Here's a homemade variable inductor for A.C. current. Two of these variable coils in parallel, facing one another, would power the spinner with a sine wave coupled to a variable capacitor to control the resonant frequency!

Naturally, a battery and potentiometer would replace the A.C. signal generator after the variable capacitor was connected.

Any two solinoid coils with sliding steel cores connected in parallel and wired to a butterfly capacitor should be able to run a diametric spinner between them with the LC resonant sine wave. Pushing the steel cores in and closing the capacitor plates would lower the frequency and R.P.M..

Increasing power input to the capacitor, would increase the amplitude of the LC sine wave, strengthen the magnetic field of the coils and add power to the spinner, but the LC tank resonant frequency would still control the R.P.M.

3000 R.P.M. with a finger flick? Scaling harmonics!

The contradiction of this sine wave motor is that speeding it up would force the operator to turn the power down!

Why do you think that is a contradiction (sic) paradox?

"Another method to control the inductance without any moving parts requires an additional DC current bias winding which controls the permeability of an easily saturable core material".

So we can regulate the parallel coil inductance by wraping the core materials with seperate D.C. windings. This "Magnet Amplifier" circuit would permit us to finely tune the D.C. power exactly to each coil to achieve LC resonance with a seperate potentiometer and battery source.

Three knob controls. This motor will only run in resonance, but be very close to 100% efficient.

Here's a picture of four variable Inductors. Two variable Inductors in parallel can power the spinner from the LLC sine wave from a variable capacitor matching impedence. We should be able to control the frequency and R.P.M. by increasing or decreasing the Inductance and Capacitance, thereby altering the resonant frequency.

Those sure don't look like "variable inductors" to me. Unless you want to try varying their inductance by using an external magnetic field or something.

Here's one simple type of _actual_ Variable Inductor, called a "loopstick". The ferrite core is able to be adjusted in and out of the center of the Litz wire windings.

@Tinselkoala,

Gotoluc experimented with that coil in his "allcanadion no bemf" video. The coil has an "H" bridge and indeed comes with a magnet attached.

Two of your Variable Litz inductors facing one another in parallel should be able to power a bi-polar magnet spinner in between by sine wave. A butterfly capacitor, tuned to a fequuency low enough to start the magnet with a finger flick should be able to power it with LC resonant sine waves from a sufficient D.C source with no electronic componants.

To sustain the oscillation:
 
 "Make the L of the LC resonator the secondary winding of a transformer and couple energy into the LC resonator by driving the primary winding of the transformer at the resonant frequency. If the Q factor of the LC is large, only a small driving signal will be needed".

Pulsing a primary at the resonant frequency will sustain the oscillation more efficiently then adding power to the capacitor. The saturatable core wraped with a D.C. "Mag Amp" coil, can act as the "Transformer Primary" and sustain the oscillation with minimum input, if pulsed at the resonant frequency rather then topping the capacitor off from the losses. We can upgrade the circuit to supply a variable frequency range. The primary coil can both raise and lower the saturation level of the core with D.C  and efficiently pulse at the resonant frequency simultaneously to sustain the oscillation and save power.


@Tinselkoala,

What is inductance range in Henries of your variable Litz Coil?

@Tinselkoala,

You could seperate the Litz wire coils and designate one the Primary and the other the Secondary. The Secondary would serve as the Inductor in the LC tank, while the Primary's pulsed with low power D.C. at LC resonant frequency to help sustain the oscillation. The A.C. sine wave from the resonant oscillation powers the spinner, not the D.C. pulse.

The Seconday coil should easily tailor with the correct capacitor to deliver any Hertz and R.P.M desirable using the LC calculator. Gotoluc powers a large magnet rotor with a measly 28 milliamps. The Tank Oscillation should be able to transform at least that much current into fluctuating field strength from a battery.

Tinselkoala has apparently chosen to ignore me. He once again has proven himself completely worthless for any kind of constructive dialogue. I plan to ignore him completely from this point forward.

Two coils built just like this in parallel is just what we need, connected to a variable capacitor: The more the ferrite core's inserted into the coil, the higher the inductance and the greater the matching capacitance needed from the butterfly to lower the frequency of the LLC tank oscillation.

Wraping the end of the ferrite core with a Primary coil and pulsing it with D.C. at resonant frequency supplies the design with a second avenue for input to sustain the sine wave oscillation; A great efficiency improvement.

Always wondered if Teslas electric car motor had a resonant freq, and possibly built to be so. It was claimed to be an AC motor. So I wonder what the effect would be on the output if the motor windings were in resonance with input.

Nobody has ever missed anything important by ignoring YOU.

You are the one who constantly misrepresents the work of others, and you just posted a photo of four FIXED INDUCTANCE chokes and called them "variable inductors". Leave me out of your ignorant fantasies and false statements.

And if you were paying attention at all you'd know that I have already shown the value range of those loopsticks and incorporated them in various tuned circuit designs that actually work. And they can be looked up on the internet as well.

Ignore these, idiot.

@Tinselkoala,

You just called me an idiot. I don't want you reposting on my thread. Your're just a stinking fraud. You can't SIMPLY tell us what the "Inductance range" of your loopstick is. You're asking us to agonize through nine of your tedious videos to find out. The coil I showed uses the same thickness wire and wraping style as the A.C. tube spinner video, and the ferrite core is very thick and highly saturatable. Turning the bolt moves the core in and out.

Litz is just more "Hocus Pocus" from you phony disinformation artists. The "Loopstick's" just another piece of crap. The core is too thin to do anything practical.

The best approach would be to "Mag Amp" the core with a D.C. primary winding. This is an inefficient method, but allows for a reinforcing pulse at LC resonant frequency. Saturating the core wih D.C. current eliminates any inductance value to the coil. Placing magnets in a coil core alters performance compared to air. Saturating the ferrite creates an electromagnet. Adding inductance by reducing the D.C. current would be matched by increasing the capacitance to slow the rotor R.P.M.

Air has greater inductance value to the coil then a saturated ferrite core, or permanent magnets. We can precisly control rotor speed with this "Mag Amp" core saturator primary wrap, maybe a few hundred turns of 28 gauge. This creates an additional pathway for pulsed D.C. input.

The D.C. pulse should be able to spin the tube rotor at high power alone from the same source battery that charges the tank capacitor. The core saturator would be powered by the same battery. The core should be set back away from the magnet rotor, it doesn't need to extend completely through. The core would retract all the way coupled with reduced capacitance for top sine wave R.P.M. This speed up would be coupled with a reduction in input.
