SRFirefox: The Makani SiC half bridges are 1700V, not 1200V. I was originally very keen to try an Axiom control board with the Makani power stage. And then Arlin told me the expected price of an Axiom would be $6500 (!). For that price I can buy a Rinehart, a Sevcon Gen 4 Size 10, or any other controller. And a TI LAUNCHXL-F280049C is $30, and does pretty much everything the Axiom does except for some optoisolation. Most of it on chip. So thanks but no thanks on the Axiom. IMHO, motors should be driven with realtime control system hardware, not a zillion interrupts on a general purpose micro. But what do I know?

Yes, on the Makani Yasas, the entire CNC aluminum case spins (i.e. outrunner). There is a splined hole in the center and plenty of places to bolt to the spinning cases as was done for the Makani dyno coupling. Transmission? Not needed: 3250 rpm on a 16" tire is 100 mph, enough for me. I am planning to run 2 of these where a differential would be, each driving an IRS half shaft. Should be fast enough that stacking is not needed.

Hey @vanhoivanbinh, you can mail me and we can talk about this. We might have a spare Yasa motor. Best email for this would be my handle here, followed by ""
