  • Rotor and controller mismatch: The rotor and controller of a brushless motor need to be matched to ensure normal operation. If not matched, it may cause overload and short circuit, thereby burning out the motor.Overload: If the brushless motor suddenly encounters excessive load during operation, it will also burn out. This may be due to changes i...
