This thesis reports on a study and research activity carried out at Dayco S.r.l.. The aim of this work was to set up a BSA bench configuration in order to perform immediate efficiency measurements on different Front End Accessory Drives (F.E.A.D.) layouts. The whole activity is part of a global picture directed towards the CO2 emissions reduction. On this type of bench, a BiSG (Belt Integrated Starter Generator) hybrid solution or P0 architecture of an internal combustion engine is replicated: consists of a 12 or 48 V electric motor directly inserted in the F.E.A.D. and substituting the classical alternator. The bench is equipped with a three-phase synchronous electric motor that simulates the functionality and load conditions of an internal combustion engine.
