ROTOR POWER FEEDING DEVICE OF ROTARY ELECTRIC MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a rotor power feeding device of rotary electric machine that can avoid useless power loss and heat generation by rejecting creeping discharge between brushes and can control reduction of operation life of member. SOLUTION: The internal surface of diameter of a reinforcing member 71 provided in the gap in the axial direction between brush holders 6 is covered with an electrically insulating separator 91, and the separator 91 has a projected portion 911. Thereby, creeping discharge between brushes can be rejected to eliminate useless power loss and heat generation and moreover the rotor power feeding device having eliminated reduction in operation life of the member can be realized.
