Hello list. There is a synchronous stepping motor for sale on ebay. I'd wager its come from the top of a powerstat stack. However, 72 rpm -at- 60 HZ could be useful for someone wanting to build a computer controlled winding jig like Terry's. http://cgi.ebay-dot-com/aw-cgi/eBayISAPI.dll?ViewItem&item=137681534 Cheers, Gavin Hubbard
