AXIAL SLIDING COMMUTATOR HAVING NOBLE-METAL PLATED COMMUTATOR FRAGMENT, ROTOR EQUIPPED WITH THE COMMUTATOR AND AXIAL-SPACE TYPE MOTOR EQUIPPED WITH THE ROTOR

摘要

PROBLEM TO BE SOLVED: To provide an axial sliding commutator that does not cause an increase in current consumption by eliminating loss induced by magnetism, a rotor equipped with the commutator, and an axial-space type motor equipped with the rotor.;SOLUTION: The axial sliding commutator (1) comprises a noble-metal plated commutator fragment (1s) of which the surface is subjected to noble-metal plating (A) via an isolation phase for isolating copper, and a noble metal between a plurality of copper-group metal plate segments. The isolation phase is formed by non-magnetic electroless nickel plating (N).;COPYRIGHT: (C)2004,JPO
