@all who observe a speeding up of the rotor when putting a load to a pick up coil or when placing the pickup coil in opposition to the drive coil:

In case you have only one drive coil, the bearings are put under stress, because the rotor is strongly pulled to one side.

If one places a loaded pick up coil in opposition to the drive coil or in other cases somewhere else near the rotor, the stress on the bearings is a bit less (less one sided) and hence the increase of speed.

I observed with my contraption (posted further up in this thread) that it is important to have a "balanced stress" on the rotor/bearings, which can be achieved with a pair-wise arrangement of drive coils and pick up coils (as in Romero's motor-generator). The rotor should not be pulled to one specific side if one wants the bearings to run freely.

I will change my rig accordingly, using a pair of drive coils and a pair of trigger coils. Trigger coils can be further away from the magnets than pick up coils, because the trigger signal does not have to be strong (therefore a pair of trigger coils causes only a small drag in comparison to a pair of loaded pick up coils).

During recent tests I was pondering the possibility of using two paired sets of drive coils all wired in series configuration to be driven from the one pick up sensor.
As seen in the picture below, drive coils pair 1 is magnetically aligned to attract the magnets on the rotor disk. Drive coils pair 2 is magnetically aligned to repel the magnets on the rotor disk. This meant drive coils 1 and 2 would be wired in series to double overall inductance and coil resistance, consequently halving their power consumption. In turn this would give us the opportunity to create a repelling and attracting force simultaneously to the rotor disk.
The only technical issue with this configuration was working out the phase of the two coil pairs, so that when they engaged they did not electrically oppose each other in circuit.
This is where it got interesting…I experimented with the coils in phase with each other and out of phase with each other. When the two drive coil pairs generated a charge induced by the magnets and the polarity of the charge was in opposition to itself, drive current dropped to 25 m Amps. Motor RPM was 1250. When I reversed the phase of the two coils motor RPM increased to 2200, drive current escalated to 180 m Amps.
I found this to be a very interesting result and something that needs more work. I am posting this result as help.

Thank you!

Am I understanding this correctly the voltage induced by the magnets caused the coils to short.

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. 

Same with my experiments. Exactly 30 ma and not change on RPM.

Fausto.
