The world is electrifying everything to achieve'deep decarbonization'and better tackle global climate change.Electric vehicles(EVs)including battery,hybrid,and fuel cell EVs are expected to become the dominant transport medium within the next decades by replacing conventional internal combustion engine vehicles.As one of the key components in EVs,advanced electric machine and drive systems are one of the key enablers for this foreseeable transition to the electrification era.Significant research and development efforts have been made in constantly improving the power density.
