@robbie47,

No. I only use the fan rotor. I have removed ALL coils and pcb inside the fan. Then I cut the
four legs to the fan housing. I cut off all the fan blades and use a little sand paper to get
rid of the fans remains. I take out the circular rubber magnet inside the hub but leave the
iron ring because it is difficult to remove the iron ring without damaging the hub. Then I glue
two magnets on the outside of the hub. Now I have a two ball bearing rotor that spins
very freely. The only coils is the one you see glued to the plastic box. The fan was a 80mmx80mm
computer fan.

Edit-1 Added a scope shot of the oscillator. (Use hand held camera so quality is not very good.)

@groundloop,
Thanks again for the details of the rotor.
So, basically the rotor is not moving in your present setup?
What is the position of the neo's towards the coils you use? Are they facing the coils or 90 degrees rotated from the coil entries?

@robbie47,

No the rotor is stopped by hand. The rotor align itself North / South because of the low friction in the bearings.
The oscillation starts by itself when I flip the rotor a couple of times. This to trigger the L1 coil. Then I stop the rotor.
Then I adjust the variable resistor to highest value without the oscillator stopping to run. The oscillator will run when
adjusted so 10K is in series with the base of the transistor. I maybe fit an extra resistor later on.

The battery voltage is now: 10,34

I will run this circuit through the night to see what the voltage is in approx. 8 hours from now.

@groundloop,
The oscilloscoop pictures helps a lot understanding the circuit.
It seems you measured it with the probe AC coupled?

[Groundloop]

@robbie47,

Yes, AC.
