Abstract

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 performace 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.
