General Mach Discussion / Re: Inverter Duty Motor

The Inverter duty motors have a higher class of insulation, or should I say they are guaranteed to have such a clas of insulation. Some of the older motors may well have had similar quality insulation but no guarantees
One other thing is Inverter duty motors often have better cooling so that they dont overheat from long periods of low speed.
If your motor is reasonable quality I would think you will have no problems running it from a VFD, my Bridgeport motor will be about 26yrs old so it wouldnt have been Inverter Duty and its fine, also the even older motor that was on my manual Bridgeport (1974) ran great on a VFD.
