I've been using a Vesc (HW v4.12) for some time now, it worked really well with a brushless motor with HALL sensors.
I recently decided to change the motor and use a smaller one (also with Hall sensors), but it doesn't work very well.
Now, when in FOC sensored mode, the motor won't switch to sensorless mode when it reaches the "sensorless ERPM" speed. So the default value being 2500ERPM, the motor won't spin faster than that, it will only start to vibrate and make more noises when I tell it to spin faster. Also when below 2500ERPM, the speed control performs very poorly (lots of vibration and oscillation).
Did anyone had this problem too ? and know how to solve it ?
