Assignee:

General Electric Company - Schenectady NY

International Classification:

H01R 39/38
H02K 13/00
H02K 5/14

Abstract:

A brush holder apparatus includes a stationary support member having at least one groove, a fork electrical connector, and a conductive bar configured to pass through a portion of a main body of the stationary support member. The conductive bar provides electrical conductivity with a collector mount and fork electrical connector. A brush holder is releasably affixed to the stationary support member, and has at least one rail that slides along the groove(s). The brush holder has a knife electrical connector that mates with the fork electrical connector. A brush spring is clipped on the brush holder, and presses a brush against a collector of a dynamoelectric machine. The brush spring is replaceable in the brush holder. The brush spring or brush holder has a friction enhancing material attached to an area where the brush spring attaches to the brush holder.

International Classification:

H02K 13/10

Abstract:

A brush holder apparatus has a stationary support member having two opposing grooves, a fork electrical connector, and a conductive bar passing through a main body of the stationary support member. A brush holder is releasably affixed to the stationary support member, and has two rails that slide along the grooves. The brush holder's knife electrical connector mates with the fork electrical connector. A brush spring is clipped on the brush holder, and presses a brush against a collector. A brush lead connects the brush to a brush terminal. The brush terminal has a generally L-shaped body with a lower part thereof retained under a terminal compression plate, and an upper part thereof located on a front side of the terminal compression plate. The brush terminal is removed from or installed into a front side of the brush holder, and by hand or without the use of any tools.
