Repulsion Induction motor

[skippyelwell]

I picked up this Leland motor at a garage sale, I've never seen another one like it, kind of unique.
Goes from forward to reverse on the fly by moving a lever.
The data tag says it goes from 500rpm to 2800 rpm but I could only get it produce 2400rpm in a clockwise direction and 2200rpm in the CCW direction, 900 rpm was the slowest I could get without it sounding like it was struggling.
I got it to stop between directions but the magic smoke started leaking so I had to choose a direction quickly.
I have no use for it at the moment but I couldn't pass it up.

Very cool. One of the content creators on YouTube who's name escapes me right now did a video "restoration" on one of those a while back. Until then id never seen or heard of one either.

Not sure what id use one for either at only 1/3 hp, but i wouldn't have passed it up either. Nice/cool find!

Early Delta Unisaws came with repulsion motors.

Great find. If you see one you gotta get it. Pass it on if its not a keeper. These are really cool lost tech. I always thought one of these motors mounted to a die filer or some other small tool from the same era would look so awesome,

I think one mounted on a small precision drill press would be a great application for it.

High start up torque for their HP rating!

This is a lost art as capacitor start or capacitor start/ capacitor run motors are so much cheaper to make than the wound rotors used in the induction repulsion motors.

I had one on a compressor and wired the shift lever to prevent it getting bumped and reverse.

I had a 1/3 HP Repulsion Start Induction Run Leland motor on my 10" Atlas. It worked great.

Never really wanted to do this, but the only downside of it that i could see was that to reverse it you had to pull the brush cover off and slide the brush assembly to shift the starting phase to the other side of the main phase. You couldn't reverse it electrically and it didn't have the lever setup Skeppyelwell showed. You needed a flat head screwdriver.

I might try wiring it up for 220v to see if I can get the rpms that the data tag says it is capable of.
