Reactive Generator Research for everyone to share

Hi Luc
I'm not qualified to weigh in on the discussion going on but I have been playing with your circuit and found something very interesting. I'm not sure if it is explainable in electrical terms but to me it was a head scratcher.
The effect only happens within a 3 to 4 microfarad difference in capacitance on the input to the MOT. That is somewhere near the sweet spot that gives highest output power at the resistor.
What I did was feed the output of the MOT to the output of another MOT . I then took the input (115 volt)of this second MOT and fed it to a small induction motor paralleled with a capacitor.
Here's the strange thing.  When you load the motor or even stall it the watt meter actually shows a large decrease in watts being consumed, even on a dead stall. This effect goes away and increases watts in if you use capacitance that is below or above  the tuned value.
Is this normal or something that reflects this reactive circuit?

Hi Vince,

a motor is an Inductive load. I have written that once you connect Inductive loads (anything that has a coil in it) you will change the circuit.

When you connect a motor and hold the shaft the coil will remain at the same Impedance but let it go and now its Impedance will change and so will the circuit tuning. So that's why under most load it will use less watts.

It will take some time to understand Impedance changes.

There are ways to build a motor that will have next to no Impedance changes when the RPM increases. I have shared such a motor design some years back.

It will be adapted  to work on reactive power and will give out large toque as it only needs a small input power since most of the power comes form the permanent magnets. This Motor design has next to Zero change in Impedance, Zero cogging from magnets and all of magnet power is transferred to torque

All the best in your experiments

Hi All,
maybe you want to try this selfmade wide range changeable electrolytic capacitor:

I hope it can stand the used voltage...

Use 2 Aluminium foils or plates for the electrodes, so they can stand the AC .

Regards, Stefan.

Stefan,

The electric motor turning the generator head is not working on reactive power. So why would you need to check its phase, power and so on. It is connected directly to the 120vac grid, so the plug in grid power meter is quite capable of displaying how many watts it uses since it takes "normal" power factor into consideration.

You are either misunderstanding the DUT in the video or I don't understand how my circuit (connected to gen head) can have an Impedance match to the motor (connected to grid).

Luc

Hi Luc, well,
as it is an AC motor surely it is inductive to the grid and has a power factor which is not 1.
So please also show exactly the change in power factor at this drive motor,
when you apply the load at the generator output.

Please also put a incandescent lamp in series with the drive motor, so we can see, if this bulb
changes its brightness, when you draw power from the generator.

You really have to exactly look at the input of the drive motor, what is going on...

Regards, Stefan.

Stefan,

The electric motor turning the generator head is not working on reactive power.

Well , I disagree, when I am interpreting the Scope shots right...
In your first video
https://www.youtube.com/watch?v=Guc8TADLteM
at the end  at min 25:43
the drive motor used 137 Watts of total input power
and only 49 Watts  of this were REAL input power and the rest = 88 Watts
was reactive input power.

Please check this again.

Many thanks.

Regards, Stefan.
