Who is building the motors?

[Picard]

Any idea where these are being sourced from? I thought I read somewhere that these were Bosch built but can't find it. Ran across marketing material for Bosch's eaxle (https://www.bosch-mobility-solutions.com/en/solutions/power-electronics/eaxle/) which got me wondering if these are what Rivian is using.

They supply the motor but Rivian definitely isn't using their e-axle. Rivian is using their own dual inverter, reduction gear, and housing.

An old Internet article does show some insights about the motors:

https://chargedevs.com/features/qa-with-rivians-vp-of-propulsion-full-interview/

Charged: Was the motor designed in-house as well?

Richard Farquhar: For the e-machines, we work with a partner to design the core electromagnetics and motor assembly, and then package them into our drive unit. It’s similar to battery modules in that we work with partners to source the cells and then design and develop the modules and pack in-house exactly as we want it.

So, the electric motors are unique to Rivian in terms of how they’re integrated into our drive unit assembly, how they’re mounted, how the inverter connects with them, how the cooling connects with them, and how they’re oriented in our gearbox.

Of course the "partner" turned out to be Bosch. Still no information on the exact model, but it seems semi-custom.
