Hi,
I'm using a B-G431B-ESC1 to control a drone motor. My motor draw around 300W at maximum power. I have done a FOC firmware with Motor Workbench and it works very good with the load (propeller). I use sensor less speed feedback.
But when I remove the propeller and try to control the motor, it start to turn and after around one second, it do a very bad noise and stop with a speed feedback error. The read speed is around 7000rpm, but in fack it was around 250rpm.
When I have the propeller the sensor less speed sensing is very precise.
Do you have some ideas to help me ?
Thanks :smiling_face_with_smiling_eyes:
