A couple of friends and I just bought a large pile of Yasa axial flux motors and controllers at Makani's going-out-of-business auction.

Makani was a Google X company that spent a lot of money on wind power kites:
and yesterday open sourced all their code, including motor firmware:
https://github.com/google/makani/tree/master/avionics/motor

The motors are similar to and larger than the Yasa 750R:
YASA 750 | YASA Limited
which is an axial flux motor rated at 790Nm peak torque, 200kW peak power.
The Makani controllers have exotic 1700V SiC half bridges, I've posted a teardown here:

We are now working on getting the Makani controllers operational using the open sourced firmware, and also building our own control board using TI Instaspin to drive the Makani power stage. Here's a video of the first spin using a lab supply with a TI LAUNCHXL-F280049C and BOOSTXL-DRV8320RS:

I am very interested! I also got one of the Yasa motors but no controller. I also got a Protean motor.
