I believe the D.C. capacitor would need 210 volts. I'm not sure if those kinds of power coils would resonate with the transformer in the way. This coil is extremely versatile because it can plug directly into a wall socket and run any N.S. rotor effortlessly with synchronous A.C.. We need more testing to determine it's value as an LC tank componant. It may help to wire the capacitor to the coil above the transformer at 21 volts. We would need to wire the DPDT switch between the coil and capacitor at the coil's electrode junction to disconnect the transformer. These turntable motors come in different power ranges. The copy models cost around $10.00 from ebay.

Disconnecting the transformer from the coil and pulsing the 1 turn primary into an LC tank consisting of the 10 turn transformer secondary and matching capacitor, tuned to a resonant frquency of 60 hertz, may act as an A.C. "Pony Tank" and feed power into the adjacent main tank inductor through induction.

The "Keppe Motor" can run as an A.C. synchronous, or D.C. pulse motor. Keppe has reported the same reduction of input under load as Gotoluc. Luc grabs ahold of the rotor axle untill it starts to slip, and measures a drop in input.

The slowed rotating magnets are forced to do work to try and catch up with the A.C. frequency. The permanent magnet's field is actually strengthened from the quantum plane to help the rotation get back in synchronicity with the A.C. frequency. When Luc squeezes the axle and causes the magnet rotor to begin to "Slip", the magnets really start growing stronger to help catch back up to the input frequency from the atomic level. This results in the reduction in input, and amounts to "Free energy".

The Keppe fan motor is an electronically commutated DC motor.  It will not run as a synchronous AC motor.

@MarkE,

Your block diagram above stretched the page! Please delete it.

The picture is 1262 pixels wide.

Unique Features of the Keppe Motor:

•Automatic dual voltage: can run on either 110 V or 220 V, or 50 Hz or 60 Hz, with no customer settings required, making it universal.

That is not at all unique. The schematics of the Keppe motor I reviewed would not even safely run on 110V.  220V would cause the electronics to catch fire.  I made specific recommendations for safety changes that they may have later incorporated.

•Can run on AC or DC, making the switch back to DC more achievable.

That's because there is a full-wave bridge rectifier and filter capacitor.  DC input simply means current only ever runs through two of the four diodes in the full-wave bridge.  The rectification and filtering means that it cannot run as an AC synchronous motor.

•The Keppe Motor runs barely 5º C above ambient, whereas conventional motors run as much as 20-60º C above ambient.

Anyone can make a motor run cool simply by oversizing as Keppe do.  What matters is how much power the motor wastes.  In the schematic above, Keppe ineptly get their low power setting with a wasteful power dropping resistor, when a simple multivibrator could have been used to chop current.

@MarkE,

I didn't say that the Keppe Motor was an A.C. synchronous motor. I merely restated what Keppe says; That "the motor can run as one" either on 110 V or 220 V, or 50 Hz or 60 Hz. 

Keppe are FOS.  They make a number of false claims such as resonant operation that does not occur. It is like all their utter BS about "disinverted physics". You didn't know better.  OK, now you do know better.

Keppe also maintains that the motor draws less input under load, like Gotoluc's A.C. synchronous job. I'm suggesting a common factor that involves a strengthening of magnet force from slip lag to account for the seperate but similar effects.

Well, the problem there is that Keppe compare their poorly designed, electronically commutated motor against extremely inefficient shaded pole AC motors.  A fair comparison is against other DC motors, such as DC BLMs.  Keppe do not want to make such comparisons because when they do, their crude POS motor comes up short.  The Keppe motor compares poorly against commercial DC BLMs that cost less to build, are more efficient, and don't constitute electrocution and fire hazards that the Keppe fan kit motor did as released a couple of years ago.

The Keppe motor is a very crude affair:  It has a single pole stator and a two pole permanent magnet rotor.  It throws away the stator magnetization energy.  The incredible part is that Keppe claim that it took them 10 years to build what has the sophistication of an 8th grade science project that disregards safety.

@MarkE,

Thanks Mark, the Keppe Motor sounds like just another piece of crap!

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

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.

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.

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.
