Gloat Electric Motor

Just take it apart and see, it should be easy and is likeyl fixable.

Are you implying that an induction motor can be used as a generator?

You'd be way better off to saw out the copper...

Well , yeah. That won't work? No magnets?

No magnets. If I recall, you can use an induction generator to *add* power, but you need another generator running to provide the excitation.

An induction motor can be used as a generator. Now it isn't designed for that, so it has some limitations.

Search on Google for " induction motor generator " and you will find lots of information, more than I want to type.

It's TOAST. Bummer

My puller could be modified to get the bearings off, hopefully they are the same size cause I'm off to see if someone has a bigger puller. Suppose ya have to press the stator off to get the shaft for other uses.

It wouldn't turn cause of the 3/32" copper beads in the bottom.

Yeah, like the worst load regulation known to man.

Yes, they can be excited externally, and then made to generate power. But unless you want to run resistive loads only, and then with around 15% load regulation, they're not effective.

Besides, with that motor he had, he'd have blown a few hundred watts just in excitation losses.

NOT an effective approach, especially for someone who knows nothing about motors.

Take it to the scrap dealer, they pay out for motors.

Most definitely CAN be used as a generator. Needs a few good caps - and it needs to be a 3 phase motor to do it relatively easily.

Not true with 3 phase motor.

So, how would you use a three phase motor as a generator?

snipped-for-privacy@snyder.on.ca fired this volley in news: snipped-for-privacy@4ax.com:

and you need to not care about load regulation.

LLoyd

You put motor run (AC) capacitors accross 2 phases and take power off the third.. You need to run it just over nameplate RPM, start it with no load, and it automatically shuts down if overloaded.

On a single Phase motor you put the caps across the load.

I am very surprised to read about it. Do you have any kinds of references that I could take a look at?

So, would the same idea work on a 3-phase motor, with 3 identical capacitors, one per winding, and get 3-phase out?

That _would_ be cool. :-)

I don't like the load regulation deal, but I'm already thinking about some kind of regulation circuit - a shunt regulator could probably be made with a bridge and a mongo pass element, but that's terribly inefficient...

Google 'induction motor generator conversion' - there is a ham operator has a site up - and I think something like "otherpower.com" as well.
