I noticed the output spec was 33 VAC, so you might need to find a VFD that is not only high frequency but also low voltage. I wonder how they can get a high RPM from such a low voltage. It must be an induction motor? It seems Danfoss drives tend to be high speed. Here is a 240 Volt input, 1000 Hz out unit: http://www.ebay.com/itm/381178968189 If you only have 120 Volts, there are ways to double it, but I would go with 240 if you can. The output voltage can be turned down by setting parameters. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/ ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
