What can i do with this motor? Answered

Picture of

I've had this motor in my house for the last month and i don't know what to use it for. Any ideas if i can use it as a generator or something else?

I think that motor would work well as doorstop, or maybe a paperweight.

I don't suppose you'd be willing to let us know more about this motor?  Like how fast it turns? What kind of power it wants?  What kind of motor it is?

Even a clear picture of the little label, or the specs on that label as text, that would be helpful.

this is what the label says:
part no. 3349643
E113 model c67pxegm-3482
H.P. 1/2 volts 115 Hz. 60 amps 9.3 rpm 1725

it also says it's a washer motor

In that case, this may not make a good small-project device, but something like a filament extruder (if geared down a LOT), winch, stuff destroyer, etc. would be pretty in-line with the kind of force you'd get. This motor is REALLY powerful for small motors, sort of at the bridge of little motors and the seriously powerfull stuff.

I think this means your motor is a single phase induction motor, with a capacitor and centrifugal switch used for starting.

I am not intimately familiar with this particular motor, but a Google(r) Image Search on "washing machine motor wiring"
turns up a bunch of pictures, and I am guessing the one I have picked out and attached here is something close to wiring for your motor.  I mean you'll have to probe the thing with your multimeter to see if those windings, capacitor, centrifugal switch, etc, are in the same place as on the diagram.

I think for a typical washing machine motor, there is usually a way to switch the direction it turns. This is true since, usually, the washing machine's transmission is made to do exactly two different motions, agitate and spin, depending on which direction (clockwise or counterclockwise) the input shaft is turning.  The second picture I attached is related to this direction changing wiring.

Finally, I have heard that wiring an induction motor as a generator requires a little bit of voodoo, or perhaps black magic.  The reason for this being you need AC current flowing somehow in the rotor windings, which of course are not connected to any wires on the outside of the motor.

Somehow the currents in the rotor windings must be induced there, somehow.  But how does that happen if initially there is no current in, and hence no magnetic field from, the stator windings?

I am not going to attempt to explain this particular voodoo myself, but fortunately a Google(r) search on  "induction motor as generator"
turns up a bunch of stuff, including some YouTube videos, which is good for those black magic kinda things for which you wonder if it's really possible.

Also for the induction motor as generator problem, this pdf,
looked like a good one.

You could run a washing machine with it (or a dishwasher, unclear)...

You can make it plug into a regular wall socket and turn at 1725rpm at about 1000 watts of power (fairly useful).

You could make it into a pump, or a fan, or a piece of machinery that needs to move. It won't make a good car or bicycle motor because it needs AC 110v power.

A) have you tried using it at all yet, even just turning it on? It looks like its wither encoded or a stepper motor.
B) do you have any documentation, pinout, specs, etc? that would help
C) How big is it?

A) no, i haven't tried using it, don't even know how to turn it on
B) i don't have any documentation
C) 14.2cm x 14.2cm x 14.2cm

Do you have any numbers on it? try looking those up, or measuring resistance across leads. If two pairs have a similar resistance, it may be a stepper, if one lead connects to two others alternatingly as you turn the motor, it;s probably encoded, and if the shaft is not somehow connected to the windings, it's probably AC.

Your best bet though is to look up the numbers.
