True indeed. But few Hardinges (for example) were made or intended for
use with inverters so such info can be very very hard to find.


And
until the last decade or less..inverter duty motors were exceptionally
rare.


And from what I have been able to find a quite a bit more expensive.




Well...I just quoted a guy on a GE motor for his Hardinge HC
Chucker...new from Hardinge...$3804.27

I think he is going to go with a VFD....G

One could not be a successful Leftwinger without realizing that,
in contrast to the popular conception supported by newspapers
and mothers of Leftwingers, a goodly number of Leftwingers are
not only narrow-minded and dull, but also just stupid.
