I’m curious about the drive unit on the Rivian R1T. MotorTrend has a decent article about the whole truck, and says that it’s a permanent magnet motor. But it doesn’t say what the arrangement is. Does anyone here know if it’s a radial flux (a fairly normal looking arrangement) or an axial flux (more of a pancake shape)? There’s not a ton of shots of the drive unit out there, and regardless, the motor seems like a pretty compact little unit.
I don’t know what it is, but I love the idea of axial flux motors. They seem stupidly small for their potential power output. For example, the YASA 750 has a peak of 582 ft-lbs of torque in a motor that weighs ~82 lbs. (Continuous torque is still 295 ft-lbs of torque, which is still impressive for a motor that weighs not a whole lot).
