Abstract: Axial switched-flux permanent magnet ( ASFPM) motor combines the characteristics of axial flux permanent magnet motor and flux switched motor. With its advantages of short axial length, compact structure, high power, high torque density, and convenient heat dissipation, it was widely used in electric vehicles, electric aircraft, wind power generation, and other fields. The typical topology structure of ASFPM motors was introduced, the research status and progress was wummarized in motor design and analysis methods, cogging torque suppression technology, loss and thermal performance analysis and optimization, control technology, application analysis, and other aspects at home and abroad, and the current application situation of this type of motor was analyzed. Based on the current research status of ASFPM motors, future research directions were discussed.
