OSU electric motor

Not sure if this has been posted already, but NutsandVolts (aka Kyle's) old alma mater has been busy working on a crazy motor.

Basically a giant outrunner, but using induction instead of permanent magnets.
Magnax is a very similar machine, but I gather they are using axial flux, versus the OSU's radial machine.

The windings are neat, but also, how's the inverter being part of the stator?! Exciting times.

Thanks for the heads up Jones. Interesting. The stator coils appear to be well over half conductor length as end-turn. But then again, that portion is of larger cross sectional area so mitigating resistive loss.

I wonder how they fabricate the inside out cage on the rotor. Be awfully large for a die casting. But unsure how else they could use aluminum.

Glad to see CAR at OSU advancing. I did some work with them years ago. That was using the induction motor from a donated EV-1 on a hybrid SUV competition. Even back then, nice facility and good people.

Very interesting

Am I reading this right? No winding insulation (anodised?)? SIC MOSFETs? 43200V?!
