Scooped this from Sear & Roebuck service department dumpster; the fuse was popped on control board also w/ damage from rough handling. The three wired PCB at center is nice optical tach, will be ringing it out to see if I can salvage it.
120V 2.5amp 3-phase 12 coil variable speed motor, each coil set 2.15ohm. Rotor width/height is square at just over 3 inches. With swept area so small this won't make any real power, and will cog like a mule if I can get decent neos in it. Motor is rated for intermittant use, 10 on 20 off & 50C.
Eight 1/2" x 1/2" x 2" bar magnets would fill the teeth of the rotor but I think a non ferrous rotor would kick out alot if one could skew bar mags, but this is only 3 inches across so it's kind of a lost cause.
The rotor has a small amount of residual magnetism, I spun it up to 2000rpms and read 3 volts AC off one phase. The bearing nearest the rotor core is spring loaded.
Any opinions? I'm thinking tear it down to get the coils out of it, maybe save the end pieces, bearings/shaft for another project....
