Another issue that I am not sure now, is that whether ESC has a low-speed limit? I Used a Hobbywing ESC trying to drive a servo motor with original coil and connection, Kv of the motor being 15rpm/v. The motor cannot start at 6S voltage.
Yes I observed some variations of Kv depending of the ESC
Also it happens that some ESC are not starting well if voltage is too low.
After starting-running some ESC could go down in voltage or PWM to some
low speed limit.
SLS ESC are very good to go low speed (FOC algorithms with a lot of DSP)
