Hi synchro1.
Yes, my 'GAP Power' motor is half-baked   The driving coils are bifilar so I could do push-pull.

But recently I've been focused on solid-state MEG/figuera/partnered output coils thingy, will see how that goes soon.
2 blue wire coils N and S with magnets N/N S/S and 2 identical partnered output coils (mirror image).

Sorry i didnt make that very clear-my mistake.
2 rotor segments at each brush-50% of the time there is 3 segments per brush in contact with each brush-so 4 segments at 100% and 6@ 50% time on all up.

I thought you were filing the brushes to a point so that only one rotor segment one each side would be connected at a time.

@Poynt99

As opposed to 4 rotor segments?

Yes, when any two commutator segments are in contact with one brush then one rotor coil is effectively shorted through the brush to prevent arcing. If the brush is tipped or narrowed then the time at this point is drastically reduced hence the transient effects noted in the scope shots.


However it gets even more interesting when the brush timing is altered and the stator coils disconnected. Realistically the universal motor becomes a switched reluctance motor whereby the rotor field it attracted to the stator core. To be more precise the rotor field is attracted to the area of the stator core with the most ferromagnetic material hence the term reluctance.


It should also be noted that since the stator coils are no longer in series with the rotor coils they are no longer bound to the same applied current. If the rotor current changes in some way then it's magnetic field changes as well and this field change translates to the stator coils not unlike a transformer. Now it gets a little tricky because in practice we have a transformer with one coil moving relative to the other thus we must consider the field change in the rotor as well as the change due to the fact the rotor field is moving.


I think I know what tinman is doing and it relates to the Alexander Dyna-motor found here---http://www.rexresearch.com/alxandr/alexandr.htm as well as the Robert Adams motor/generator.


On a note of interest Lenz law is completely dependent on one magnetic field opposing the field change of another magnetic field which we call "induction" which is actually self-induction however Lenz Law has no application if one magnetic field ceases to exist because this is not "induction" by definition it is something else.

Dear All.

Short and sweet.

Possibly pertinent ?  http://www.climtechsolutions.com/wp-content/uploads/library/Lindemann/ElectricMotorSecrets2-Lindemann.pdf

And finally, Brad, did you or did you not, employ the use of N52 strength PM's in your Rotary Transformer ?

Cheers Grum.

Grumage,

In your second video, what exactly are you shorting the brush too?  Were you shorting the brush holder brass to the motor frame or were you actually touching the brush carbon itself?

I ask because normally the motor frame is not electrically connected to the stator or rotor.  If you were shorting the brush holder metal parts to the frame, then there would only be capacitive coupling of the brush voltage to the stator or rotor windings (assuming you have no rotor or stator winding connections to the motor frame, intentional or otherwise).  If you were touching the carbon itself, is it possible you were more so changing the manner in which the brush was contacting the rotor (i.e., tipping the brush slightly, changing tension, etc)?  Either way the results are interesting.

As for the N52 question you posed, have you received an answer?  Did you use an N52 in any of your replication attempts and if so, how did you utilize them?

Dear picowatt.

I was in fact using a "Pozidrive" "cross head" type screwdriver gently touching the leading ( motor rotation ) Commutator segment to the brush holder. In fact you can retard the speed by placing the screwdriver on the lagging side. This was done with the shaved brushes and later with the standard brushes. In fact I actually state verbally what I'm doing at 3.38 minutes into the video.

Now as to the use of permanent magnets? The " jury is still out " !! Brad seems to be ignoring MY questions, perhaps you should ask him ? However if the drawings posted on page one of this thread are anything to go by, my gut feeling is that there ARE PM's involved, somewhere. 

Cheers Grum.
