Title:
CURRENT COLLECTOR FOR ROTATING ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JPH1094221
Kind Code:
A
Abstract:

To provide a current collector which can prevent generating of a serious failure such as phase-to-phase short circuit and a ground fault due to brush wear powder and make contribution to the cleaness installation environment.

This current collector is provided with a collector ring 3 mounted on a main shaft 1, a brush 7 which slides on the collector ring 3, and a fan for cooling the sliding part. A rotating screen 9 is installed on the outlet side of a ventilation route by means of the fan 8, and brush wear powder generated by mechanical sliding between the collector ring 3 and the brush 7 is attracted by the rotating screen 9. It is thus possible to prevent a serious failure such as phase-to-phase short circuit and a ground fault in the collector ring 3 due to deposit of brush wear powder, make contribution to the cleaness installation environment, create a good working environment, and facilitate maintenance and control.
