ABSTRACT:
A support carrier of electrically conductive material is secured to the shaft of the machine. A plurality of slip rings are secured to the support carrier, one of the slip rings being fixed thereto directly so that the support carrier will form one terminal of the electrical connection for the slip rings, and an insulating layer is placed over the support carrier over which the other slip ring is located. Preferably, the support carrier is formed with a flange which is notched, one of the notches serving to form an electrical connection for the wire of the field of the machine for connection to the slip ring which is directly secured to the support carrier, the other notch in the flange being wider and gripping around the insulation of the other wire of the field, the wire of the field then being connected to the slip ring which is carried on the insulation. That slip ring, preferably, is also formed with an external flange to which its connecting wire can be secured, for example by soldering. The support carrier may be a solid stub shaft for attachment to the shaft of the alternator, or a tube to be slipped thereover.
