AC Permenent Magnet Motor

[gotoluc]

@everyone,

today I was experimenting with LOW FREQUENCY RESONANCE for the first time and I was able to get a coil to resonate as low as 17hz using sine wave. To get resonance this low I had to use two microwave oven transformer secondaries in series with a 10.6uf capacitor in parallel with the coil which are in total 7 Henrie's inductance and 146 Ohm DC resistance. Unfortunately I had to use the steel cores in the coil centers to raise the inductance to this level which leads me to believe that reaching 7 or 8 Henrie's without steel cores (Air Core) would take miles and miles of wire which would have too much resistance and end up being very costly and heavy

So It looks like I may not be able to build a resonating AIR CORE rotating magnet motor. No wonder Newman's motor weighs over a tonne

I'm quite positive that the effect would not be there using steel cores

If anyone has anything to suggest please feel free to post.

HI Luc
maybe superconducting wire

Have you any idea on what it takes to run a superconductor?

First of all......It's EXPENSIVE....did I say expensive...yes I did.
                    And it's very brittle and takes advanced machinery
                    to make any type of coil.....and it's EXPENSIVE.

Secondly......You need to cool it down to at least 138 degrees Kelvin and keep it there.
                    That's -135 degrees C or -211 degrees Fahrenheit.
                    This is neither easy or cheap.

Thirdly...........Superconductivity is sensitive to moving/changing magnetic fields.
                     So unless a very careful design it jumps out of superconductivity
                     as soon as the motor or transformer starts up.

However superconductivity is sensitive to moving magnetic fields so applications
that use alternating current (e.g. transformers) will be more difficult to develop than
those that rely upon direct current.

Gotoluc,
I quickly looked through this thread and watched the video. First thing that came to my mind was that this is very similar to the Newman motor.
