Tinman's Rotary Transformer

[tim123]

Another pic to explain the Permanent Magnet idea I've been boring y'all with.

- It uses the same rotor / stator geometry I described previously.
- The magnets shown are only one of each pair - so the middle rotor segment can 'flip' from one polarity to the other.
- The rotor segments aren't shown in detail.
- 3 rotor segments must fit between each pair of magnets & their coil.
- The coil sees, (for example) NNS on the left, and NSS on the right...
- These flip to NSS and NNS as the rotor turns, and back etc...
- Every change in flux (that's harvested thru the diode) causes the coil to pulse a field which helps to turn the rotor.

I'm not sure it'll work at all:
- I don't think it would rotate if the coils were replaced with PMs, and the field was static. It looks like it should, but static magnets always seem to find a resting point, even if you can't imagine one.
- But, perhaps the pulsing of the coil would actually keep it all moving around...

Anyway, it's just an idea for people's entertainment...

Luc & Tinman,
  guys. For the *third* time  , the magnets are not attached to the rotor... The rotor segments pass over the magnets. The PM design is basically a self-running Ecklin-Brown type generator...

Sorry about that Tim, I thought the magnets were in the rotor because when TinMan wrote: "OK,about the PM's in the stator core. Im not sure why you would want PM's" ... you replied with the below

No mate, not in the stator... The rotor.

So I thought you were correcting him but I looked at your original post of your design suggestion of PM and realized I was mislead by your above reply to TinMan.

At this point I can't say I fully understand how your design suggestion with PM's would work, so please go on with your idea and in time I may get it.

Hi Luc,
  how's the houseboat going?

It's going well thanks. I don't know if you're following the topic on it but if not here's the link to it: http://www.overunity.com/13496/building-a-solar-electric-houseboat/msg360011/#msg360011

I don't think that this is right:

I think the idea of 'stored flux' in this case is just confusing.

The relationships involved are defined by Faraday-Lenz's Law:
http://hyperphysics.phy-astr.gsu.edu/hbase/electric/farlaw.html

VoltageGenerated = - NumberOfTurns x ChangeInFlux x CoreArea / Time

So the stator voltage and flux is generated in response to the change in flux caused by the rotor.

It all happens instantaneously (well, at the speed of light), so there's no storage...

I may not explain the effect with the correct terms as I have no formal education in all this stuff as I've been self teaching over the years as I experiment. So sorry about that.

Attached is (hopefully) a clear description of how the Positive Lenz effect actually works in the Rotary Transformer. To the best of my understanding it's correct, and logical.

Hopefully this should help de-mystify what Tinman & I are spending our time on, and it should help people design their own devices based on the principle.

It is my understanding that the amount of power available from the stator is defined by the physical size of the stator coils, and the amount of flux change...

I think that the Positive-Lenz effect is a clear route to overunity...

Sorry about that Tim...

No problem mate. TBH, I re-read my posts and I could have been clearer. Not sure it''l work anyway (but it might)...

I may not explain the effect with the correct terms as I have no formal education in all this stuff as I've been self teaching over the years as I experiment.

It can be really diffficult choosing the right terms and analogies when researching, and we are covering some interesting, and as far as I'm aware, newly noticed phenomena. I hope that the image I did gets to the heart of what it is we're observing... And I hope nobody objects to the term 'Positive-Lenz'... I just felt we needed a name for it. Am open to suggestions...

Will check out the housboat thread. Nice one.

Load on stator coils gives nice acceleration with diode
