I have the motor sitting on my desk and I can't get it running with the OEM controller. It looks like running after market controller is the only way to get it running, but I don't know what controller would work.
If you can't talk to the OEM controller, you can rip it's brain out
and control it directly from a different brain (you just have to figure out the gate control and current sensor wiring).
I do not know if the brain I am using will work with an induction motor (probably says in one of the Lebowski threads), but if it will:
I'm doing this now with the Lebowski brain in a Honda IMA inverter over here:

The thread isn't finished yet, because I'm trying to document it well enough for anyone that wants to to do the same thing, or adapt to any other big-EV inverter that they can determine where the signals need to go, but Kiwifiat, Tomdb, and others have already verified that this system works.
The brain is a little more than $100 shipped depending on where you are, from Kiwifiat, and you already have the inverter. If you had to use a different inverter, then depending on what power level/etc you need, you might even be able to use the Honda IMA inverter, which can be had for under $100 shipped, if you poke around or wait. Or there's others (Volt, Prius, etc).
The brain can be used sensorless, or with UVW hall sensors for startup, though you'd need an encoder converter for those. Kiwifiat is also working on some encoder to hall converters but I don't even remember what kind of signal they convert from, so you'd have to look at his posts for that info.
If the brain does not do induction, the code has been made open-source, so if you know how, you could rewrite it so it *would* do induction motors.
