Using A Philips T581 Washing Machine Motor As A Generator

From your data it appears to be the single phase, reversible, capacitor start, dual speed type motor used in washing machines in the old days. Since it's got a squirrel cage, not much chance to turn it into a generator unless you change rotor with a PM or an electromagnet. But don't let the motor size fool you, it's a very low power motor, not worth the surgery. S.M.

Many thanks.

Thanks, I know the site - it's interesting. Do you know of any sites that list good motors for my project? I have heard about the computer motor drives (e.g. Ametek) and DC permanent magnet motors from treadmills. Thanks again.

Ebay is always a good source...

Wind Turbine FAQ

It can't be done without some way of generating a magnetic field inside it. So it isn't worth the bother. Try using a vehicle alternator instead.

Thanks. I'm going to look for another motor, probably from the local scrap yard. I'll take this motor apart for the copper wiring.

Two possible ways and there are a pack of videos on YouTube about how its done, is to find a car/vehicle Alternator of the amps you want and use it via your prime mover to generate 12 volts nominal (up to 14.5 volts or so) to charge batteries and/or convert to mains.

For a lower speed good output, many replace the wound rotor with a magnet, but now the output voltage is not regulated anymore and changes with the speed of rotation.

Go to a scrapyard and take one off a scrapped car. Older cars have the controller external to the alternator. Note the vehicle type and year to help if you ever need spare parts. The chassis number might be very helpful later.....
