Root cause: Power motor malfunction due to backlash or mechanical binding

Diagnostic procedure: Manually rotate the motor shaft. If resistance is detected or foreign objects are present, replace the motor immediately.

Main causes:

 Potential causes:

 ①Overweight flight

 ②High-temperature operation leading to current overload

Cause of occurrence:

Check if the motor is jammed, leading to excessive output current and the temperature reaching the motor's critical value.

Troubleshooting method:

Inspect the power motor for any foreign objects causing obstruction, allow it to cool down for a period, and then restart. If the fault persists, please replace the power motor.

Cause of occurrence:

There is a communication anomaly between the main controller and the power electronic speed controller, rendering it unable to retrieve relevant information from the power motor section.

Troubleshooting method:

Inspect the communication harness between the powertrain and the main control link to ensure it is functioning properly. Check the main control port for any signs of adhesive failure or detachment.
