Check the motor
Check for burnt or melted wires or wire connections attached to the motor. Burnt or melted wires or wire connections indicate that the motor has overheated and may have caused the plastic insulation to melt from the motor’s electromagnet copper wire windings.
If the insulation on the copper windings melts, they will short out and cause the motor to not run or run slowly. Shorted motor windings can also burn out the speed controller because the speed controller has too much resistance, causing it to overwork and overheat.
