@MarkE,

Thanks Mark, the Keppe Motor sounds like just another piece of crap! Look at the perpendicular toroid coil orientation to the N.S. magnet faces in this 14 volts at 20 hertz "Synchronous Motor" video. This video shows how the turntable coils need to face the diametric tube rotor:

There's a transformer built into the turntable coil that does nearly the same work as the "stand alone" model in Kim's video.

What they were marketing a couple of years ago would never get past safety agency requirements in the USA.

The motor in the video is very primitive, and one of the results is that it does not start by itself.  That's one of the reasons that the Keppe motor has a bias magnet.

@MarkE,

Good point! "Retod Dave" has his 'De-gauser Coil" powering his sinusoidal wave spinner lying down, 90 degrees from Kim's, the way the coil is oriented toward the tiny magnet rotor in the turntable motor case . This orientation would allow multiple coils to slip over a narrow tube rotor the same diameter as the turntable rotor magnet. Collaring a tube with 6 or 8  turntable coils in parallel ought to deliver much more increased torque to the axle.

Multiplying the coils would permit the use of a larger matching capacitor and strengthen the resonant oscillation. We can leave the original coils in the cases, then stretch a narrow magnet tube maybe 6"s, and completely encase the outside with a solid ring of back to back coils.

Resonance is not generally helpful in a motor.  Feel free to put together whatever you like and measure the efficiency with a high and a low Q configuration.
