Yes, It's me again ; )
I have a question about DC TCs...
If you have a power supply that has a high current, say 300 mA, with a
reasonable voltage, 12kVdc, and a MMC with a capacity of .03uF, couldn't you
run your coil in synchronism using a non salient pole motor? A break rate of
120-150 bps would yeild synchronism right?
I liked Greg Hunter's MOT supply, but I also noticed that he blew his MMC. He
was using seacors with a dv/dt of 4000. I think, since he was using an air
blast gap, his brak rate went as high as the transformer would let it, thus
over-discharging the caps. He said they "blew up" on his webpage, so I'm
guessing that heat built up in his caps (which have a plasic casing might i
add) then they simply exploded.
I'll be using a similar setup with a MMC with a dv/dt of 2700... However, If I
keep the bps limited with a good rotary gap, then my MMC should keep nice and
cool. Right? Also, a good safety gap would be necessary to keep the MMC within
it's voltage rating.
Does anyone on the list have a pair of identical MOTs complete with capacitors
and diodes they would be willing to part with? If not does anyone know of a
source for them? Here in LaCrosse, WI where I live, the city is kinda anal
retentive about their junk. We don't have a scrap yard within 60 miles of my
house : ( When people throw away stuff like microwaves, they have to pay big
buck to get rid of them, but the city doesn't let me take any "off their
