This is the feed motor used on Royal saws and maybe more; good buy.

I'm guessing most manufacturers sourced feed motors from Grainger. If there is a Grainger number (like your number-letter-numbers) easy to match up. If not if you knew rotation and rpm's you can either find in catalog by spec's or their phone support people are really good. Heard of a guy that got a deal on an LS12 because feed did not work. Had a new feed motor but he found it ran backwards.

When folks repair these motors (repack the gearbox), often times without paying attention they will go back together and run in reverse mode. Fairly easy to reverse directions on these shaded pole motors. (not all gearboxes might be designed to run in reverse though)

I opened my saws up and the motor Grainger has is the exact model number originally (and currently in my saws) used. Dayton 4rpm 3M098. I ordered 4 of them for right at $80 shipped with tax. Motors appeared frozen and for the price, can't go wrong. Plug and play...with a little rewiring

After opening up my Raytech 6" and 10", see that they were original equipment on those too. Thanks for the heads up.
