Anybody who is paying attention still to this thread should now see the concerns of the author. He's nothing but a low life racist who has no ability to speak of.

Thank You Tiny for showing us that.

Babu,

So you are from India. Tell me, is it really that you worship cow? Here's my cheeseburger. You wanna bow to it?

[Matthew Jones]

Keep it up your fans want more.

I don't have a problem keeping it, though I speculate you do. You go around pontificating and acting like you're some sort of genius. You're just a man, just like everybody else, you're not special. You're just average, so knock off the high-handed behavior, trying to browbeat people into submission who disagree with you with your over-inflated ego. Contrary to what you may believe, you're not a god. Neither are you a guru.

You forget Tiny you started this. All I did was comment on your post. You could have just left it alone but you went on and changed the post to try to make me look bad. Then you went on and got racist.
Don't be jealous, I actually did the work to get to the point I can say I know what I am talking about. You can belittle all you want in your mind but the evidence (and searching the board will give you that) says I do know more, you post videos and speculate. Why? I know why.... Your dime a dozen but most people like you in past had humility admit what they were or what their situation was. You your a punk, like all racists and chauvinists.

So for now all you future posts get questioned. Or you can just blow up and show your colors.

Babu,

The tedious part of this whole interaction with you is having to read your boring posts.

Actually, I didn't start anything. You started it. I simply stated that I wasn't interested in you or your opinion, but your little, fragile ego couldn't handle that fact, so you thought you could be a bully, which is your normal modus operandi in dealing with people who disagree with you, but I proved you wrong.

You calling me a racist is a joke, being that you are from a country full of racists. Worse than racism is your caste system in India, which is based on racism. Ever notice how those at the highest level in the caste system are light skinned while those at the lower levels of it are dark skinned. Not racist, eh? Truth be told, the society that you hail from is extremely racist. It goes by a different name, called casteism.

You started name calling first. What's the matter? Can't handle "Hadji?" That's like calling me John or Mark, but because I call you Hadji or Babu, or insult your religion, I'm a racist? Yeah, right, give me a break. You're so insecure, as evidenced by you playing the victim.

Just for that, we having a few sirloin steaks tonight.

Shorting Stator Coils

Just reporting on a video.

Though not regenerative acceleration as far as I can tell, coil shorting does produce a noticeable effect.

You're right. Not regenerative acceleration, what ever that means. It is simple field weakening. He calls it a shunt motor so I assume that is what the nameplate reads. He wires it up as a series motor; ie. field is in series with the armature. So when he places the bulb (and diode) across the field, he diverts current around the field and causes less field current therefore less field mmf, therefore less flux, therefore increase in RPM. Also the shunting of the field lowers the voltage drop therefore increases the armature voltage causing increased RPM. Not out of the ordinary here.

When I first heard the term of regenerative acceleration I thought it might be due to field weakening, but it really didn't fit the description of the PM machines used for those demonstrations. Neither did the saturation theories I saw. But the vid in post #24 by Gestalt makes it clear what was happening in his demo.

Nothing remarkable.

I am the debunker, and yea I did that. The results are the same as with a standard coil as shown in my video.

https://www.youtube.com/watch?v=kfRxsC9yumQ

The Regen acceleration is REAL and gives the illusion of increasing performance

My theory as to what is occurring is as follows. The high voltage (~1.2kV) on the open bifilar config causes an electro-static current to flow between the windings causing a substantial open circuit back-EMF. Then when shorting the coil the high voltage goes to zero and the artificially induced electrostatic back-emf goes away. As load is added regular back-EMF from actual current in the windings occurs demonstrated by the increasing Pin.

The novelty here is that an OPEN coil can cause unusual amounts of back-emf under HIGH VOLTAGE circumstances. This is clearly seen when doing a comparison of power input numbers when the coil is NOT bifilar, and there is no bifilar in proximity to the rotor. This is something Thane has never shown and why he is in error.

Gestalt, High inductance coils are not required to get the speed up under
load effect. I recognized why the setup of Thanes behaves as it does and I
set about showing the effect with low inductance coils.

What I think is happening is similar to your explanation except that I don't
consider that the voltages produced would be very high, but high enough.

Basically all that I think is happening is that the open coils create a
significant artificial/parasitic load for the prime mover due to the coils inbuilt
capacitance, the same can be achieved with a regular capacitor connected
across the coils sized so that when the rotor is sped up the coils are excited
at a harmonic frequency of their resonant frequency or their actual resonant
frequency. That causes large currents in the coil which causes a large
Counter/Back emf, when the coil is shorted or heavily loaded the large
currents becomes small currents or the phase is altered and the Counter emf is reduced so the
motor speeds up. It's not rocket science and not even novel.

It's just silly.

Fist video is the main clip, part two, second video is a short version, third is the
setup Part 1. And also a different setup is last just to show if we know how it's done we
can do it with just about any setup.

Setup

Pulse motor as prime mover.
https://www.youtube.com/watch?v=YpKZw15A41Y

When the Speed of the rotor causes the rotor magnets to excite the coils at
or close to their resonant frequency or a harmonic of it then the coil
develops "tank currents" which cause a significant Counter/Back emf and
artificially and parasitically load the prime mover. A heavy load or a short
causes these currents reduce or change in phase.

The main thing is that setting a base line is just silly what matters is if the
setup puts out more energy than is supplied to it. None of Thanes setups do
that, he just fiddles the books, or Fudges the measurements.

The input should be the energy consumed by the Prime mover. and the
output is the actual utilized energy.

No need for baselines.

..

Basically as I see it, it's either a ruse or Thane is deluded.

Coil Shorting : Effect of Diode

Just reporting on a Video.

Okay, people, what is your explanation for this effect?

Farmhand,
When I began looking into air core coils, I felt it was important to establish a baseline. Otherwise, how could I know if there was anything to your statement that the coil as a capacitor was slowing down the motor/rotor, and what we were seeing when the coil was shorted out was just the motor speeding back up to where it should have been in the first place? We need to KNOW what the performance is with no coil in sight, do we not? And isn't that the essence of a "baseline"?

So I spun up a rotor connected to my motor and established a baseline for volts, amps, and RPM's using a 60 volt power supply. NO coil involved. Then I introduced an air core coil to the rotor. There was no change to the amp draw, voltage, or speed that I could detect with my meters. Then I connected a load to the coil. In the case of the three coils I am presently working with, there was a slight increase in the RPM's of the rotor (only about 12 RPM on the specific coil I am thinking of....don't recall the others, but they ALL sped up), and a slight decrease in the amp draw. With other coils I tested there was NO speed up under load, but neither was there a slow down when the coil was first introduced to the rotor. I would not say this is conclusive proof, but in my mind it is a basis for further exploration. That is why I am spending the money to construct a precision coil testing setup so that I can use scopes with the proper connectors to measure the coils as accurately as possible. I want to take out as much of the guesswork from this as possible. Without proper testing, all we are really DOING is guessing.

With coils that HAVE cores, you should test without the coil present because OBVIOUSLY the magnets on the rotor are going to be attracted to the core of the coil, so you need to see your data BEFORE a specific coil is introduced, otherwise you do not know how much a particular kind of core slowed the rotor down or increased the amp draw on the motor, so IF it speeds up, you have no data to analyze the relationship between how much it slowed the motor down and how much it sped up under load. Baselines are NEVER a bad idea. They are the basis for scientific testing of all kinds.

BUT, I do agree it boils down to input vs output. It doesn't matter whether the motor speeds up or slows down. What matters is how much power did it consume to run and how much power did it generate. Can you get the output of five or six times the input you need be able to loop the system.

armature field

Just reporting on a Video.



Electric OU: Coil Shorting Shunt Motor 2: Effect of Diode - YouTube

Okay, people, what is your explanation for this effect?

Slightly more interesting than the first one. Here the armature in the unexcited stator field does produce a flux with the armature current. When stationary there is a net zero flux through the stator and therefore no torque hence no rotation. When twisted by hand the armature flux becomes distorted in the field (stator) structure and establishes a flux field to interact with the armature current and produces torque, hence rotation is sustained. This armature induced flux is weak compared to the main field flux one would have with an excited field and so the torque in this mode is barely enough to maintain rotation at no load.

The effects from shorting the field and doing so with a diode, I suspect, is aiding or hindering this weak armature field by establishing a current in the field coils due to a transformer effect. The diode rectifies the induced AC in the coil. One polarity of armature excitation, that aids or increases flux and produces more torque causing acceleration and reduced current (higher BEMF). The other polarity, it reduces the flux, torque is lost, nearly stalls and current increases.

Putting a scope on it would verify that.
