Suitable Motor?

[juiced]

I came across an OLD washing machine and decided that being bored; i should pull the motor.

    Its a 1/2 HP 115VAC 9.8/8.8 AMP 1725/1140  HZ 60  (about 5-10lbs)

  Lots of resistance when turning by hand.  1/2' shaft.

 It has what looks like a huge CAP bolted on the side, a 'controller box and some spring-mechanism inside on the shaft (almost like a free-wheel).

  So... I know this is a decent little motor, i dont think i could rewire it but do you guys think it would make for a half-decent genny?

           From what i understand, a 50W PV that goes for 400$ outs out about 2.9 AMPS tops, so this must be worth its weight as some kind of genny.

 If not, is there a possibility of some mags inside?

Have you checked the posing "Has anyone tried this ? " I think you will get some answers. It is not the easiest way, but not a bad one.

Actually, i cant find it.

Search and you will find!

Hi Juiced!

i wouldn't waste my time with that one. 1725/1140 rpm means you have 3 windings in there. a 4 pole/6 pole, and a start winding. the free wheel you describe is part of the centrifugal mechanism that engages and disingages the start winding. many of the appliance motors do not even have bolts holding them together (often spot welded together and would need the factory jig to position the parts for alignment for welding) and often the housings are just set into an epoxy. basically these are throw away motors. also most use bushings rather than ball bearings, and the bushings are not designed for axial thrust that you would be receiving from the prop. and lastly, you mentioned that the shaft had lots of resistance when turning the shaft by hand. this means that the bearings have probably run dry of oil and the journals are getting scored. there would be no mags in there to salvage either.

try a surplus centre and see if you can locate a 230/460 volt 3 phase motor. these are excellent to use the windings as is and you would only have to convert the rotor to permanent magnet.

sorry if i stopped your ball from bouncing there, but just wanted to tell you like it is.

have fun

Wow you got it down to a 't'. Epoxied

    Thanks alot.

Well...

If it had bearings...

Why wouldn't it be good to seperate and reconnect the windings (coils)?

Kind of sounds like a motor with a centrifugal mechanism that engages and disingages the start winding is bad.  Why?  Looks easy to go around it.

I have a bunch of 1/4 hp Maytags. Old. Bearings. One speed. Ringer washer (now thats 'old') motor take-offs. Centrifugal mechanism for the starts. About 15 pounds (?). Heavy coil wire.

What is the problem?  I didn't see it.

Too late for these. Some of the armatures are at the machinist.

Ghurd!

some of the old ringer washer motors would be a good choice. hopefully they have ball bearings too. i was actually refering to the newer style of "junk" motors that are welded or epoxied together. these are the ones i would consider no good for conversion. on the other hand, yes they could be, but your efforts would be better rewarded using a quality motor to start with.
