Comparison of electrical machine types in hybrid drive trains: Induction machine vs. permanent magnet synchronous machine

Abstract

The intention of the present paper is to draw a reasonable comparison of two different types of electrical machines for use in a parallel hybrid drive train: the induction machine with cage rotor on the one hand, the permanent magnet synchronous machine on the other hand. Both machine types have been designed for application in a mild hybrid vehicle. By dint of simulation models and a total vehicle simulation system the machines were compared on their different loss behavior during several driving cycles to find out which one meets the given demands.
