	Turn it off. Reduce the frequency of the current source. Reduce the amplitude of the current source. Increase the load, a lot. But a VFD and use it. Variable-frequency drive - Wikipedia, the free encyclopedia

	"Have a look on the net for Kramer speed control." Wow, learned something new today! I had no idea something like that even existed. Way too convoluted compared to what is available today, but at one time there must have been a reason for someone to make such a thing, I'm sure. __________________ All I every really wanted to be, was...

	Convoluted it may be, but it works. They're still made so can't be all that bad. I've worked on them up to 2500HP. __________________ The reports of my death are greatly exaggerated.
