I tested the thermal performance at 30A, 60A, and 100A. This was done by setting the calibration current to the desired level, then disconnecting the encoder and having the motor search for the index pulse. This results in the heat being evenly distributed among the 3 phases, as described here: https://discourse.odriverobotics.com/t/testing-forced-air-cooling-with-a-5060-motor/483. I collected data from a thermistor epoxied into the motor windings, and the built-in thermistor on the ODrive board.

Interesting to see.

I did wonder about the lack of heatsinking on the ODrive. Guess it's left open for your own custom requirements.
