Electric Drives by ZF: The Compact Power Package

As a compact power pack, the new electric drive combines the advantages of innovative technologies with sophisticated power electronics. It features a strong e-motor, delivering up to 200 kW, a differential, a reduction gearbox, drive shafts, a parking lock and, of course, the power electronics and respective engine control software – all from a single source. Compared with current concepts, the improved efficiency results in up to seven percent more range. This means that, with the same range profile, system costs can be significantly reduced. This is because the demands on the drive battery are reduced. The main reason for the increased efficiency is the silicon carbide technology of the power semiconductors with significantly lower switching losses during acceleration and deceleration.

Significantly better performance at partial loads and perfect response are among the advantages, as is the maximum torque of up to 3,200 newton meters. The compact design also speaks in favor of the new generation of electric drives. The gear set and electric motor are located in one housing, and the power inverter and drive shafts are integrated – and all that with lower weight.

All the innovative ingredients of the new electric drive – power electronics, e-motor and transmission – are, of course, also available as individual components.
