Hi folks,
For some months I've been working on a fork of VESC thanks to resources of pymco.fr and paltatech.com The original VESC is an open source inverter for up to 50v and around 3-5kw motors, and Benjamin (vesc creator) helped me adding firmware support to this new hardware.
This one decouples the control logic from the gate drivers, so we can use an external gate driver for high power applications. We have a second revision working with 600V 600A IGBT modules and +/-460A current sensors, with an extensive set of hardware protections to avoid fires related to firmware bugs.

For a quick glance at the schematic, here it is

And layout is here

Design files are in the github repo

This board is made with kicad, an open source EDA. Head to
http://www.kicad.org for more info about that.
Screenshot of the user interface, IMO the best GUI out there.

And a quick video to show it spinning a motor. Its not a big motor, its not a good video either and needs some finer tuning, but that will happen on the real motor.
