Alternators - LUCAS 1967-1972: Description
Construction of the Lucas "AC" type alternators is similar to the "ACR" type, except that a voltage regulator of micro-circuit construction is incorporated as an integral part of the "ACR" alternator. "AC" type alternators use an external regulator.
Both type alternators have stators consisting of three-phase, star-connected windings on a ring end cover and drive end bracket. The rotor is of eight or 12-pole construction (depending on model) and carries a field winding connected to two face-type slip rings. It is supported by a ball bearing in the drive end bracket and a needle roller bearing in the slip ring end cover. Two carbon brushes, one positive and one negative, bear against a pair of concentric brass slip rings. Slip ring end cover also carries six silicon diodes, connected in a three-phase bridge circuit to provide rectification of the generated alternating current output. On some models, field windings are isolated by means of a relay incorporated in the ignition switch circuit.
