The TGNR128 is a high-efficiency alternator engineered for modern internal combustion engine (ICE) vehicles, including passenger cars, light commercial trucks, and hybrid powertrains. It delivers 14V DC output at 130–150A, providing reliable charging for 12V battery systems under varying engine speeds and load conditions. The generator features a dual internal cooling fan design that enhances airflow through the stator and rotor, significantly improving thermal performance and extending service life—even in high-temperature environments such as tropical climates or heavy-duty applications.
Constructed with flame-retardant materials, the TGNR128 meets stringent safety standards and reduces fire risk in case of electrical faults or overheating. The stator outer diameter is φ128mm, ensuring compatibility with existing vehicle mounting brackets and belt systems. With a weight of only 5.6kg, it offers excellent power-to-weight ratio while maintaining structural integrity under vibration loads.
The unit operates reliably across an extensive temperature range of -40°C to +125°C, making it suitable for extreme climates—from Arctic winters to desert summers. Its IP55 protection rating ensures resistance to dust ingress and low-pressure water jets, protecting internal components from road debris, rain, and wash-downs. The regulator brush assembly uses a maze-seal structure to prevent dust and moisture penetration, reducing wear and maintenance frequency.
Efficiency is optimized through advanced magnetic circuit design, achieving >72% efficiency with minimal parasitic losses—critical for fuel economy and reduced emissions. The generator supports multiple regulator configurations: single-function, multi-function, or LIN bus-compatible regulators, allowing flexibility in integration with modern vehicle electronics. Optional snow-shedding diodes prevent voltage spikes during sudden load changes, while steel pulley or OAP/OAD designs provide compatibility with various belt tensioning systems.
