Mostly PM motor - Joe Flynn motor. My attempt to replicate

[Ted Ewert]

Whoa.....That got my wheels turning........hook me up if you find it before I do.......

edit....

Which inductor characteristics are you referring to? I am thinking that there are already several materials which fit the bill if we are simply referencing the inductors charge/discharge characteristic.....

Regards

I'm talking about something that will change the phase relationship in a magnetic field, like the inductor, or capacitor does to an electric field. Some form of static physical configuration which causes the same effect as motion does.
Just as voltage travels through an inductor instantly while current lags, whats the corollary that would make magnetic force travel faster (or slower) than magnetic current?

Where do you find this schematic?

DrMabuzo, What exactly do you mean?

I fixed the bearing problem and the motor runs much quieter now. I put one magnet in a 90 degree angle by accident. It is interesting that the motor runs anyway, but it consumes two times less current, but also the RPMs and torque gets lower.
Thats all for now.
Thank you!

Just made a better solid state setup with silicon steel laminate bars and neo magnets. I used 0.35mm diameter wire and put on 5 layers on each bar. I hoped that more turns would work better. Now there are about 1800 turns combined. But the thing is that I can turn my power supply up to max - 30V and at that voltage it consumes about 0.4A and one of the end pieces gets weak enough to pull it off, but it does not fall by itself. So I guess I need higher voltage, but anyway, if it consumes 0.4A already at 30V, then at higher voltages it would consume even more and that is not what I want. This is odd.
In this video:
YouTube - Parallel path con un delta di 370kg
The guy can redirect the flux flow just with a small 3v battery. My magnets are bigger, but I don't think that is the problem. I will post a picture of the setup tomorrow

Hi Jetijs. Gays on YouTube use smaller magnets and thicker wire and that is important. In your setup you use many turns of thin wire and in same time you have lot of resistance. Of Course you mast use high voltage to create enough current in coils because you need same strength as your one magnet
(ampere turns) to create parallel path effect.
And coil resistance is sum of R=R+Xl where Xl is inductive resistance.In parallel path static device you have lot of inductance (L) which depends of coil dimensions , magnets strength , and cross section of steel bars (saturation). I suggest you to use thicker wire (less turns) and smaller magnets.If you don't have smaller magnets you create a little air gap between magnets and steel laminates with piece of plastic (0,2-0,5mm).

Flyn PP MEG.

There's some good discission about the Flynn PP on the Solid State Orbo thread at Overunity.com. I am testing an Ossie Callanan type flux modulator right now, and plan to demo my results on youtube. Ossie has three new youtube videos on his coil wraped barn wire toroid. My version is a spiral pancake version with a reverse wrap, so both ends of the wire exit the same side of the coil. This pancake coil is designed to fit centered between an even number of disk magnets, that together act as the middle magnet in a three magnet Flynn PP array. Charging the copper magnet coil wraps negates the attraction of the steel wire core and links the magnetic flux between the magnets on either side. The center disk magnets may have to be slightly larger to equal the strength of the side magnet stacks when the pancake's charged. Imagine how this flux switch might be used to activate the unidirectional field of a Hallbach array. I enjoyed the Jetijs build alot.

zhorv324, thank you for the suggestions. I spent 6 hours to wind those coils nice and tight and now it is all for nothing
I will rewind the thing with thicker wire. Here is the setup:



Those are 1" cube magnets

Sorry Jetijs but magnets a really to big and core go to saturation and you need more current (ampere turns). I think if your magnets are 2,5cm cube , cross section of the core must be at lest 12cm. Remember 3x flux, and cor goes to saturation after 1,8T. If your magnets have 1,2T (N35 grade) result is . Sorry for your time but **** happens . God luck with winding AND yes setup is nice as always

[Jetijs]

zhorv324,
do you mean 12cm or 12 cm2? What do you mean by 3x flux? So those magnets are 2.5x2.5cm that is 6.25cm2 square area so I need double than that to be sure (12cm2)? Also I have those huge neo magnets that are 2.5x2.5x10cm big and N48 grade. They are magnetized through thickness so the poles are on two of the larger sides. So the pole area is 25cm2. So what should the stator core square are be to use these huge magnets, is that even possible without core saturation?

[zhorv324]

Sorry my mistake, 12cm2. And about 3x flux ,when you divert flux to one sade off parallel path device ,you have sum off 3 flux . Two off magnets and one off coils. This is only maters in static device because you don't have air gap in setup. In parallel path motor things change , because you have 2 air gaps between stator and rotors pols. From my experiments I conclude that in motor you must have at least same cross section in cm2 in magnets and stator section

[Jetijs]

Ok, thank you for clearing that up

[zhorv324]

What I rely wont is gauss meter and decent oscilloscope,but in my country price off the instruments is to high for my pocket . Without of precise instruments oll off my experiments is not good enough.

[Jetijs]

Yes, a gauss meter would be very handy, but those things cost a fortune

Anyway, I did some experiments today. First of all I replaced the neo magnets on the static device with ceramic magnets. And yes, now I need only 8V at 70mA to switch the flux using the same many turn coils. So the problem was indeed the core saturation.

Also I tried to recover the inductive spike from the coils. I used some 5w light bulbs as a load. They light up, but the brightness is dependent on the input voltage. The sad thing is that when I attach the recovery part, the motor RPM's start to decrease and the current consumption goes up. I tried that with various timings and duty cycles. Always the same. I will try this again using weaker magnets, maybe the core over saturation has to something to do with that. I used a recovery part similar to Bedini SSG, something like this:


If I had another winding on those cores I could try out the recovery system that puts those inductive spikes back to input capacitor, but I am not sure that would work either. I will try all kind of timing/duty cycle configs with these 1" cube magnets and then I will replace them with smaller ones and do these tests again and see what is the difference.
Thanks,
Jetijs

[zhorv324]

Jetijs ,I did not want to talk earlier about recovery (before you have done test). Now you see what I have written about parallel path static device (meg) its same behavior in motor. You cannot use recovery in standard way(with diode only) because motor become (in part time) transformer and motor characteristic go down I mean RPM and TOURQE. As you see motor current rise and if you carefully measure you will see that current you recovery is identical with current rise on motor side its typical transformer behavior (+ loses).Now I tell you what I think is happen in motor. Motor use part off BMF, and that is one off the reason why motor consumption remain almost same. But this is only mine opinion and I cannot explain that in standard way . I look forward to see your another test on motor , and I will have same new suggestions when times comes. And yes I'm still tray

[Jetijs]

Well, maybe.
I just know that in my attraction motors where there are no magnets at all, but the construction is similar, the recovery works great. Peter said that you can not recover much if there is a magnetic field interacting with electromagnetic field, but it works great if there is only electromagnetic field. I guess that is why I could not recover any energy to the fron side cap when I tried it on a Bedini style fan mod.
Anyway, I will take some scope shots tomorrow, then we will see
Thanks,
Jetijs

[zhorv324]

Well good luck with experiment and I really want to see oscilloscope shots because my oscilloscope die last year and I still collecting money for new one.
