This is really exciting, congrats on the launch! Exciting to see engineers coming from college engineering teams like FSAE -- I was a member of a solar boat racing team, which is a very similar problem space and also relies on "stacking efficiencies" in your drivetrain system.

If you don't mind, I have a few questions about how you collect data and evaluate the performance of your motor quantitatively. Do you have any particular software stack for data collection? I see the motor communicates over CAN -- Is that just to send control signals, or do you also expose sensor readings like temperature, power input/output, etc? Lastly, did you need to write any custom software to collect/visualize motor performance and what does that look like?

The reason I ask is because I'm in the early stages of building a data collection & analysis platform for experimental hardware (https://www.telemetryjet.com/), targeted at small engineering teams or individuals. I don't want to focus too much on what I'm building (this is your thread!) so I'll just say in general I'm really interested in learning more about how small engineering teams like yours collect & utilize data in the engineering process.

Congrats again on the launch.

CAN is pretty typical interface for inverters & drives. We communicate the commands via CAN and receive currents, temps, speed, torque, and errors back via CAN. We are using PCAN systems at the moment. In the past, GUIs that I have used are Kvaser, Vector Canape, ATI Vision, and LabView. A lot of our post processing is done in MATLAB, Excel, or python. Feel free to reach out directly if you would like more insight.
