LFG!

Now I have to make it closed loop.

It was spinning a little bit faster than I thought it clean most of the lubricants from bearings :)

If anyone is interested in how this works and its purpose, I recommend watching this video

How does the EFAM work? Localized combustion of electrolytically generated H₂ and O₂ produces a rapid pressure spike for muscle actuation. The gases recombine into water almost immediately via the combustion reaction, enabling fast passive reset and cycling.

The muscles remain cool to the touch, and are safe and compliant, similar to the "dry" nanomaterial-coated fiber muscles we're also building. The oxidation you see also won't be an issue with the new stainless steel electrodes being installed next.

@akashghosh17 It work same is stand alone motor at that size and configuration but most of the performance depends on winding pattern which can be very different beast on what you want to do.

The Dual-Core BLDC MOTOR is open source on my website now. All the CAD files and parts you need to build are also in the description. It is still unfinished, but I shared it so anyone who wants to build or wants help with design and electronics let me know if you need anything.

@fishPointer Knowing this it makes more sense way they choose this name https://t.co/rC3lJwWjc5

@emm0sh It started looking like a part of a video game.

[OMi @ORHEX0]

@brianmccallum Idk I’m trying to looking for something around 100$

[OMi @ORHEX0]

It turned out fine but I need 3 parts out of aluminum so it aligns properly.

[OMi @ORHEX0]

I’m going to 3d print this with PA6-CF and see how it’s go it seems solid.

[OMi @ORHEX0]

@NotEnoughEntrop Still aluminum is way stiffer than PPS-CF

[OMi @ORHEX0]

@_Stocko_ This with wings will be so dope

[OMi @ORHEX0]

@Chris483879 Right now I’m focusing to make it work and stress test it I’ll work on efficiency later on.

[OMi @ORHEX0]

@Chris483879 The outrunner should handle 480-960W and inrunner should handle 760W combined 1700W stable but can be pushed up to 2600W for short amount time

[OMi @ORHEX0]

@JacklouisP I think for most part it’s the costs that no one want build very efficient light actuators

[OMi @ORHEX0]

@Xaraphim I think the problem is ai still can’t understand physical world even human I don’t think understand physical world really will and there is other factors too but we get there at some point

[OMi @ORHEX0]

@stevenuecke Most annoying part is winding stator I have to get some 19AWG copper wire 😩

[OMi @ORHEX0]

I’m going to 3d print this with PA6-CF and see how it’s go it seems solid.

[OMi @ORHEX0]

Almost finished, just need to order parts, and that’ll take some time.

[OMi @ORHEX0]

@TwerskyNachum I post assembly file on my website you can check it out https://t.co/eBktUzpTny

[OMi @ORHEX0]

@TwerskyNachum Those are 3d printed the iron fits around it

[OMi @ORHEX0]

@TwerskyNachum Yeah technically hallbach array is better but cost and assembly is better on back iron standard array .

[OMi @ORHEX0]

@aprolixian Yes for isolation so the copper wire don’t get short and help with vibration also you can put same resin after winding

[OMi @ORHEX0]

Out-runner parts arrived

[OMi @ORHEX0]

Almost finished, just need to order parts, and that’ll take some time.

[OMi @ORHEX0]

@aprolixian It’s laminated stator.
