I have spent some time recently making some improvements to the potting press that I had used in previous iterations. I made it so that I can use machine screws to close the press tightly, which should make it much easier to fit it in the vacuum chamber, and the pressure should be a bit more...

Thanks for that suggestion. I definitely got a cheaper quote from CNC Madness than I did from Send Cut Send. Also, they mentioned that they have 0.2mm carbon fiber too after reaching out to them. I think this design will work well. It's still solid enough to wind around. The holes should...

I would imagine it might be conductive, but insulated from the enabled magnet wire. I am not sure it it would impact the performance or not. It's a good question. Thanks for the pointers. I made some changes to the design again and added voids per your suggestions. The voids correspond nicely...

After a few more iterations. I landed on something I think I like. This is 3 phases, with 5 turns each and It's just a little under 2mm thick. I only added the "gear teeth" between each phase instead of each turn, and was able to get them to pile up next to each other nicely. Obviously I need to...

The last attempt at the Faulhaber winding was just a test. After tweaking things a few times, I managed to make this. This is two 3d printed pieces that I glued together. There are three turns on each phase, still 12 poles. I decided to give up on the stranded wire. I switched to a 24 AWG...

Lately I have been helping another maker with some simulations and found some information that might be obvious. But ideally the halbach array is tightly packed (minimize the gaps between poles, but also that the halbach magnets are the same width and height as the axial ones. Heres the data...

In paralell to testing the one working motor, I have been working on the next version. Even though I had already made a set of rotors that has yet to be used (due to not being able to get the center piece machined). I found that there was actually quite a bit of space between the inner...

Thanks, I have been using the "calc apply old" for my manually entered values. I believe that I had incorrectly calculated my resistance values, but to no avail. I have been playing with HFI, also with no luck yet. Admittedly all the settings are a bit beyond me, I am slowly trying to learn...

Yes, but the numbers that appear are pretty wacky when I do that. I have to imagine it has something to do with the bad resistance reading, but I'm not positive. I have had the most success using calculated values and adjusting

So I have purchased a VESC (finally). Its the VESC 6 EDU from Trampa boards. I got the VESC tool as well, and have started to wrap my head around it. I think I have a decent understanding of the basic FOC settings, but I am unable to get it to start sensorless. I have measured the Kv (Spun...

So would this be a power equation? I used 12, which was voltage. But if it's power, would it be power from the power supply? Or something other value? If it's from the power supply it's 12vx4A=48w P=I^R Then 48w=I^2 * 0.3117 I = ~12A Am I missing something?

Thanks for the input :)

Thanks for the feedback. Phase to phase resistance is not something I have been able to measure accurately. But based on the parameters of the conductor. I have calculated it at 0.31177 Ohms. I'm not sure how to get current from that, but I would assume its just V= I * R 12 = I * 0.31177 I...

Soooo I still have yet to fix the pressure pot. But I was able to make some progress in others ways. A while back someone reached out to me after my last YouTube video. They ended up making a part for me but due to the 3D printer optimized design, it was not right when it was made out of...

While winding it went great, tying it down was a huge pain. The find that had pulled in close together made it very difficult to get the thread where it needed to be and it was all so tight that it kept breaking the kevlar thread. I could potentially get thicker thread, but I think the real...
