PROJECT TITLE :

Experimental Characterization of a Belt-Driven Multiphase Induction Machine for 48-V Automotive Applications: Losses and Temperatures Assessments

ABSTRACT:

This paper presents the simulation and experimental results of the tests conducted for losses and temperature assessments on a belt-driven starter generator designed for forty eight-V mini-hybrid powertrains. In specific, a double 3-phase 10-kW induction machine has been selected as the appropriate candidate for the applying. This paper reports and discusses in detail the experimental calibration of the lumped-parameter steady-state thermal model, significantly regarding the warmth transfer thermal parameters. The testing activity has been conducted on a water-cooled prototype. Therefore, the validated thermal model has been used to predict the thermal behavior of the prototype at totally different load conditions in accordance with the planning specifications. In the ultimate half of this paper, some concerns regarding the prototype packaging and the embedded power electronics thermal issues also are reported.
