Two Ideas... 1.) Use gears as a transmission. A multi-speed bicycle can be used for this. 2.) Use a friction brake on the rotating device while keeping the voltage and current to the AC motor constant. Changing the friction work load on the regulated AC motor will vary the speed. (...

Put a inductive load in the discharge circuit. A suitable inductive resistance will prevent the switch contact arcing, as it opposes the discharge current surge. To prevent oscillation, remember to also include a dampening diode parallel to the inductor. And, just my personal preference...
