Hi again.

Yes you could connect one segment to the armature shaft and then connect to the frame to pick up the changing power.  However that power would have to pass through the bearings on the armature shaft to get to the frame.  There are a few machines in industry that do that but they have a special conductive grease in the bearings.  Otherwise there will be some arcing and burning of the bearings which will shorten the life of the motor.  We could connect the commutator segment to the shaft and then just let a brush ride on the shaft without the slip ring.  That would eliminate the problem with the bearings.

Take care,

Hi @citfta,

I believe if you have full metal rolling or ball bearings, the conductivity should be solid.
Must typical bearings (cheap, Chinese) have all sleeves and bearings tracks (where balls roll)out of steel or an alloy which conducts.
Also the laminated steel core from armature is fully pressed bare into shaft.
So, drilling a small hole on inner armature lamination and adding a small metal screw will do to run it to comm. segment.
Lastly, you do not need a full brush-spring-casing...
Only a hard metal strip (like they use for spiral coil springs) and have it ride on shaft.(if bearings alone do not work, but, please try bearings alone and you will be surprised)

Take care

UFO-

I believe you are right.  The armature (resistor) should be able to double as the motor itself simply by adding field magnets.  We will have to see how the back-emf alters the system, but a very good idea and should absolutely be tried. 

Thks Floodrod, I think so

This is just a theory- but it is very possible that the universal motor's back-emf may self-regulate the resistor's impedance - thus acting as a resistive tuning mechanism, locking in the balance.

I think your theory is right, on all these motors the armature windings are a series loop, but closed, so at the last coil wound on armature, the ending terminal attach to the starting first coil, and here it is a different design than Figuera's that the series resistors or coils are open at both ends.
On these type of motors the EMF serves as a kind of balancing controller and unless we do not add major mechanical torque to shaft, the amps are completely stable and regulated by EMF.

This may make the system much easier to build for anyone, as all they need is a DC motor - and slight mods yield an entire commutator / resistor system with no need for a separate motor.

Excellent idea.. 

I think so as well.

I whipped together the wiper motor config identical to Cifta's demo  and also use a visual aid to explain the differences of the driving currents, as compared to the common Figuera wave.

I realize what we are explaining may be confusing to some readers because the current path is a little tricky to see right away.  But maybe this video and view of the waves will not only make it clearer, but also perhaps reveal how this "flipped" scenario can be used for benefit. And explore what it can lead to.
