Thats going to be a tough one Todd, its 10x the power of anything I have, and would need to get to 800 hz to run a 4 pole at 24k revs. Are you sure its a 4 pole? All of my 24k's have been 2 pole, doing 24k on 400 hz. 3600 on 60 hz, but needing better cooling to run that slow for long jobs. The one I'm running now, will be spitting steam back into the 5 gallon tank in an hours running at 4k. But is fine for longer jobs at 14k-20k with the mister on. At the higher revs, it never gets the tank above 36C. > Todd Zuercher > P.
