I have an old Thompson motor from the 50’s It is a 585 frame, what would I replace it with?
Hi Scotty,
The old 585 frame is no longer available, today that motor would be supplied in a NEMA 586/7T frame.
Please note that the motor will be smaller in physical size and consideration would need to be taken to mount the motor in place of the Thompson. Also, this motor would be a lot more efficient!
