Liebherr expands its portfolio of electric travel drives

After presenting the first electric version of the eFAT 325 travel drive at Agritechnica 2015, Liebherr has further invested in the development of electric travel drives. The portfolio has therefore been expanded to include three further gearbox sizes in a series-production range of electric travel drives. The new range includes four different gearbox sizes: from eFAT325 to eFAT500. The special gearbox design enables even load distribution across the individual stages, thereby ensuring high power density. The convection-cooled, short-time submersible permanent magnet motor with IP67 protection achieves performance specs of 7.9kW to 50.8kW in one hour of continuous operation. The range as a whole is distinguished by high torque in a compact construction thanks to the permanent magnet technology. The latter enables tailor-made placement of the drivetrain in the cramped conditions of the machine. Which eFAT to choose depends on the maximum required traction force of the machine, ranging from 186kN to 559kN.
