As many know I was blessed at a recent auction. I got a 3hp 3 phase PM 66 for 50.00. I plan to fully restore the saw by sanding everything down to bare metal and applying fresh paint finish. I plan to disassemble the saw entirely to thoroughly clean and lube.

I plan to swap out the motor instead of going the VFD route. I am thinking it is very likely the PM motor runs fine but the saw is a 1982 so the motor has probably seen some better days. I ran a search on eBay for Powermatic 66 and found a single phase 3 up motor for reasonable cost. But I am not sure it will bolt up or if will need the exact specific motor. On Monday I will try to call Powermatic but I am thinking if anyone has experience let me know.

I also need to replace my height adjustment wheel which I know grizzly sells those but just not sure if they will fit or not.

Thanks for all advice.

The motor I found on ebay is found at the following link:

The listed price is 338.00 plus about 42.00 shipping. I would hate to purchase a motor and find it does not fit. Thanks everyone.

If memory serves…. all you need to do is match the frame. If your PM66 uses a 145TC frame motor, then the one you’re looking at on eBay would fit. The eBay motor is a 145TC frame with a C face. I’d call Powermatic just to be sure, definitely, but sounds like you’re on the right track.

The saw is at the shop, but some online research shows the PM66 to use a 145TC frame.

I am also going to check at our local Tractor Supply store, they carry electric motors there that I believe are Baldor. Not sure if they will have exactly what I need though but might check into it.

I do think the motor on Ebay will work, will look more into it on Monday. Thanks.
