    damaged sabvoton 7280 SVMC7280 (M)

    Also, regarding "If you do have to replace the controller, you might consider a sensorless-capable (that can still use hall sensors if the motor has them) controller so that you can use it whether or not your motor's sensors work, and save the trouble of opening the motor up for that part." - my...

    amberwolf, thank you so much for the information. YOu have provided very detailed and realistic scenarios, out of which I believe the following is what happened: "With some timing problems (some combinations), the motor can appear to operate correctly, even faster than usual sometimes, but get...
