Abstract
A rotor for an electrical machine according to one embodiment of the present invention includes first and second individual slip rings mounted on a rotor shaft. A first end of the coil wire for the rotor passes through a first axial passage in the first slip ring and is terminated to conductive material on an axial end of that slip ring. The other end of the coil wire passes through a second axial passage in the first slip ring and through an axial passage in the second slip ring and is terminated to conductive material on an axial end of the second slip ring. The second axial passage of the first slip ring is electrically insulated from the conductive material of that slip ring, so the second wire end does not inadvertently short-circuit to the first conductive material. Also, the first and second slip rings are each designed to cooperate in providing a gap therebetween which provides space to accommodate the termination of the first wire end onto the axial end of the first slip ring.
