Announcing our new "CLUBS" section where you can join or create a Rivian club or group! You can use this new feature to conveniently plan and discuss local events, gatherings or other club/group related topics.
So we encourage you to join (or start) special-interest and regional-based Rivian clubs at: https://www.rivianforums.com/forum/group-categories/clubs-groups.1/
Guess we now know who received order #1?

They are at least AC motors. The inverters must serve some purpose.Last I heard it was DC brushless. Not sure if that's changed?
Inverters would be needed to charge from AC even with DC motors (but the use of DC motors is unlikely for a variety of reasons)They are at least AC motors. The inverters must serve some purpose.
Agree, but I thought we had pretty good confirmation that there were dual-power combined inverters in the drivetrain, one in the front and one in the rear. That helps keep things compact because they only need one inverter to power two motors.Inverters would be needed to charge from AC even with DC motors (but the use of DC motors is unlikely for a variety of reasons)
You still need an inverter to handle charging at L1/L2.They are at least AC motors. The inverters must serve some purpose.
It would surprise me a bit if they didn't use PMSM.Agree, but I thought we had pretty good confirmation that there were dual-power combined inverters in the drivetrain, one in the front and one in the rear. That helps keep things compact because they only need one inverter to power two motors.
I don't think we've ever had confirmation of what type of motors Rivian is using.

From "WHO IS order #1?" Yesterday,
Who else but the Amazing Amazon Man?DuckTruck said:
Not to name names, but I'm guessing the initials of the recipient of order #1 are either "R.J.S." or "Jeff Bezos".
What seems forever ago, at the Denver event I asked an engineer and he told me 4 permanent magnet of their own design, but manufactured by someone else. Of course anything could have changed since then.I don't think we've ever had confirmation of what type of motors Rivian is using.
I wonder if this is similar to what Tesla is using in the 3 and refreshed S & X. I think it is a type of combo induction motor and reluctance motor? I'm also curious what Lucid is using, whatever it is is small, efficient, high torque, and large speed range.It would surprise me a bit if they didn't use PMSM.
As a side note, had a fun discussion (actually he discussed - I listened) with the principal of a renowned race spec inverter/motor company (now part of Borg Warner). They market a "Dual Stack" motor - essentially 2 motors in one housing driving a single shaft - and that requires a dual inverter for a "single" motor. They offer those motor cores wound either serial or parallel (different power curves/characteristics), and they've even done mixed motors for some applications (one core SOM, the other DOM).
Looks like maybe just the primer, but this still gets my bet on the closest depiction to what Launch Green (/brown) will look like.Unless they have changed heir supplier there was a nice screencap of it somewhere I took. Shots below.
Who knows what may have changed over time as original statements were that all 4 motors were identical which no longer appears to be the case. But at one point in time, Rivian had stated that permanent magnet motors were being used:I don't think we've ever had confirmation of what type of motors Rivian is using.

Thank you. As long as the Tunnel is unmolested....I suspect that space under the seat will be limited, but I find the trade off acceptable....Now I just want it now! Can't wait until next Spring.There was no space sacrificed in the Gear Tunnel it was full size. I did not look under the second row seats where I suspect the extra battery capacity would have been. They didn't really want me "studying" the interior anyway....
