Hey that's pretty cool! I see how the motor is wired with the capacitor but how does that make it synchronous?

Hi , I solderd two diodes to the commutator it now acts similar to the cutting flats in the armature mod , the capacitor is for a voltage dropper instead of using a variac , tha cap brings the voltage down to about 80volts as 240volts cooks it in a few seconds . The orange light is flashing at 50htz mains frequency .its just a standard 240v led bulb with the smoothing capacitor removed .

It's synchronous because it spins at a constant RPM dictated by the AC line frequency. It's intended to be used to switch high voltage from a capacitor which is also supplied by the AC line which is in phase with the spark gap motor AC line. Ideally, the spark gap will close/switch/conduct at some even harmonic of the line frequency, at/near peak voltage (unless the phase is shifted) i.e. 60Hz/2, 60Hz x 2 or 4x or x8... It allows maximum power transfer and regular discharges compared to an asynchronous spark gap, which fires whenever the electrodes happen to be close enough for whatever voltage the capacitor is at any given moment. Maximum voltage could be achieved by setting a ratio and a phase that allows a discharge and begin recharge every 180 degrees at peak + and - voltages, which would be 2 per cycle or 120Hz with 60Hz line. Alternately it could switch at every node and antinode (at 0V, max+ and max -). I think matching the line frequency would be difficult unless you wasted/shorted every other spark or half wave rectified the HV to capacitor (I could be wrong)

@@1000000volts Oh ok neat! Thanks for the explanation. Very simple electrically but achieves a useful phenomenon.
