Scavenging motors from washing machines

Here’s a useful tutorial on how to harvest a motor from a waching machine, including a section on how to use bridge rectifiers to produce DC from an AC motor. Supposedly these are ideal for driving wind generators, so check out your wind exposure, make an inexpensive generator, and start charging some batteries!

    Sadly, this is only relevant if you live in tha-down-undah.
    Or get really dang lucky elsewhere.

    One of the key selling points about the motor for these machines is the fact that it uses 42 coils, which allows you to rewire it into a 7-phase power generation system. This reduces cogging losses, and obviously, increases efficiency.

    Otherwise, its just another run-of-the-mill permanent magnet generator. :(

    Hm…I am the appliance tech/repair guy at a 750+ housing unit retirement community, with washing machines up to 19 years old. I have never seen such a motor setup on a washing machine.

    I will study the newer ones under repair to see.

    that if someone throws out a washing machine, it’s because the motor has problems. But if not, sweet!

    That it is more likely a timer or solenoid problem, or a leaky joint or hose that gets them thrown away. Or the fact that they are out of fashion, the wrong color, banged up, or use too much water.

  5. Randy Breckenridge says:

    Does anyone know what kind of motor is pictured? I could really use some coils like that. Anyone know where I could obtain coils like the ones pictured?
