Found this whilst browsing - doesn't have the power output section but explains that it can be used for full power EV cars up to 300A on brushless motors.
Power section not included but could be a cheap starting point
Interesting reading all the same

The froboard is cool, but you need a very bright programmer to get it to work as a vector controller.
Phase advancing (ie. field weakening) could be done, the encoder has enough resolution to do something clever here, but remember that all of the communication to the dash is done by the MC as well. Its a very busy little blighter.
