This series includes automotive starter motors, alternators, and related repair parts. The starter motor drives the engine crankshaft via an electromagnetic switch and a high-speed motor, enabling cold starts; the alternator supplies power to the vehicle's electrical system and charges the battery after the engine is running. The matching rectifier bridge, regulator, carbon brushes, and other components are made of high-temperature resistant and anti-aging materials to ensure stable voltage output and reliable commutation. The products cover a variety of vehicle models and effectively solve problems such as difficulty starting, constantly lit charging indicator lights, and voltage fluctuations.
