The Statically Regulated Controlled Rectifier Generator gives improved performance and longer service life by applying a method of excitation controlled by an automatic voltage regulation system that contains no moving parts. The generator voltage build-up system uses only one moving part: a relay, which operates only when the generator is started or shut down.Generation Of Voltage
The generator is constructed with the armature coils wound on stator (L4) and the field coils wound on the rotor, designated in the wiring diagram as revolving field (L3). The field coils are wound on magnetic steel that will retain a small amount of residual magnetism. The revolving field is connected directly to the engine flywheel through the generator shaft and coupling.As the engine turns revolving field (L3), a small amount of alternating current voltage is generated in stator (L4) by the influence of residual magnetism in the revolving field. A portion of this alternating current (AC) is rectified to direct current (DC) and is directed back to the revolving field to increase its magnetism. The procedure of excitation can be traced on the SRCR Generator Wiring Diagram by following the path of AC power from stator (L4). This AC power from phase 1 and phase 2 passes through noise suppressor (FL1) through fuses (F1 and F2), wires (35 and 36) to the power rectifiers (CR3) and (CR4) mounted on heat sink (E1) which rectifies the AC power to provide half wave DC power. Voltage surge suppression diodes (CR7 and CR10) across power rectifiers (CR3 and CR4) limit abnormal transient peak voltages on the power rectifiers. Fuses (F1 and F2) are the "fast blow" type and provide protection against secondary damage of the excitation circuit if any one component should fail or malfunction.The half wave DC power from the rectifiers continues from heat sink (E3) through regulator gain resistor (R1), wire (30), and noise suppressor (FL1) to the positive "+" end of revolving field (L3). To sustain current in revolving field (L3) when (CR1) IS NOT conducting (because of no circuit from stator phase 3) there is a circuit from the negative "-" end of the revolving field to the positive "+" end of the field. The circuit is from terminal (26) through noise suppressor (FL1) to terminal (27) through wire (27), field rectifier (CR5), regulator gain resistor (R1), through wire (30) to terminal (28) and through the noise suppressor to the positive end of the
