The arm controls the RPMs? If thats the case, thats the ingenious part. Very nice.

@zer0dahero and others: yes, guys: that flexible wishbone which the lever-arm adjusts, determines the speed and direction of rotation. It is much like a steam engine in the sense that the contact-time, or dwell, of either half of the brush, is much like the steam engine's steam-admission time-per-stroke. That was Avery's innovation. The motor is adjusted by the operator very much the way a steam engine's "hookup" is adjustable. It makes the toy motor much more fun to play with, imo.

Thanks to everyone for the many views and for the kind words and votes.

What a beauty

[budsiskos]

it uses an electromagnet to move a metal piston

I just found one of these for 15 bucks, it still runs but needs restored. Thanks for sharing the patent number, I like having a 100 year old electric motor.

[seanflannes]

where did you get that ? it looks like fun



[RODALCO2007]

That is awesome !!

[jdflyback]

mine runs on 30 volts and it doesn't run as good as that thing that runs on 1.5.

[MucusFelidae]

Efficiency of that motor is not that bad, actually it is quite good, the frictional losses are minimal, what remains is ohmic loss in the coils which is unavoidable, and magnetic losses in the solenoid iron core which can be optimized by design.

Hahaha Ányos JEdlik invented the electric motor in 1827, However he invented a direct rotating engine without any pistons and arms :))))

[InquietudEterna]

That's elegance!

I have a crude antique toy motor that looks like this one only more of a toy maybe. Do you have any place to look up my old motor. It has no markings, just someones name on the bottom with a faint 1921 in pencil. I hooked it up to a 9 volt battery and it runs quite well.

[TheRebelman95]

how does the arm control rpm?

[TestECull]

It's the world's most inefficient electric motor!!!

I must have one. It's so cool.
