Flunn paralell path!!!

[Ted Ewert]

Great idea Ted !
I think we are very close to understand devices like Steven Mark TPU and Sweet VTA.

Thanks.
I think this is close to what the Magnacoaster is all about based on what little info is available. There are a lot of variations on this type of theme that can be used to generate energy.
Leveraging flux is certainly more efficient than brute-forcing it like we do in most of our motors and alternators.
I think I'm going to start another thread on this concept.

PPMM ver.3

Just testing after making it all in one piece:

YouTube - SRSM3

I intend to post more ... later.

Nice motor and construction, can you give the construction details?

[sciencisto]

construction detail

I have another website where I am keeping all the photos and films that I am doing when experimenting with something.
As for PPMM it is here:
Index of /laboratorio/esploroj/rownolegle_strumienie
SRSM1 is for the 1st version, and so on.

Presently I am testing version 2 and 3.
On the first page of my hand written lab notes (file http://servilo.website.pl/laboratori...M2/srsm2_1.gif ) you can see the schematic of the driving circuit.

Don't hesitate to ask me if something is not clear.

motor and generator

I've performed a few dozens of tests with this machine where the windings were setup in different way. What was interesting in these tests were the stator coils connections.
First I connected only 3 stator coils to the powering circuit and the other 3 coils I used as an alternator. So in one case I had a motor and an alternator.
On this video you can see another connection, coils 1-4 are the motor and coils 2-3-5-6 are the alternator.

Brillant sciencisto!!!

I knew that somebody would come with a way of implements with theses
motors....

Many,many thanks!!!

next test

I just uploaded a short video of another tests, in which the parallel path magnet motor SRSM3 is shaft coupled with 1 kW old military soviet DC generator.
YouTube - SRSM3 -- DC generator .

[Jetijs]

sciencisto,
thanks for all your work Can you elaborate more about your motor design? Is it a 6-pole? I think that DC generator is a bit overkill, maybe if you have something smaller, you could try that. Also as far as I have observed these motors become more efficient at higher input voltages. I have built a 2 pole motor and had it tested in a local physics institute, unfortunately the efficiency was about 40% at best. The test was done using a small DC generator with known efficiency. Maybe you can test the torque using the prony brake test? Very easy to do and good precision. Here is my motor:


What is the air gap between your stator and rotor?

[UncleFester]

Neos too strong?

Maybe the Neo's are creating too high of a field. Flynn used Ceramics I believe. Any thoughts Jeti?

Hi Tad,
neos deliver high torque, if I set my motor up with ceramic magnets, it might get more efficient, but the torque wouldn't be great and there wouldn't be the promised high torque to weight ratio anymore. Italian builders have done a great job in replicating this type of motor, they all use neos. Neos are fine as long as you don't oversaturate the core, otherwise you will just waste excess power. The general rule of thumb is to get the core flux path square area 1,5-2x bigger than the pole surface area of the magnets. This is as far as I know

Hi Jeti,

Ah yeah. I was concerned about losing torque by using ceramics. I guess the only way to overcome the loss of torque would be to keep stacking rotors. The Italians did an awesome job! Love their work!

The other issue that boggles me is what was Flynn doing when he built the 10KW unit? It seems smaller than all of these other tests yet produces 10X the power if what Flynn say's is true. That unit is only 6 inch diameter and like 10 inches long?

I am willing to bet money on the fact that it would be more efficient to have many thousands of ampere turns using 30-40 gauge wire and higher voltages. Just like I am doing on my Gray motor tests. (maybe adding capacitor discharge in that scenario as well).

Can you elaborate more about your motor design?

Look here:
Index of /laboratorio/esploroj/rownolegle_strumienie
this is my folder bout parallel path. It contains 3 folders, every motor has it's own folder. The one I mentioned in my previous post is SRSM3, but in folder SRSM2 you can see all the construction details and a few videos of some of the tests I did.
The electrical schematic of the powering circuit is here:
http://servilo.website.pl/laboratori...M2/srsm2_1.gif

Can you elaborate more about your motor design?Is it a 6-pole?

Yes, all three motors are 6 pole. I would like to test also the 2 pole version -- would you lend me your motor to test it by me?

I think that DC generator is a bit overkill

Indeed it is quite heavy machine to turn, made for gas motors, but anyway I wanted to try.

Can you elaborate more about your motor design?maybe if you have something smaller, you could try that.

I do have, next tests will be with other machines, a CD magnet motor, a car alternator, a DC motor, a 3 phase motor.

Also as far as I have observed these motors become more efficient at higher input voltages.

Well, drawing conclusion from my tests I see it is not always like that. It depends on some factors like the sensor position, how the motor coils are connected, how much impedance they have, how much is the load etc.

I have built a 2 pole motor and had it tested in a local physics institute, unfortunately the efficiency was about 40% at best.

I was following your experiment posted here -- very interesting for me, thanks and please, don't give up.
I also feel that they didn't really know how to use your motor so they didn't achieve the max efficiency your motor can give. I think it is at least 67% efficient. One just need more patience in orer to set right running parameters, to tune it.
Tuning PPMM my take some patience and time, but it's worth to try.

Can you elaborate more about your motor design?What is the air gap between your stator and rotor?

I don't know exactly, it looks like 0.5 to 1 mm.

[sciencisto]

Maybe the Neo's are creating too high of a field.

I am almost sure in my motor SRSM2 and SRSM2 they neos are much to strong and the core is oversaturated. I am going to change the for weaker ones.

In case of Jetis' motor I think they magnets are just right or if oversaturated core, it is much less compared to my motor.

[sciencisto]

confirm observation

The general rule of thumb is to get the core flux path square area 1,5-2x bigger than the pole surface area of the magnets.

That would confirm my observation. The version SRSM1 I was testing first, was build like that (you can see it on the photos, folder SRSM1). It was running on 10V x 0.1A = 1 W and I could not stop the shaft with my hands even when they had leather gloves on -- very strong.
