Resumen:
The design of electric traction motors is a complex task since
high-performance requirements must be met in terms of power and torque
densities in the wide operation speed range, including volume and mass
restrictions. Since the launch of the GM EV, in 1996, electrification
has been increasing and hybrid and electric vehicle fraction motors have
incorporated constant improvements and very innovative designs. This
paper reports on motor specifications of 16 of the most representative
commercial hybrid and electric vehicles, additionally, presents a
comparison of their special design features and performance. Although
there are plenty of technical publications on electric traction motors
and some of the commercial motors presented herein are very well known
in detailed, the authors develop and present a finite element method and
Ansys (R) Electronics Suite comparison, which is based on efficiency
maps. The results show the chronological evolution of different
mechanical configurations that have successfully been arranged to
improve the performance of fraction motors over the years. The main
conclusion is that the geometry of the magnetic circuit is one of the
most important characteristics and that high optimized designs are
needed.
