Electrical machines with concentrated winding topology for automotive applications


Thanks to its elegant compact structure concentrated winding topology started to be a very attractive choice in automotive industry. This quality reflected often in smaller weight/volume and higher efficiency is mainly due to short end-turns which are the main source of extra weight and losses in machines with classical distributed winding. Moreover, concentrated winding accompanied with other corresponding technologies (like segmented stator) allows obtaining a super slot filling factor up to 75% leading again to more compact and efficient machine.
However, many challenges show up with this winding topology related mainly to harmful thermal and structural effects caused by parasitic harmonics often exist in such winding magnetomotive force (MMF).
The aim of this presentation is first to justify the interest of automotive manufacturers in concentrated winding topology for hybrid applications at all its new levels/scales (Full, Mild and Baby). After, we will focus on main related challenges (losses, noise…) and possible solutions or more precisely tradeoff, at the end, to obtain the needed performance.

About the speaker:

aslanBassel Aslan received the M.S. degree in electrical engineering from the Ecole Normale Supérieure de Cachan, Paris, France, in 2009, and the Ph.D. degree in electrical engineering from Arts et Métiers ParisTech, Lille, France, in 2013. His doctoral research dealt with the design of multiphase PM machines with fractional slot concentrated winding and wide speed range. From 2013 to 2015, he worked as a research and development engineer at Valeo, Créteil, France, where he was involved in the topics of electrical machines for automotive applications (new generations of high performance efficient alternators and machines for Mild hybrid applications). Currently he is responsible of electrical machines development in Formula One car at Ferrari S.p.A, Maranello, Italy.
