Harrison Milling Machine

Was your re-winder aware that you intend to drive it from a VFD?

The reason I ask is that apparently 'inverter spec' motors have a higher class of insulation to cope with the fast rising edges of the drive signal. Also don't overlook cooling if it relies on a fan - running at the slower speeds the fans don't shift enough air in certain circumstances.

(Sorry to be a harbinger of doom, I'm sure it'll be fine :) )
