" Highly Dynamic Drives for Electric Hybrid Vehicles - Electric Machine Design and Dynamic Test Method "

e-mail: yury.loayza@iea.lth.se

Electric Hybrid Vehicles (EHVs) play a crucial role in the development towards a more environmental friendly transportation. An alternative to solve some actual challenges with hybridization of vehicles is studied at the Division of Industrial Electrical Engineering and Automation (IEA) at Lund University in cooperation with the automotive industry. A key component of this drive train is a highly dynamic Electric Machine (EM) which will make possible to hybridize a conventional car at reduced costs while maintaining the performance and comfort of the vehicle.

The first part of this thesis work describes the design and optimization process of this multipurpose EM and presents the final prototype.

The second part of this thesis presents a convenient, fast and precise method for measuring the mechanical and electromagnetic properties of this EM and similar motors. This Dynamic Test Method is based on state of the art control and measurements system and makes possible to characterize an EM without the need of a Brake Bench.

Finally the measured properties of the EM are analyzed and the results show that the EM has the required performance in speed, torque and dynamics for the intended EHV application.

The results of the thesis reduce the need of heavy and expensive components for the EHV and for the measurements, by using very fast, dynamic and accurate tools instead.
