1 Answers
Car starter motor failure signs are: 1. Difficulty starting; 2. Unstable idle speed; 3. Prone to stalling, inability to accelerate when power is insufficient; 4. Excessive fuel consumption, high emissions, and audible clashing sounds between the starter drive gear and flywheel teeth. A damaged car starter motor can prevent vehicle startup and requires timely inspection and repair at a 4S shop. The function of a car starter motor is: Through energized coils generating force in a magnetic field to rotate, it drives the starter rotor to turn, and the small gear on the rotor drives the engine flywheel to rotate, thereby turning the crankshaft to start the engine. The starter motor consists of three parts: a DC motor, transmission mechanism, and electromagnetic switch.
