Look at this simple video:

http://www.metacafe.com/watch/665396/how_increase_speed_of_electric_motor/


Just repeated the experiment with my oral B electric tooth brush.  The frequency (or the sound from the vibrating brush system) changed with the approaching of a strong magnet.

So there is nothing revolutionary with the Thane Heins discovery???

Lawrence, you're showing your ignorance again! Your knowledge of Physics is elementary at best and your knowledge of magnetics and electronics is at the grade school level.

The moral of the story is don't believe everything you see and certainly don't jump the gun in announcing a great find to try impress others you're on the 'leading edge' in understanding these great OU findings, including such home made flying saucer experiments from your commie friends.

Haven't you been laughed at long enough and by more people you can even count? I would have thought you would have learnt by now about not teaching your nonsense on this and other forums, eh?

cheers

@chrisC

Never forget that a stopped face clock is correct twice a day.  ;)

I gave up on that so called, "lead out theory," long ago when I looked into the "simple" pendulum example.  I recall that I could not reconcile even the most basic premise due to a lack of clear system definitions.  I only check in on that topic nowadays for a quick giggle.  :D

That said, I happened to notice a motor acceleration myself a while back.  I was using a small DC motor and a battery as a sort of a poor man's 'spark gap oscillator' to drive some current around a coil of mag-wire wrapped around two magnets super-glued together in an opposing configuration.  Part of that experiment had something to do with making CD music sound 'different' somehow when this 'radiant beam' emitted from the magnet centers was left on the CD for some time.  There were some other things going on with that experiment that escape my memory at the moment, but I digress.

At one point in my screwing around with that particular experiment I happened to attract/attach this small motor to the magnet.  I noticed that at certain positions I could hear the motor speed-up.  I thought it was due to the opposing-fields-radiant-energy thing.  However, after seeing the video quoted above in this reply, I wonder if it was not just the magnets alone that were accelerating the motor.

At any rate, you might not want to throw the baby out with the 'lead-out' bath water just yet.  I am sure that a bunch of folks here have magnets and small DC motors lying about.  Why not give it a try?  8)



UPDATE: I just spoke with jdo300 about this.  He said that placing magnets near a DC motor will increase the speed because, if done right, all we are doing is increasing, by augmentation, the strength of the magnets already inside the motor.  Jason also said that Thane is using AC motors and that this fact is what makes his results such a curiosity.

Sometimes I feel that my only purpose in posting here is to make others feel smarter.  ???

Hi this is my first post here. I know very little about motors and generators.  I would like to know if this quote supports the hysteresis explanation?

Heins realized what had happened: The steel rotor and driveshaft had conducted the magnetic resistance away from the coil and back into the heart of the electric motor. Since such motors work on the principle of converting electrical energy into motion by creating rotating magnetic fields, he figured the Back EMF was boosting those fields, causing acceleration.

But  how could this be? It would create a positive feedback loop. As the motor accelerated faster it would create a larger electromagnetic field on the generator coil, causing the motor to go faster, and so on and so on. Heins confirmed his theory by replacing part of the driveshaft with plastic pipe that wouldn't conduct the magnetic field. There was no acceleration.

Hey guys and girls,

I'm reporting back as I said in Reply #21.

I live in Ottawa and have known Thane Heins for about 9 years now but have lost touch with him for the past 7 years. However I talk to him on the phone tonight for about half an hour. I invited him to the O.U. forum but he said he would not have the time to get involve at this time.



Hi Luc,
many thanks for contacting Mr. Heins.

Did he say anything about his overunity transformer
and if the shown videos were still from an earlier development
stage ?
Does he now have better units and videos ?


Looking forward to a report from the upcoming
university demonstration
Many thanks.

Regards, Stefan.

@All,

Just want to say that tests done on MY pulse motor gives the oposite result as stated by DMBoss!

When I run my rotor and put a unshorted (open) coil (with a ferrite core) up to the spinning rotor then
the RPM stays almost the same. When I short the coil and put it up to the rotor the RPM is going DOWN!
A shorted coil is a break for the rotor.

Groundloop.


Well Groundloop:

You are comparing apples to oranges!  Exactly my point in chiding people posting results without doing their homework!

Ferrite cores, have exceptionally small core loss per pound of material and are virtually non-conductive so there is almost no eddy current loss.  And that's why we can use ferrites for extremely high frequencies, and cannot use steel above 400 Hz!

it's because steel, has very high core loss and so can't be used at higher freqs.  Not only is your test irrelevant to the issue at hand, i.e. Heins used bulk steel blocks as cores and you used ferrite (one has 15 watts per pound core loss at 60 Hz and the other has a few tens of milliwatts per pound at 60 Hz), But you fail to grasp energy/power balances!

Just because the rotor speed falls does not tell you anything about what and where power is going!  If you had a few turns of heavy wire on that shorted coil with ferrite as core - that would make a LOT of current and then the I'2R of that coil could be 20 watts!  This by itself with slow the rotor down, irrespective of a core loss change.  So you could have really large coil heating output placing a load torque on the rotor in excess of the miniscule core loss change of your ferrite core.

To make your blanket statement with authority, you'd have to measure torque, speed, True Power, and Rms voltage and current and crunch some numbers.  You'd also have to know the rotating mass friction at particular speeds being measured too, along with coil's DC resistance.

If however you had a gazillion turns of really fine wire as it appears Heins has, and shorted them, a miniscule current will flow and only a few tens of milliwatts will be dissipated by the coil heating, and the very large core loss change will be evident in rotor increase in speed!

To spell it out for you:

Your improper comparison using ferrite core, has a teensy core loss reduction upon shorting the coils, and this core loss reduction in drag, is less than the increase in drag due to the I^2R output of the coil heat. (yours is teensy because a 90% reduction in a core loss that starts at only 100milliwatts is teensy by comparison to a 90% reduction in steel core loss that starts at 5 or 50 watts!)

Heins' system has solid iron or steel bars as core, with a huge core loss value.  he also used a LOT of really fine wire to wind his coils - he shows one having 175 ohms DC resistance!  This miniscule current will flow to completely take the B in the core down to near zero as evidenced by the near zero voltage induction value.  So say he has 50mA flowing - into 175 ohms - that is then 437 milliwatts of coil heat adding drag to the rotor.  But he obviously has anywhere from 50 to 300 watts of drag in his system at no load, a large percentage of that being core loss - so if core loss were even a mere 5 watts no load, and it dropped to 1 watts when coils are shorted, the rotor will speed up because this lessened drag of 4 watts, is 10x higher than the increased drag from coil heating of 437mwatts!

Sorry your argument is nonsense.

Speed increase? I can see that.

No matter how much I dig I haven't found anything about shaft output power increase. If it is out there someone please post a link.

Thanks,
