Abstract
PURPOSE: To absorb a generation of surge, by providing a main commutator, insulated by a slit, further providing an auxiliary commutator segment, insulated by a slit, with a connection made by a resistance wire between each main commutator and auxiliary commutator segment, and providing a brush for sliding on the main commutator and the auxiliary commutator.
CONSTITUTION: A main commutator 1 forms a plurality of commutator segments a1 to a3 by a slit 3, with each main commutator segment providing auxiliary commutator segments all to a13 divided by slits 5 to 8. On a protrusion a of the main commutator segment is wound a rotor winding L in n turns. Between the main commutator a1 and the auxiliary commutator all, is made a connection by a winding n1 for reproducing a resistance value R1, between the auxiliary commutator all and a12, made a connection by a winding n2 having a resistance value R2, and between the auxiliary commutator a12 and a13, made a connection by a resistance wire n3 having a resistance value R3. At a point end of brush 4, are formed brush pieces b1, b2, with the brush piece b1 mainly sliding on the main commutator and the brush piece b2 sliding on the auxiliary commutator.
