Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

- Rotor temp is hard to measure (no direct contact) This seems to be a huge research area including many tech papers and patents filed to estimate. Tesla's 2010 patent ( https://patents.google.com/patent/US8773058B2/en?oq=20120007532 actual invention might be a couple of years before patent filing ...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

Lots of people are not fans of waterless coolants for that reason: with water being "1", glycols typically have a thermal capacity of around .68-.72. In the ICE world so very many people seem to be chasing cures for overheating, and waterless coolant just isn't the right fix for almost al...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

This gearbox has 10:1 ratio. Starting with high RPM motor all the way to driving the half shafts. Its a wide range to trade off efficiency (thinner ATF) to high wear protection (multi weight gear oil for rear diffs such as 80w-90) LDU also has no damper for the applied torque (ICE's gradual torque ...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

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. You had a question previously following your conversation with a seal supplier - I was just trying to help. A 3...

Re: Tesla Large Drive Unit (LDU) Motor Teardown and maintenance

Thanks. Indeed, it was something like feet/min. Basically amount of surface area over time period which makes total sense. So now we've got 7 seal interest which is great. However, been thinking more on doing own seal design.... - The most important factor is probably seal material (PTFE blend) and...

Yes, they sell engines and batteries only if they install them, but it seems to me that with the right to repair, the sale of the oil seal is really necessary, because it's just wrecking, changing the whole engine instead of replacing the rubber according to the regulations To give them their due :...

VAG have an online portal for service information: I think for around 10€ per hour to download info required.

Re: Subaru Legacy Estate (diesel)

The Leaf design is my ambition. Like the GT86 conversion but attached to the 4wd transmission. From what I can find the 450h gearbox is just 50bhp, hardly enough for a 1.5 ton estate. The GS450H is apparently the same as the LS600H but without the transfer case. The LS600H motor peak power is 165Kw...

Re: Subaru Legacy Estate (diesel)

Far too complex, mechanically and electrically for me. I don't even want to think about how the speed of the two motors would be varied. I think the 450h parts would be very rare here. Not exactly a big seller. Subaru diffs and gearboxes are good for over 400bhp so 200 from the Leaf should be fine....
