Reactive power - Reactive Generator research from GotoLuc - discussion thread

[gotoluc]

Gotoluc, have you considered trying an RC model brush-less motor? They make good AC generators as well. you can pair up a couple one mover/driver the other generator. They typically use speed controllers (PWM) to drive them. 3 wire output.

I was thinking that the magnet to coil angles might be off thus your dilema.

Yes, I did think of that but they don't output high voltage and the effect is much better over 200v

Thanks for your post

Hi TinMan and everyone,

you may have read that I've been saying this circuit is not creating energy. What I think is going on in this circuit is by separating the TWO components of electricity (voltage & current) you don't destroy the electricity (aka don't kill the dipole) by short circuit like typical everyday circuit we use.
When the electricity components are separated they can go through a circuit, do work and come back out with next to no losses if there is minimal resistance in the circuit.
However, you need something to receive the return and store it or convert it to something useful. I think this is what the Alternator Gen is doing. So timing is very important and I'm now starting to think that a permanent magnet alternator gen may not work as well as an exciter rotor field alternator gen like I've been using in my demos and now what TinMan is using.

Let me explain, for the past 3 days I've been busy converting a DC permanent magnet motor to an AC permanent magnet generator. It's a big job but I got it done and I was testing it last night and found the effect is not as obvious or as good as using an exciter field rotor generator.
When my series cap circuit is connected to this PM AC gen it's like something is out of timing!... I see the effect a little but it's like it's kind of having a fight inside the gen, like a motor out of timing. So I'm starting to think that the exciter rotor gen causes more of a delay then a PM gen and it could be this delay that makes the difference in helping the gen rotor to be pushed at the right time when the reactive power is returned.

More tests need to be done but I though I would share this new information.

Luc,

The big question as I see it, when using your original AC gen head, is whether or not your circuit actually provides no loading on the prime mover or does it just happen to reduce the no load draw of the gen on the prime mover by the exact amount that you are able to dissipate in your load?

There is a lot going on in the gen regarding phase angles in both the field and exciter circuits.  Particularly with a cap regulated unit.

It might also be reasonable to expect that there would also be a difference observed if a brushed AC alternator using electronic regulation were used instead of your capacitor regulated brushless unit (which I assume it is).

You might consider mounting your AC gen's regulation cap external so that you can probe what's going on in the exciter circuit.  It would also provide another dimension to experiment with.

Can you elaborate a bit more regarding your observations when using your recent PM alternator?  What exactly do you mean by "out of timing"?

As you usually do, keep up the good work,
Be safe!

Yes. I know that is the big question and one that I have had since the beginning and why I built a PM AC Gen.

No electronics. The DC motor conversion make a brushed AC gen

Yes, that could be something that could be done.

I can see the gen casing kind of rock back an forth. It's not smooth

That's all I can answer for now as I'm out to get some parts before traffic starts

Luc,

When I made reference to a "brushed AC gen using EVR", I was referring to the brush type AC heads typical of small AC generator setups that use regulation of DC to the rotor for field voltage regulation (as opposed to brushless cap regulated units), not your new PM alternator.

I have an idea : maybe the best way to measure input power would be just connecting DC motor as a prime mover of generator ? DC current can be very acurately monitored.
