ROTOR FIELD FEEDBACK AND AUXILIARY POWER

The AC voltage developed in the field winding is fed to the full wave field bridge. The DC output of the bridge is filtered by the field capacitor and controlled by the printed circuit board according to the output control setting. This filtered and controlled voltage is fed to the rotor winding via the brush and slip ring configura- tion. As the feedback voltage is increased or de- creased, the outputs of the weld and auxiliary windings are increased or decreased.

When full field voltage is applied to the rotor and the engine is running at high speed (3700 RPM), a 230 AC voltage is developed in the stator auxiliary winding. This winding is tapped to provide 115 VAC. The two voltages, (115 VAC and 230 VAC), are connected to the appropriate receptacles and offer 9000 watts (total) of continuous AC power.
