I’ve spent about 2 hours Googling and all I’m getting is a headache plus more and more confused :-(
I’m trying to build a 12” shop made disc sander, and the first motor I tried was WAY underpowered. I dug around in my shop and came up with 2 more electric motors, both of which are plenty powerful, but both of them run at 3450rpm, which is too fast for a sander. Both of these motors have capacitors on them (if that info is helpful)
Since I’m no electricial geenious, I’m looking for some help here. I’ll post good clear photos of both the info-plates and I’m hoping SOMEONE way smarter them me can decifer if I can use a HF router speed control to drop the speed by about 1/2… Thanks in advance.
This Doerr motor was from an old air compressor. It has a mounting plate on the base already and the capacitors are mounted on the outer shell of the motor.
And this Marathon Electric motor came out of a commercial floor sander. It’s a beast, and I know it would have enough power. I also already know it is set for 110v. There’s no mounting plate on this one but I already have a way to mount it if it’ll work.
