Investigation of Wound Field Synchronous Machines using Soft Magnetic Composites for Automotive Applications
Andreas Carlsson, Christian Sandström, Viktor Josefsson +3
This paper investigates the application of soft magnetic composites (SMCs) in the stators of wound field synchronous machines for automotive traction. While SMCs are traditionally…
Defining the Magnetization State of LCF Magnets: From Material Properties to Motor-Level Metrics
Taha El Hajji, Aleksandr Nadkin, Stefan Skoog +3
Variable flux memory motors, which employ Low Coercive Force (LCF) magnets, achieve extended high-efficiency operation through controllable magnetization states. To address the nee…
Circulating Currents in Electric Machines: Positive Impact of The End Windings Length on Losses
Taha El Hajji, Antti Lehikoinen, Anouar Belahcen
Circulating currents occurring in windings of electric machines received rising interest recent years. Circulating currents represent unwanted currents flowing between parallel-con…
Circulating Currents in Windings: Fundamental Property
Taha El Hajji, Antti Lehikoinen, Anouar Belahcen
Circulating currents in windings refer to unwanted electrical currents flowing between the parallel conductors of a winding. These currents arise due to several phenomena such as a…
