Our high amperage alternators are made of high quality materials with good abrasion resistance, high temperature resistance, corrosion resistance and aging resistance, which can make them durable and have a long service life Pure Copper Windings Made of high quality materials and pure copper windings. They have excellent electrical conductivity and magnetic properties, allowing for efficient energy conversion and long-lasting durability. Precise Balancing & Calibration The rotor and stator of our alternators are accurately balanced and calibrated to minimize rotor and stator imbalance and vibration, thereby increasing generator stability and service life. Advanced Materials Rotors and alternators are made of high-performance materials such as special steels, aluminum alloys and electrically conductive materials. These materials have excellent thermal and electrical conductivity and mechanical strength, allowing them to remain stable at high temperatures and high operating speeds.
