Abstract

PURPOSE: To reduce the number of contact points, raise the reliability and increase the torque and the efficiency, by fixing commutator pieces to a stator and bringing at least one commutator piece into contact with a plurality of commutator contact pieces and rotating the commutator contact pieces together with a rotor to serve also as a governor.
CONSTITUTION: The commutator 10 is attached to an insulator rest 12 fixed on the stator. Leaf springs 4, the tips of which are fitted with the commutator contact pieces 13 and weights 3, are fixed on the rotor by rotational frequency adjusting screws 14. When the rotor exceeds a prescribed rotational frequency, the contact pieces 13 are separated from the commutator 10 so that the real rotational frequency is decreased. The prescribed rotational frequency is adjusted by turning the screws 14. Because the contact pieces 13 serve also as a governor, the number of contact points is reduced and the reliability is raised. Since the contact pieces 13 are always in contact with the commutator 10, the torque and the efficiency are heightened.
