  • Sent back for re-inspection
  • Motor was tested OK
  • ESC was found to have damaged MOSFETs. See below photo.

 

  • Technically, there were a couple of possible causes of this type of failure.
    1. Reverse polarity
    2. Motor signal bridged and shorted
  • We will provide this one time courtesy support by replacing the sensor unit on the motor, and rebuild the ESC with all now internals.
  • We replaced ESC control board, MOSFET board, and capacitor module (waived $100 cost).
  • We tested and verified the ESC with our motor. Please see RMA#1505 bench testing video.
  • We soldered customer’s motor with the ESC to perform test again. Please see RMA#1505 motor and ESC testing video.

 

Final note: while we checked the motor, we did see excessive solder drop on the motor tabs. Please see the below photo.

At this point it is very difficult to make a judgement for the true cause of the failure. We can only provide the facts that we observed from the motor and ESC. We’d like to remind that reverse polarity and motor bridged can cause permanent damage, and not cover by the warranty. We hope this courtesy service will fix all issues for you.
