I have on the back burner a magnetically assisted super-series rotary
consisting of ring ceramic magnets, not much different in strength and
dimensions to one's used on Microwave Oven Magnetrons. The ring magnets
are available from a local supplier. I designed a 'C' frame out of
1018 mild steel (two notches and a 90 deg. brake) and a magnetic
focusing keeper bolt like wise out of 1018 mild steel.
Magnetic assist on a rotary gap, especially to stationary (HV)
electrodes that see 100% duty cycle may significantly improve
rotary performance.
