Holcomb Energy Systems:Breakthrough technology to the world

Sorta. But what you show is an armature, not a field winding. The field on that motor is PM, and a lot more than 2 or 4 poles. What you see in the photo are teeth and slots, not poles. The magnets determine the number of poles. If you were to wire those coils like they did for a 2-pole application, you'd have the same issue.... only 2 effective coils and a lot of wasted copper.

Yeah, sorry, my bad, confused poles, meant teeth...


But point here is that a number of coils wound on each teeth, next to each others, determine a Pole, and that arrangement could be modified through their electronic switching PLC (programmed) and executed by each channel in many different "fashions".


I do not know if you've noticed, but on Holcomb's Patent Diagrams, he shows different configurations of magnetic poles (N-S) arrangements...


See image 23 of a different setup below. note the polarities change versus the FIG22 (which you upload it before)....yes, I know it has a different inner rotor coils added...but referring to same rotor as seen on Image 22 Poles config.

So, what you are saying is basically what Cotnoir did...in his own way of winding and switching...He used 6 Poles in his outer static rotor.


Now, in the other scenario, (lap winding) when we apply power to coils in series, with a "T" derivation to commutator element, and apply power at just two or four points of armature coils...current will remain the same within the whole series of coils, typically lower, no matter if we apply more power (V) to Armature...that is what happens in any lap wound motor...as I will dare to say that it even lowers amps, as we increase V...correct?

Sorry Ufo,
I don't know what the other fellow did. And you lost me. What I am talking about it the common universally available polyphase machine like the NEMA standard 3-phase induction motors or standard synchronous generators of which millions are working in industry today.

Ufo,
It depends. Here, they appear to wind a core which appears to be from a DC armature to use as a field. Used as an armature, the field would determine the number of poles. Typically the coil span on the armature is made to be very close to the pole pitch, so one coil side is under a N while the other coil side is under a S. The point here is that it is a waste of copper to have conductors (coil sides) in the same slot carrying current in opposite directions. Current one way simply cancels opposing current. The net current in the slot contributes to the work.

And I had not seen Fig. 23. Obviously a 4-pole attempt. Has same issue as the 2-pole Fig.22. This has 2 coils on each tooth, in parallel of the same magnetic polarity, seemingly separated by some sort of magnetic bridge to adjacent teeth. Pardon me, but seeing what I have of this guy, I'm not likely to read the patent to further understand his logic, or lack thereof.

Hi All,

I have found in the past doing Back EMF this simple diode set up works very good. It also protects mosfets at high speed switching.

Output should have capacitors to collect return voltage of BEMF.

Hi Ufopolilitics...
"We all had this scenario in front of our eyes for hundred of years... "


in my only  post some time ago I was also asking something that looks very close.
anyway, a lot in common with Figuera and Antonio D Angelo patent.
Just rewinded a old rotor as holcomb/D Angelo have...need sometestings
