Serious HES derivative project proposal

[SolarLab]

Hi Fellows,

Glad to hear this driver approach might be of some value - hey, it is kinda of fun anyway!

NOTE: If you go with Spences "Driver-MOSFET Boards" don't forget to add the "Transistor" with an
included "Driver" found at the bottom of the order configuration column. Can add a few dollars but
gets the speed up there.

Just make sure you check the processor output and driver input specs (Output Port configuration, etc.
and Driver input levels, etc.).

Spence has some good information of his page as well re: Drivers, FETS, etc..
(He's a good guy - a hacker for the most part, like us! But a good 4 Channel device at a good price.)

I found the connectors and heat sinks were good value for the price as well, but you probably won't need them.
Major (rediculous) price increases for the Littlefuse SiC's and TI SiC drivers forced me to look for something else.

Revisiting Soft Metal Compounds (powdered metal)

Also, looking into a way to make the Rotor/Stator from Powdered SMC - from the fab house it's about $800 per pair
when machined (and a custom mold is way too expensive just for testing different SMC blends).

Found some 950MPa rated bolts and nuts that might provide a good - done-by-hand - mold technique [simple flat
steel plates, seperated by bar stock (pole seperators) and bolted together such that 800MPa (Hoganas Somaloy 1P
or 3P optimum compaction about 800MPa, or whatever) can be applied using just a torque wrench and elbow
grease]. Anyway, we shall see.

The Laser Cut thin metal laminations works OK but there are "way too many" pieces when doing it manually,
and it's a very slow and tedious process. Good for trying different metals but it will take a very long time to complete
these tests.

Anyway, back to work - have a good one!

Thanks again SL,

A quick update on progress:

Installed the IDE and ordered a mosfet board.

Finished the design for the rotor laminate and getting ready to print 4 of them to see how well they fit the stator.

Things are finally moving toward the start of construction on this end.

The prints fit well, no mods needed.
It takes an hour and 10 minutes to print one. 5 down and 31 more to go. 

Also picked up a couple more motors off Ebay today.

Are you guys starting to believe I'm serious yet?

Have a good day everyone.

Got some information from a person (not public) who decided to reproduce Holcomb's patent in miniature. I gave him advice and my vision of how the generator works. The guy already has a control unit with software and the corresponding cores are machined. If I have more information about the results of this experiment, I will definitely inform you. The guy follows the usual logic and I like it.
Sincerely yours.
