Abstract :
This paper presents the calculated and the measured performance capability of a cage rotor induction machine used as a direct connected, crankshaft speed, combined starter-alternator for an automotive diesel engine in an experimental hybrid electric vehicle. The calculated results are based on a nonlinear equivalent circuit model of the machine in which saturation is considered only in the stator and rotor magnetizing flux paths. The development details of this model are given as well as several sets of calculation results for a prototype induction machine. Finally, measured maximum performance results for the test machine are presented and compared with model-based calculated results for the same operating conditions of speed, terminal voltage and current
