This piqued my interest as it has an integrated DC-fast charge and OBC circuitry, CANBUS controlled, and seemingly cheap. I was able to pull the wiring and connector information for USDM, but it looks like the wiring may also include parallel wiring for Type 2 ports/CCS. Connector service numbers ar...

Thats basically a PTFE lined seal on NBR or FKM. Good option for those that wants to try that. Pics shows the pitted shaft surface has already been sleeved. Was that a prior DIY rebuild? If so, what sleeve was used and is any material hardness info known? Mine has not been rebuilt, as far as I can ...

@dzolotnyuk bought the following from AHP. https://openinverter.org/forum/viewtopic.php?p=46191#p46191. Failed quickly with speedi-sleeve. Actually I don't understand the design of AHP's SB20 seal, its a classic asymmetric angle V shaped seal which relies on compression on v tip to provide pumping ...

Shaft cleanup will happen later today, we'll see what it looks like. I was able to pick some residue off the seal lips to reveal which looks like virgin material. Gray and black flakes, similar to graphite-impregnated material. But the lips are STIFF. Which I could see definitely being an issue as t...

Serial is T13, so 2013. I haven't been able to clean up the shaft yet and my picture doesn't convey the thickness of the build up of the PTFE on the shaft. It almost seems like the bond between the seal and seal body failed vs. wetness on the shaft or corrosion at the encoder. Have we seen any other...

I've contacted US Seal with a design envelope and application information (without being 100% explicit to avoid potential CoI). I also tore-down my 50k mile donor for my project. RevE (non-reman) had the triple seal, no inverter wetness and maybe a drop or two by the encoder. Blue G48 coolant. There...

- Larger diameter = higher surface speeds. 40mm over 30mm at 10k RPM is +5m/s (40mm = 20.9m/s 30mm = 15.7m/s) so there will be more frictional heat. True, but have found several seal MFG that quote 40 m/s on dry lube PTFE within spec. Pushing to 40mm diameter @18k RPM puts as at 37.7 m/s surface sp...

All make sense. However, the rotor's shaft locks in 30mm diameter and ~8mm seal width so these can't be changed. Only remaining design variables are material + shape + shaft surface prep. Thinking about this aspect, what if we COULD make the sealing shaft diameter larger? I.e, a machined aluminum a...
