What is so special about the motor that needs to be powered both from AC and DC power supply?

What is so special about the motor that needs to be powered both from AC and DC power supply?

To not overcome ,in average,the rated output (differing rated from maximal) because EE-machines https://de.wikipedia.org/wiki/Resonanzkatastrophe

An AC generator with a fixed rotor Flux would cut the stator coil wires,  as the rotor comes into registration with the respective stator coil, so the stator coil wires would see a flux change effectively.


In the Holcome and DZ generator only flux linkage couples the coils as there is no physical flux movement (flux cutting).


In the DZ generator moving fixed amplitude poles across the rotor produces very poor induction in the rotor coil. I found that the rotating poles needed their flux modulated in a sinosoidal fashion as they crossed the rotor to obtain reasonable induction. However energy is wasted when the stator coils are energised out of registration with the rotor. Also relatively low turns for each stator coil is required to minimise inductance, allowing the current rise in the coil to occur within the switch period. Holding these low inductance coils on for several switch periods is wasteful in terms of I/R losses. Modulating the coils so the current was always changing in each coil did mitigate this while improving induction.

I built the DZ and you can see my findings reported in the Pierre Cotnoir threads along with images. I tried many configurations including relays and solid state and two  different sized rotors and stators


The DZ is not the same as the holcombe device apart from the concept of moving poles around a stator. DC energization of coils and possible saturation of steel is going to result in I/R losses in the form of


heat. You can see they have a fan on the top of the holcombe device this is indicative of this. Why they say in the video "no heat is generated" I do not know?

Hello to All,


I read the whole DZ Generator Cotnoir Thread (94 pages)...and it was a big disappointment to see the end results, basically starting when Pierre decided to go away taking all his videos off the net, before any of you got to know every detail about his setup.


At the same time it was great to see such incredible builds, a lot of work there!!


@L192: Your build was very impressive, a lot of time and money spent!!...but basically very well put together...And I feel your frustration and disappointment not being able to achieve the expected results...


In my very honest opinion, and with all due respect to all that replicated there...the development process to Replicate DZ Generator was not handled properly from Page#1...not your fault at all.


1- The very first thing that was supposed to be done in Pierre Cotnoir Thread, since Page 1, like in any setup development is always a "Normal Procedure"...is to make a Main Diagram of ALL MAIN COMPONENTS PARTS AND CONNECTIONS.


1a- From the main Diagram, then it should have been reduced to a simple BLOCK DIAGRAM, to simplify the whole setup into Subsystems, which gives easier access to point something out on further discussions.


This very important part I never saw it there (maybe I missed it, but I don't think so, correct me if I am wrong)...as it serves as a Guide to refer all new incomer builders to go first to those TWO MAIN DIAGRAMS.


2- Is a consequence of not having #1 above...and that is to start randomly picking up where to concentrate first in your builds...as I noticed so many people concentrating first, in how to write the codes for the Arduino setup...or what type of Relays were used...or what diodes, or what Board # for the processor (Arduino), and a long etcetera, etcetera...
And of course...it concludes as disregarding some of the main Components, or leaving it for the end...


For example, no one ever asked, why Pierre used that Old Type and modified Bulky Transformer to charge and supply power to the switching coils as to charge the Supercaps?

Pierre could have used instead of that Bulky Transformer, a nice, newer, cheaper, less consuming...switching PWM Digital Display PSU...I mean, a 30V 10 Amps is so cheap in online shopping!!


Did you guys ever ask that question?...why an old transformer?




I noticed many replications did not include that Transformer.




But, forgetting about the Transformer...what about a Diagram for the way that Coils were WOUND?


Yes, I saw many Diagrams there about winding and setting coils...but they were all by replicators, "assuming or guessing" what Pierre meant...


Pierre only shows one or two videos with his UNFINISHED coils diagram, but trying to find a way how to solve some issues...so it is NOT a Final Update on his windings circuit...




IMHO, the MAIN COMPONENT in Pierre setup is his Switching Static Rotor, then the Transformer use.


I would say that his Inner Secondary design, was not very efficient...since it was only one coil, with a huge piece of steel, but this design does not allows for greater collection of Induced EMF of the whole 360º Rotary Fields...However, Pierre stills loops the system.




Anyways...I again, thank you for all your efforts in trying to replicate his design, and could say your setup is much better built than the original.

I did not post everything that I tried but certainly a transformer was used for one trial providing halfwave rectified DC to the switches, to provide an amplitude changing stator flux. I had my system synchronised to the line zero cross point to start my switching sequence. 

@ufopolitics


No frustration really, as I have spent many hundreds of hours previously, replicating patents for various devices, unsuccessfully.


I believe the DZ was a hoax, as when his original burnt out, why would he not just replicate what he knew to be working, instead of starting a whole new design (unsuccessful). The replication attempt was not wasted as it illustrated the problems  encountered with the concept generally.
