In the paper, an integrated design for electric drives is presented. The design is based on a high-speed approach and on ASM technology to answer future demands. In the paper steps of electrification are outlined and the terms micro hybrid, mild hybrid parallel, full hybrid, plug-in-hybrid and electric vehicle are defined. Development goals are changing in electric vehicles, efficiency, weight and acoustic behavior becoming important. As efficiency can be only reached by considering the whole chain of power transformation including inverter, motor, gears, an integrated approach is necessary. The solution developed by ZF is presented. The EVD1 (Electric Vehicle Drive 1) is a light-weight, compact, power dense and acoustically optimized high speed solution. The concept has been integrated in several prototypes and is being evaluated. First test results show that the high-speed asynchronous electric motor concept has advantages concerning efficiency, weight and acoustics.
