Built myself a VESC based Dyno system to investigate motor efficiency. This plot is pretty interesting. All runs except red on were at same settings, but default 20khz switching frequency. Red one is at 25khz. I didn’t redetect the motor, as someone mentioned above, but i kinda don’t see that changing anything.
Other than the red line, the color is a ballpark motor temperature guide. Warmer colors are warmer temperatures.
Thought y’all might be interested in some data in the conversation about switching frequency. Not that it matters to everyone, but it’s interesting and important to some.
