Hey guys,
recently I purchased a Motenergy ME1401 motor which comes with a sine cosine resolver sensor. I replaced the sensor (RMB29AC) with the same chip that outputs 4 pole UVW commutation outputs (2x commutations per revolution, sensor model RMB29EB).
I connected this to a fardriver ND72260 to run and it doesn't rotate properly. In the settings I selected 4 poles and also did a auto learn sequence for like 5 mins (it wouldn't rotate, it just either sits there and snap between 3-4 points). after exiting autolearn I tried running and it does run, it spins but it sounds like it's grinding something or like a engine running, it doesn't sound normal at all. I'm not exactly sure what the problem is. I tried all sorts of phase wire configurations and hall configurations. I've attached a video of what it sounds like in order help show what the problem is.
I am now suspecting it might have something to do with the cogging torque of the motor being to strong ( it takes serious power to turn the shaft by hand even one indent when nothing is connected to the phase wires). I know this might be a bit ridiculous but im kinda out of options and don't know what to do at this point.
