Abstract
A slip ring unit which comprises self-lubricated carbonaceous rings and a wear resistive brush made of laminated-elastic-copper-alloy-sheets are used to supply a field current to a field coil which is carried by a rotor of an alternator. Therefore, the space for accommodating the brush and slip ring unit of the alternator is made compact and the alternator size can be made small.
