Curriculum Vitae: Dr.-Ing. Wilhelm Hackmann
Dr. Wilhelm Hackmann studied electrical engineering at the TU Dortmund / Germany (focus: electrical machines) and got his diploma degree in 1991. He worked as a development engineer in the railway traction drive development of AEG, Adtranz, Bombardier in Berlin and Wiener Neudorf from 1992 up to 2004. In 2003 he finished his PhD Thesis at the TU Darmstadt / Germany (wheel hub traction drives in street cars: induction machines, permanent magnet machines, transverse flux machines). Since 2005, he is head of the motor design / simulation department of the e-traction drive development and principal expert ‘Electrical Machines’ of the company Continental in Berlin.

Abstract of the lecture:
Electrical traction drive systems for passenger cars have to fulfill  extremely high requirements regarding performance and costs. In order to achieve the optimum cost-benefit ratio the drive systems have to be realized in regards to the right performance levels (just needed for the vehicle operation to avoid over engineering), with good harmonized single components, which are designed with technical standard solutions (capable for an automotive series production). The series production has to be scalable and also flexible for application. Different e-machine types with different properties can be used for such drive systems.
In this lecture besides some base remarks different e-traction drive concepts (here: integrated axle drives for EV and 48 V belt driven starter generators) including the special requirements for the drive projecting, the electrical design and the performance capabilities of different e‑machine types are presented in detail. Furthermore relevant e-machine measurement procedures, including advanced investigations regarding noise and inverter-induced bearing currents, are introduced. Finally an outlook on imaginable future work topics is given.

Important Note:
The lecture will be presented in German.
