A COMPARISON OF THE THERMOHYDRAULIC PERFORMANCE OF VARIOUS ROTOR COOLING TECHNIQUES FOR AN IPMSM

open access: yesProceeding of International Heat Transfer Conference 17, 2023
Abstract: Electric vehicles are gaining popularity in the transport sector due to growing concerns over climate change. The driving range of these vehicles remains a challenge and higher power densities are therefore needed, which leads to higher heat fluxes. Proper thermal management is crucial to prevent premature breakdown of the wire insulation and
