This is a look inside the actual PMSRM motor of the Plaid drive unit. This is essentially the "Raven" drive unit which itself is a repackaged Model 3 PMSRM rear motor. The main change for Plaid was upgrading the rotor for higher speed operation by incorporating a carbon-fiber overwrap to keep the rotor from coming apart at 200 MPH/320 KPH.
The Motor itself with stator/field, rotor and housing only weighs 99 LBS/45 KG. The rest of the drive unit adds about 110 LBS/50 KG for a total of about 210 LBS/95 KG.
UPDATE: No need to tell me about ATF9 availability. I've since learned that ZF now specs Pentosin ATF9 for it's new 8/9 speed transmissions which are being used in a lot of cars, so now it's becoming easy to find. But in 2017 when Tesla started using it, this was not the case.
