The Electronic AdvantageElectric drives require no mechanical gear shifting throughout the vehicle speed range. Current and voltage provide the power to the traction motor to deliver the required torque and speed to the motorized wheels while the motor field static exciter to the traction motor provides smooth dynamic application of power. Built-in traction control algorithms optimize drive system performance. Dynamic retarding reduces wear on the truck's primary braking system. Electric drive systems also offer continuous retarding by using the traction motors as generators. In this way, kinetic energy is converted to electrical energy and dissipated as heat in a self-ventilated resistor assembly. | |

| | GE motorized wheel drive systems are designed and built to provide optimal performance in mining operations. Ranging from 120t to 360t, our AC and DC drive systems have field-proven designs and a history of reliability. Compared to conventional mechanical drives, GE motorized wheel drive systems offer lower operating costs and higher haul productivity. The elimination of torque converters, drive shafts, transmissions and differentials reduces maintenance, improves truck availability and lowers life cycle cost. |
