Hybridization effect on generation capability of an embedded CPA

Abstract

The purpose of this paper is to compare performances of two configurations of an embedded Claw Pole Alternator (CPA) where the excitation winding is transferred to the stator side. These configurations are: the Simple Excited Automotive Alternator (SE2A) and the Hybrid Excited Automotive Alternator (HE2A). Performed study is based on test at no-load and under load operation regimes, using Magnetic Equivalent Circuit (MEC) models validated experimentally. It has been found that the hybrid Excited claw pole alternator provides higher performances, due to the increase of leakage flux through the integration of permanent magnets between adjacent rotor claws.
