I would also have expected better performance from the coil. The 300 ma
the transformer should be able to keep up with a moderately fast break
With my 6" coil and a 14,400 volt pole pig, the faster I run the rotary
the better performance of the coil. I also use a universal motor and
Max rpm is 10,000. I have throttled it down to run at about 300 bps
have run it as fast as approx. 1200 bps and the coil seems to
But I think the
incredibly high break rates could have been the cause of my first
