Pamic Alternator GTA41 is for Komatsu 930E-4 and 830E-AC trucks. It has rated power 1700 KW at speed 1900 RPM. The manufacturer in China has served these mining alternators for 15 years with hundreds of repairs. All components of our alternators are new and compatible with OEM. We are the only supplier of this alternator in the aftermarket.
We use the best quality silicon steel sheets for stator and rotor with high magnetic conductivity and low energy consumption. High quality alloy steel 42MoCr is used for shaft that has higher tensile strength than OEM after quenching and tempering. Stator and rotor insulation are processed by VPI(Vaccum Pressure Impregnation) treatment twice to reach Class H of 180C degree.
The air inlet and outlet frames are made with resin material, same as OEM. Resin material resists vibration better than sheet metal. As a result, our frames has long working life.
Alternator weight 4200 KG, packing crate dimension: 234x176x210 CM.
