Holcomb Energy Systems:Breakthrough technology to the world

[Jimboot]

Good evening.
Some work this weekend.
Not sure where this will take me, but even though my wife is mad because I didn't go anywhere, I had some fun.


The first video shows the pulses in low frequency and the second in "high" frequency.
No output coils yet.

Nice work mate. My wife is also mad

Looking through the DNV report and photos of the demonstration setup for the so called DC switched system, I note the three static inverters in the same rack.
The DNV report does not give precise details of the system that was tested.  I suggest that in this later iteration (see attached png), the rotor is driven by the three static inverter outputs. The model of inverter used has DC inputs so a battery storage system could be used.

I would also suggest the rotor in this system is conventionally wound as a three phase motor i.e travelling MMF and is not a 16 salient pole type.

Holcombs wife says in one of  the video's that her husband applies for a patent when he has an idea before he builds it. This approach is likely to have a lot of fails don't you think?
 
The DC switched system as described in his single U.S. patent (and WIPO patent applications), will have huge IR losses, whereas use of a three static inverters to produce three phase AC, will at least have some efficiency when energising a conventional motor wound rotor, (see figure 48 in WIPO WO2021063522A1)


Also the statement out of the company refering to all their current systems are using AC, supports this idea... From this I would extrapolate that he patented the idea of a DC switched i.e. sequenced 16 salient pole system, then when he built it, discovered it did not yield the results he hoped for, compared with the AC system.


One other point I would make, is that a DC switched, sequenced 16 salient pole rotor resultant stator phase sine, is distorted and full of harmonics, less so if you just rotate 3 ON salient poles but nowhere as clean as the AC sine rotor system.

This video a bit better.
It is better to put a CRT in a stator only its screen, where there is no metal inside the CRT.
One note, in the middle of the CRT shows much less field than near the stator iron.

p.s. corrected

I'd like to view it, but it says it is private and does not play. Can you fix that?
Thanks,
bi

{edit} thanks for the fix. Really cool. Good job.
