Design, Analysis and Prototyping of a Flux Switching Transverse Flux Machine with Ferrite Magnets

This paper presents a novel Flux Switching Transverse Flux Machine (FS-TFM) topology. This new topology is well suited to use low cost ferrite magnets in a flux focusing design to achieve high torque density. An electric scooter traction motor featuring the proposed topology is designed using soft magnetic composites through 3D finite element analysis. Design optimization and analysis are conducted regarding cogging torque, efficiency, power factor, and demagnetization. The designed FS-TFM has extremely low cogging torque, high torque density even with ferrite magnets, and moderate power factor. A prototype motor is under construction to verify the motor performance through experimental evaluation. Benchmark comparison shows the proposed topology is promising for lowcost, direct-drive applications.
