Holcomb Energy Systems:Breakthrough technology to the world

[SolarLab]

 Rakarskiy - Looks like you GOT IT figured. Congratulations, excellent work! Thanks
for sharing...

Listener192 - the tech brief and some related discussion might have been near the
beginning of the OUR Holcomb thread but not exactly sure where or when. Sorry.

Dog-One - Pure Iron and other metals with excellent B-H characteristics are available
but can be quite expensive especially in small quantities. Fabrication to your device
specifications is costly as well and machining it leads to a lot of waste.

Another option is lamination construction. There are a few firms that will do laser
cutting and stacking so the stamping fixture fabrication is eliminated but the process
is rather limited in configuration. Holcomb did this himself - there's a picture I posted
of his lamination setup.

You'll have to put on your "thinking cap" for this part since it appears to be the hard bit!

  - The option we're working on at the moment involves Soft Magnetic Compounds (SMC)
which are initially various powder mixtures that are compacted into a mold under high
pressure (800 MPa) and sintered in an oven. This process is ideal since the shapes
do not limit the overall design and optimum permativities and B-H curves can be achieved.

Since this overall concept is geared towards an educational aspect, the added SMC part
of the course lab adds a significant amount of additional knowledge in a variety of areas.

Building (machining) the molds and compacting at 800 MPa and Sintering is a challenge
but the flexability and cost savings more than makes up for it. Having a CNC Mill, a 60 Ton
Press and a Sintering Oven also helps.

There are SMC companies that have test jigs you can
purchase and evaluate various SMC materials as well as a few that sell SMC material as
"slabs." Expensive but for a proof-of-concept it's a reasonable option.
   
A good scrap metal yard or supplier in an industrial area is also another source but you'll
need a Tesla Meter and Coil (as mentioned in a "Saturday Fun With the Kids" post.

Board is acting funky as usual so posting is a real pane in the ass - bold sticks, formatting
is useless - in general just a lot of time wasted... so screw (F___) it...

Hello Dog-One,
You ask:

Do you see a method where we can purchase off-the-shelf core materials to fabricate either a rotary or linear system for bench testing?

I said this back when the Holcomb system was first described. Sounds like a 3-phase slip ring induction motor with a locked rotor. And it still does. These are available in standard industrial NEMA packages at reasonable cost. Although not as popular and common as the squirrel cage, still could be found on the used/rebuilt market in like a 4 or 6 pole integral kW, 230/460V version. Just use a shaft coupling, collar and torque arm bolted to end frame. Put the 3-phase mains to the stator, thru a Variac preferably and you have the rotor (stationary) windings available via slip rings.

The rotor winding is typically connected to a resistor bank and used for speed control in the standard applications. The technology predates modern inverter control. And locked rotor testing is a text book method to characterize machine parameters. No doubt been done thousands of times by engineers and technicians. Never heard of anomalous energy appearing. I don't understand how Holcomb does it, so I doubt it happens. But the method I just described gives you a starting point with available hardware. From there, you could alter the windings on the rotor and figure it out.

Love to see it happen.

Hi Bistander,

Are you experimenting with this approach, or planning to develop the concept, using a 3-phase slip ring induction motor?

Just asking since there are a few questions I have regarding the theoretical operation.

Regards,

SL

Hi SL,
Unfortunately, presently I'm in no position to experiment like that. Surgery scheduled for tomorrow. I have, and will, consider it, but personal policy is not to build things that don't work. That does not stop me from experimenting. But truthfully, with Holcomb's scheme, I have yet to understand objectives of such experiments. I find your investigation and analysis very interesting but can't follow the process thoroughly. I hoped you would do a physical model.

I plan to be around so will participate where I can.

Why did the Holcomb create a system for switching magnets that have an imitation of rotation? The answer is so simple as to change the magnetic field in the zone of the generator phase for the entire amplitude of the hysteresis. No simulator takes into account the inertia of the magnetic field of the core. Spaces in a magnetic chain, for the same purpose. It is difficult to break the magnetic flux, which is associated with the ring, in the generator the flow rotates, crossing the phase wires, using mechanical force when rotating the rotor. In a static core, to do it just to control the polarity of the coil. Holcomb went in the most predictable way, it pulls the field in the iron gland, switching magnets, while the stator field does not weaken.
Sincerely.
