If you don't pay attention to this, you will never get to the required conditions.

Are loaded pickup coils included in simulation? Or only interactions between rotor and stator magnets with ferrite as middle man.

Yes, including the rectifyer circuit, buffer capacitor and load resistor.
For those who are not aware of the capabilities of Ansys Maxwell: a complete setup, including electronic circuits, can be simulated in 3D.
Maxwell is capable of presenting a lot of parameters:
- torque and force
- all electrical parameters
- Magnetic field strengths (H and B) and vectors
- local energy generation/consumption

I didn't post too much of simulated results here, because it seems to have not much interest.
I could start a separate simulation thread if sufficient interest is present.

Hi Rod,

Very good news, congratulations and now a series of fine tunings may start to bring the other gen coils into similar condition and then to sum them up into a common output.
Have you used drive signal chopping?  What is the input current now?  Shape of the output waveform?

Thanks,  Gyula

It works. 
I was right about my early observations. At last we are moving in the right direction.
I was able to draw 32 m amps from one coil with out any load on the motor.   There was no change in RPM or drive coil load.

Now we start work  ?

just a small point the RPM needs to be right. full speed is not always the correct speed.

I have screen shots to post of the wave forms.

Could you please upload sim file(s) somewhere?

Tweaking ready simulation is 100x easier than doing from scratch... Lately there's been so much new data hard to keep up.

As long as you are searching for an unknown effect simulations are NOT the way to go. Simulations have hardcoded, limited rules how they are supposed to function, they cannot predict unpredictable.
