So here’s a theory. what if one motor is a few KV lower than the other. my primary is 184kv vs 182kv on the secondary ( according to lambda based calculation from FOC detection of lamda) or 175kv vs 170kv (according to BLDC detection + kv command in vesc_tool )
the primary has the higher kv, the higher temp, and the descrepancy is largest when i as at 95% dutycle for a stretch at the beginning there.
blah. words.
