Microwave oven fanr as pick up coil?

[sm0ky2]

the AC synchronous induction motor already comes "as is" functioning as a generator.

The output at the two electrical terminals (when the rotor is spun by external force)
  is AC, in a perfect sine wave. these make great generators, which can be attached to a windmill or water wheel or anything that can turn it.
you can take it as AC, or rectify it to DC.

The field is self-induced, meaning they generate more electricity under heavy load, and at higher RPM.
placing a magnet onto the metal-plates (anywhere really) induces a biased magnetic field, which will magnetize the rotor at lower load and rpm.

if you wanted to use this as a "pick up coil"
[im not sure I completely understand what you mean here, but i'll give it a try]

you could remove the rotor, and replace it with a rotating magnetic field, or another rotor, with actual magnets on it.

But, the way the plates and other coils are designed, the best rotor, will have magnetic fields that look like the spiraled lines on the existing rotor.
If you could simulate this orientation, either with magnets, or with an electric field - then what you are talking about, should be possible.


if you just wanted to use the coil, and the inductance of the metal plates,
you could simply just place the coil-side of the motor towards your changing magnetic field that you want to "pick up".
the resulting signal will present itself across the terminals.

Yes, i know, but i wanted you to know where i got them from, so it may be easier for you to help me.

I haven´t yet found how to wire these up as pick up coils.

Thanks for the response.

there is only one coil that you need to worry about. there are two wires that come out. if you turn the rotor it makes electricity.
if you put the coil near moving magnets it will do the same. but remember you have big steel plates, that will attract magnets

the other coil on the transformer is just used to bias the electric field so the rotor can turn. this is a thick copper wire wrapped around the steel plates.
the plates are actually laminated, there is a tiny gap between each one, which makes the total field stronger, than just a metal block.

Hi mr smoky I have an old sync ac motor you show, i put it on my drill and spun it I get nothing,  have A look at this video.

What i mean when i say "pick up coil", i mean, as i understand it, a "pick up coil" is collecting energy from a moving magnet field.

I should really link to Anguswangus video, but i cant becouse i am using my phone, and i havent figured out how to do this yet.

Anyway, thank you.
