Tesla Car and his nephew

[Farmhand]

Sparks and I replied at almost the same time.   Yeah I was thinking about rewinding one and I cut the thin wire off it but then I got sidetracked. Again.
I've got a couple of old twin tub washing machines and I can see one of the small motors in one looks like a similar motor but more like a normal motor, it's all open though I'm hoping to get it out tomorrow. It looks interesting.

Yes, I just had seen that Sparks posted too. Thanks Sparks,

Hey Farmhand

There may be other parts in the motors that are say Tuned for 60hz, but the first thing that I see easily is the input stator coil. Like a large inductor for a woofer in a home speaker cabinet. It doesnt let high freq get to the woofer. So I can see already that this coil would do the same. Im grabbing my motor tomorrow.
Found a bit more on the shaded pole stuff. The wiki is not definitive enough for me.

Makes me wonder how many shades there could be to make it better, or worse.

I think we're missing the bigger mystery - that of Tesla's time machine.  How else did he obtain 70L7 vacuum tubes - not invented until 1939 - for use in his car in 1931?

A vacuum tube and a vacuum capacitor (tesla's invention) look curiously similar to the casual observer.
