Abstract

This article presents the redesign of a traction motor of an Electrical Rear Wheel Drive (E-RWD) unit, modifying its torque and power capabilities in order to improve the vehicle efficiency with given drive cycles in a hybrid vehicle application. It is shown that a peak-to-average power ratio of 3 is suitable and that this is best accomplished with a reduced slot area in combination with cooling ducts in the stator back. The geometrical compromises made are deeply discussed and illustrated.
