Looking for some thoughts on this data. On my dual vesc based dyno, i'm getting this data when changing switching frequency. Anything other than 20khz is distinctly and repeatably lower efficiency than 20khz. Why would this be? Is there something in hardware or firmware that's preset for that switching rate? Anyone have any ideas?
Interestingly, the test motor seems to be more stable and consistent above 20khz, but less efficient.
Could get more data easily with community setting recommendations in VESC-TOOL.
PS, this is with a FSky 6.6.
