The Statically Regulated Controlled Rectifier (SRCR) generator uses a method of excitation controlled by an automatic voltage regulation system that has no parts that move. The voltage build-up system has one relay.The generator is made with the armature coils wound on stator (L4) and the field coils are wound on revolving field (L3). The field coils are wound on magnetic steel that will retain a small amount of magnetism even when there is no current to the field. The generator shaft is connected to the engine flywheel by a flexible coupling. The difference between earlier and later SRCR voltage build-up systems is in the wiring of build-up relay (K1).Voltage Build-Up (Earlier)
Build-up relay (K1) has the only part that moves [except for revolving field (L3)] in
