coil by the cam provided at a rotating shaft, is switched. CONSTITUTION:When the first protrusion of the cam provided at the rotating shaft and the point 30a of a spring 30 are sliding, a point of contact 38 is closed and a current in the direction of continuity of a diode 48 is fed to the armature coil 10 from an AC power source 44. Then, a rotor 18 is rotated, the sliding movement of the first protrusion 100 and the point 30a of the spring 30 is stopped and when the second protrusion 102 and the point 28a start a sliding movement, a point of contact 40 is closed and a current in the direction of continuity of a diode 52 is fed to the armature coil 10 from the AC power source 44. Through these procedures, no sparks are generated as a driving current is not applied to the rotating section, and the damage at the sliding section can also be reduced.
