An attempt to improve the sizing of a hybrid excited brushless claw pole alternator

Abstract

Purpose – This paper aims at the improvement of the generating capability of a hybrid excited brushless claw pole alternator (HEBCPA).Design/methodology/approach – Following the identification of the HEBCPA influent sizing parameters, the investigation of their impact on the back‐EMF production capability is carried out considering a 3D‐finite element analysis (FEA).Findings – The HEBCPA Back‐EMF production capability is highly affected by the variation of the influent sizing parameters. A selected combination of these parameters has led to an optimized generating capability.Research limitations/implications – An experimental validation of the generating performance computed by 3D‐FEA shall be treated in the future.Practical implications – The optimized HEBCPA is of great interest for the automotive applications as well as for wind energy generating systems.Originality/value – The optimized HEBCPA is a new concept that has been proposed by the authors in a recent work.
