Sorry for waking up an old thread. I came past this thread before because I wanted to build an electric longboard, and I build one recently.
I have used a 90A boat esc with a sk3 5055 280KV motor. The esc works good, but I have one problem.
When I release the throttle, coast for a while and reapply the throttle, it is like the esc is forcing the motor to spin at a lower rate. It feels like the coils are firing at the wrong time (without screeching noice).
I have solved this for now by programming the arduino, I use for controlling the esc, to always apply a small amount of throttle so the esc could still sense the position of the motor (I could be wrong but it works).
Does anyone know what could be happening with the esc and motor?
The answer is a few pages back. This esc sucks for E-boards
Well, I will keep experimenting with it, it is running fine at the moment because te arduino tames it.
Maybe I should order a VESC
