That is not normally the throttle mans job, to maintain 240 volts, that is the regulators job, a relatively easy one since its main load as a control was the exciter current being fed to the slip rings of the rotating field. Or it was in this rig at any rate. That one, having a hand throttle, would be an excellent candidate for an arduino running some PID sw, driving a stepper motor to stabilize its speed.
