摘要
TO reap potentially substantial economic and environmental benefits,the transportation industry is now moving towards electrification,with electric vehicle,all or more electric aircraft,high-speed train,subway,ship propulsion,maglev,etc.,being prominent examples.When selecting electric propulsion systems,the cost,reliability,efficiency,maintenance,durability,weight,size,vibration and noise are all considerations,thus bringing great challenges to the design of machines and controllers in electric propulsion systems.Therefore,novel machines and controls in electric propulsion have been hot topics in the last few years。
