Thank you. Yes I am on the other side its good now. papers are signed. And I can be excited about the future again.

Thank you. It already has.

No not at all. Its X19M5556 from epic resins many Major OEMs use it for this very same thing!

Been there done that. Sorry It has a lot of limits as well. Potting is hands down the best way to go. You don't need to "service or modify" the windings the only thing needing service is the bearings and I can still get to them. With oil it will find its way out. It will wick up the wires... leak past o-rings etc. You also then have to seal it super good and get the right amount of oil in so you don't cause a tone of drag on the rotor and then you need to allow for thermal expansion and contraction. Its a LOT harder to deal with. On top of all of that Oil doesn't conduct heat nearly as well as this potting.

This potting has a thermal conductivity of 2.2 W/mK and Oil has a thermal conductivity of .125 W/mK so this will conduct heat out of the windings 17.6x as good!

Not true. The whole de-gauss the magnets from too much strength is a old wives' tale. Its never happened in real life. There will be limitations for sure but I am not worried in the slightest about demagnetizing the magnets. Heat is a bigger concern but with them buried in the laminations of the rotor they won't get as hot as a SMPM motor. There is 2 parts to these motors and its big reason we had to add MTPA. You are not just using the stator to push and pull on the magnets but you are also pulling on the rotor iron like a SR motor. As for RPM these are geared low already I already spin them to 15000 rpm. Many people had no idea I would be able to get 300hp from these but I have proven that in another video. As the motor approaches saturation the inductance drops and that will be a challenge but with the split windings to each controller it will help by making the inductance 2x.

I will with a single set of phase wires in time.

The problem is the 6 phase wires are not as perfect as I would like them for something I am planning to put many miles on. But time will tell how this works out and how I can support them while routing them to the controllers.

The potting compound is X19M5556 from epic resins and its 2.2 W/mK

Thank you. Yes. Some things have happened in the last 10 months I can't talk about right now. But I am getting things organized to keep building amazing stuff.

Awesome! Thanks for sharing! 😊

Yes. I spent a lot of time looking at Datasheets to find something with the best thermal conductivity but still could flow as much as possible. Vacuum chamber would have been next to impossible. Non the less simply getting the heat from the end turns to the case quicker should be a big win when I really push this thing.

Keep it up! I've been a big fan for years. Good to see you back to work posting some projects.

@@cheapygeek Thank you. I am still here. Just trying to find a path forward with some personal stuff which I will share at some point. But this stuff and my boys are what makes me happy and they love helping with as much of this as they can.

By machine I mean a larger sawmill

I also got someone on FB trying to steel the Arlin account asking for a reset code thru my phone number

@@Doctorbasss Yeah i have been hacked Anyone knows how to get it back that would help a lot
