Why bother with any motor unless it has the potential for over unity?? I can go buy a motor off the shelf with 90% plus efficiency, so what's the attraction?
If they're used in a motor properly, magnets can provide enormous amounts of extra power. This is no idle wish either. Switched flux works slowly, and has to be used that way. It's just going to take a little more research to figure out an efficient drive configuration.

Here is why you want to use Flynn's motors:

"QM Power motors, generators and actuators offer the highest commercially available peak and average efficiencies of any electromechanical device.
A common misperception is that motors "are already 80-90% efficient so there might not be that much technological improvement needed".  However, as shown below, this marketed “peak” efficiency is only achieved at speeds where most motors are seldom actually operated   In fact, for most “variable” speed applications (electric vehicles, power tools etc), the highest “peak” efficiency is actually below 60%.  Since these applications are also variable, the actual “average” efficiency is often less than 30%.
Most PPMT motors have peak efficiencies in excess of 90%. In addition, even if normalized down to the same peak efficiency as an existing/conventional system, the average efficiency of a PPMT variable speed and/or load application is still often 1.75 or times or more as efficient as conventional alternatives.  Average efficiency is directly proportional to battery life.
Since PPMT's peak efficiency is available near its peak power, it also eliminates the requirement for motors to be oversized to achieve high efficiencies in fixed speed applications substantially reducing cost ."

Furthermore there are things which are not said by the experimentators. For example, my previous model (photos and films here, not yet in youtube: http://servilo.website.pl/laboratorio/esploroj/rownolegle_strumienie/SRSM1/) was really strong. With 10V 0.1A input (=1W) running without any load, I was not able to stop it by holding the shaft with leather gloves. The input current went to max 2.5A (=25W) and the motor slowed down a lot, but no way I couldn't stop it. To compare it with other motors, I could easily stop a 75 W 3 phase motor when holding the shaft with the same hand.

I did a dozen of tests with motor-alternator windings connection of SRSM3.

Winding 1-3-5 were powering the motor and winding 2-4-6 (the same motor, the same stator) were working as an alternator. The film below shows another setup, windings 1,4 are powering the motor and windings 2,4,5,6 are used as an alternator so that power is drawn out of them.

Maximum efficiency I could attain was 64% so quite law. But it's
just a beginning of this tests and I believe more will be seen.
Still the question is, how much power is now on the shaft?

I just uploaded a short film from these tests, here:

Very interesting setup you made.
The motor being alternator as well, kind of having a compact motor/generator machine.

As you mention, you only get 64% efficiency, very close to the 65% you got from a separate alternator.
Somehow I strongly feel you have maxed out the performance from your design and it is approx 81%.
When two equal or similar units are used in series the efficiency is divided across both units.
New setup: 0.8 x 0.8 = 0.64 = 64%
Old setup: 0.81 x 0.81 = 0.656 = 65.6%

Adding an external alternator to the shaft (besides the internal load) will only slow down the motor even
more and any alternator output will be seen as less output from the internal windings.
The outputs will simply balance each other depending on which load is the greatest.

I have one important question for you, if you don't mind.
If you let your motor Free Run without load at 30V and 1.1 amp No-Load current....
How hot will the motor become after some time has passed, let's say 1-2 hours?

You see, the 30V x 1.1A input at No-Load = 33W lost and this will heat the motor.
The main problem of the losses is the hysteresis and eddy currents of transformers steel.
When the steel passes a magnetic field it tend to brake a bit due to these losses.
This braking is comparable to you braking the shaft by a load and see an increase of input.
Remove the internal dullness of SiFe steel and suddenly you have greatly increased efficiency.

------------------------------------------------------------------------------------
Please read this:
I have tested toroidal powder cores vs toroidal silicon transformer steel inside a circular magnetic field.
The setup was a 30V DC motor with extremely low no-load input, that turned a shaft with the toroid's
inside the alternating magnetic field of sourrounding magnets.
The motor No-Load current at 30V and 3000RPM, without the magnets in place, was approx 7mA.
With the silicon steel toroid placed inside the fields, the No-Load increased to 100mA.
When a powder core was used the No-Load input increased only 1-3mA, depending on the type used.

Conclusion:
SiFe Steel = 100mA increase due to eddy currents and large hystersis.
Any good powder core = maximum 3mA increase. (Good cores are MPP, SMSS, Kool-Mu, Hi-Flux)
The worst powder core was a regular cheap iron powder toroid. It increased input to approx 30mA.

Powder core motors is being in the focus right now by several large manufacturers.
When used together with heavy duty Litz winding the efficiencies can reach 97-98% over a wide RPM range.

That is what happened when I load the shaft with an alternator, but I didn't make power out measurements in that time.

If you let your motor Free Run without load at 30V and 1.1 amp No-Load current....
How hot will the motor become after some time has passed, let's say 1-2 hours?
I never let it run for so long, but it would be interesting to do that. Now it is shaft coupled to an old Russian DC generator, but later, between experiments, I am going to try, let it run for an hour without any load.

You see, the 30V x 1.1A input at No-Load = 33W lost and this will heat the motor.
The main problem of the losses is the hysteresis and eddy currents of transformers steel.
I also feel there timing, which is now duty 50/50% is too long. I want to build a circuit that can vary the time on and off, so a PWM, duty or pulse with regulation. Any suggestion about such circuit?

Any good powder core = maximum 3mA increase. (Good cores are MPP, SMSS, Kool-Mu, Hi-Flux)
I really want to have other cores, the best ones, but where to take them from?

This place.....
http://www.cwsbytemark.com/index.php?main_page=index&cPath=206

The cores lined up, from best to worst. Never use less permeability than 125u. Higher is better.
MPP, Sendust, Hi-Flux, Iron Powder, Mega Flux (the last has to low permeability to fit a motor)
Forget any ferrite core. They can't be machined into desired shape and they don't handle high flux.

Just for your curiosity!
Here's a guy that built a small powder core slotless outrunner with extrem efficiency for its size.
http://www.powercroco.de/slotless_outrunner.html
Please use google translate if needed.

Here's a forum discussion on this particular motor.

Thanks, FatChance!!!.

I have told my friend, who build the motors, about the materials and he is willing to build another motor using much better core, maybe one of these you mentioned. I wonder how they are called in Polish and if they are available here in Poland.

The motor is really amazing. I am reading the translation.

Interesting test, and well done. Thank you for making all the measurements clear and easy to read, (and for the use of subtitles).
You mentioned that the generator had it's highest efficiency at 3k rpm. During the 39 volt test, the system showed a 30% overall efficiency under load. When you dropped the voltage down to 29 volts, the RPMs decreased further and the generator presumably became even less efficient. Yet the overall efficiency went up to 36% into the same load. How would you account for this?

I probably was not clear, I wanted to say that this machine is a 3000 rpm DC generator build, but I don't know at what rpm it has the highest efficiency. I guess it is 3000, as it was build for, but I never run it so fast, so I don't know.

Yet the overall efficiency went up to 36% into the same load. How would you account for this?
As far as my experience with this and other motors and generators, this kind of changing efficiency with decreased speed is nothing extraordinary. In this particular case I explain that at the higher voltage the motor was supplied too much power for the load. If I increased the load the efficiency would grow. The motor core is more oversaturated at higher voltage.

BTW, the highest overall efficiency of this setup I succeeded to measure was 56%
