Design aspects of low cost electric machines used for highly integrated starter-Generator Systems

This paper describes design aspects of low cost electrical machines used for highly integrated 48V starter-generator systems. It is shown that a belt-driven interior ferrite magnet machine with integrated power electronics and controller is a good solution for micro and mild hybridization approach. Considering the given automotive constraints and requirements, a machine design optimisation process is used that employs finite element analysis. An electric machine prototype is realized to validate the simulated design.
