ZF-TERRA+ Integrated Generator System

ZF's integrated generator solution, the ZF-TERRA+, comprises a powerful electric machine which is integrated into the transmission housing.  

• Serves as a powerful power source for electric loads when operated in generator mode
• Up to 5% in fuel savings can be achieved through power-on-demand operation of electrified auxiliaries on the tractor
• CO2 emissions can also be reduced together with a boosted productivity and tractive effort 
• Can be operated permanently in generator mode to provide, depending on the size of the electric machine, up to 70 kW of power 
• If applied as power source to electric drives, can yield fuel savings and increased available power 5 to 10% through better efficiency compared to conventional hydraulic drives
• Electrification on the implement enables new design concepts on the implement through flexibility in the arrangement and installation of drives
• Can be converted to a powerful parallel mild hybrid system if extended by an energy storage unit such as a hybrid battery
• Extension through energy storage unit enables typical hybrid functions such as stop/start with powered auxiliaries, short term boost of the engine, and stabilization and smoothing of engine operation
• Use as a hybrid system creates additional degrees of freedom, allowing further improvements of fuel consumption, exhaust emissions and performance when used with intelligent power management 
• Placement within transmission enables easy integration of separating clutch to decouple the generator/hybrid module from the engine
• Allows for easy integration of a planetary gearset for increased power output
