A motor winding phase doesn’t partially work, it is either working or not and if that phase is out the motor will not spin. So the ESC will derate the highest phase if the motor still spin in either clockwise or counter clockwise.
Brand of esc?
Reverse is typically 50% of throttle max forward.
Does your ESC have a factory reset?
Does this questionable ESC work with other motors?
Testing continuity only tests the wire not the insulation, need a megger for that and it has to be fully removed from the circuit.
I checked the manual. It is a hobbystar 120amp turbo model, and there is no option for brushed mode, so that's not it. I recall that immediately on powering up the esc there is a quick sound like a surge, or cogging even without any throttle, then the motor starts heating.
I will try a factory reset as I just got the pc link for it.
