A brush assembly (100) for a slip ring assembly of a rotating electrical machine, having at a brush holder (120) defining a cage into which a brush (103) slides; and a rod (101) extending along a second axis (D2) parallel to the first axis, for supporting the brush holder. One of the rod and the brush holder defines a recess (121), the other has a portion sized to be received into the recess the mating portion (105), the recess defined by a first wall (123, 124) disposed for abutment against the mating portion when, the mating portion received in the recess, the brush holder is driven longitudinally along the rod parallel to the second axis. The recess is defined by a second wall (122) disposed for abutment against mating portion when, the mating portion received in the recess, the brush holder is driven tangentially around the second axis.

A slip ring assembly has an inner ring having an inner ring peripheral wall, an outer wall having an outer ring peripheral wall, and a contact ring having at least one conductive surface positioned between the inner ring and the outer ring. The inner ring has a first inner ring portion and a second inner ring portion that are attachable to each other to create the inner ring. The outer ring has a first outer ring portion and a second outer ring portion that are attachable to each other to create the outer ring. The contact ring has a brush assembly with at least one brush. The contact ring has a first contact ring portion and a second contact ring portion that are attachable to each other to create the contact ring.
