<p>A slip ring assembly comprises an insulating body having a pair of slip rings on its external surface, each slip ring having electrically connected thereto a respective connector element a part of which is disposed radially inwardly of the slip rings. The body has an internal bore which receives a shaft of a rotary electric machine in use, a side wall of the bore being provided with axially extending recesses which are disposed radially inwardly of the connector element parts respectively. The presence of these recesses, which may alternatively be of helical or annular configuration, ensures that the connector elements do not contact the aforementioned shaft in operation and thereby create a short-circuit. The slip ring assembly is produced by placing the rings and the connector elements in an annular mould cavity whose radially inner surface has projections thereon which correspond to the desired configuration of the recesses in the completed assembly.</p> |
