Electric Machine Design Tailored for Powertrain Optimization

In spite of being highly efficient, battery electric vehicles suffer from limited driving range because of the limited battery capacity. This disadvantage can be encountered by optimizing the powertrain using a special electric machine design. The main idea is to increase the efficiency of the electric motor especially in those operating points, mainly used in relevant driving cycles. This means, the motor has to be optimized for low-load operation. In addition to this efficiency improvement the electric motor will be even more cost-effective. The impact on the entire powertrain concerning technical and financial advantages will be shown.
