Easiest way to make these motors generators?
« on: September 10, 2006, 07:36:45 PM »
There's a pile of good running motors at a local hanger...the owner wants them all gone because he bought a plane and has some notion about planes belonging in hangers.  I grabbed what I could with the time I had...only 2...lol


The first motor is a GE 115v 1/2hp 1050rpm 3-phase motor from a blower I think.


The second motor is GE 460v 25hp 1200rpm 3-phase motor from a large auger...big bastard, too.


I don't hold too high a hope of using the big one but it'd be badass if I could lol.


I know that the best way to make power from them is to put magnets in them.  I'm wondering if I can use smaller round magnets and more of them to achieve the same results as larger, flat/convex ones to build a charge?  No one near me has a mill and I can measure and mark but not groove propper slots for the magnets.  I can, however, drill any size hole.


On the other hand, I've heard it's possible to convert them to produce power by using capacitors.  How does this work and will it still produce power at low rpm?


Sorry if this is a frequent question...I've obviously not mastered the search feature here as I simply can't seem to find anything relevent to my project.

You can use the first one for a direct gried-tied system, the good thing about that motor is that it's 6 pole and therefore turns at a more reasnable (slow) speed.
