Well this is exciting news, finally our small dedicated team has created prototype full featured high power high performance motor controller. The schematic, bill of materials, all the code .. all open source
This controller hardware design is built on a long long history of controller design for commercial and military aircraft, sport performance fully electric car build experience and hard core engineering at its finest. by forum members Arlo, nitrousnrg, Highhopes & Maxi (code monster from Endless Sphere). The four of us founded www.powerdesigns.ca
to centralize the work so if you’re interested to learn more about us or EV technology please check us out! a Very special shout-out to Benjamin who’s VESC software the Axiom controller is based on; #respect.
The Axiom control board has a lot of built in flexibility for various motor position feedback methods, communication and supports a wide range of voltage and current applications. This particular embodiment was paired with 650V 600A rated IGBTs mounted on a cold plate with a large format brick capacitor (metalized polypropylene) custom designed for powerdesigns.
It was put on the bench for functional verification earlier this year and new code features have already been added and merged into the wider VESC project. We’ve since produced a handful of prototypes for our early adopters who graciously agreed to put the board through the paces in their particular application.
Since this forum is all about DIY and we love the DIY culture, we made this controller open source and wanted to post it here in the hopes you will find it useful for future builds. Want to code up your own features or need to modify the CANbus comm to fit your application, no problem! Its open source, YOU have all the power. We're just cleaning up the schematic now to get it ready for a near future post so keep an eye out for it. the datasheet too will be posted soon.
