Abstract
Increasing demand of electric traction motors and the limited availability of rare-earth elements have accelerated the research for new motor design topologies. Ferrite permanent magnet-assisted synchronous reluctance motor (ferrite PMaSynRM) can prove to be a viable solution. This paper discusses a new parametric model for designing the rotor of ferrite PMaSynRM. The proposed motor is optimized for FreedomCar 2020 specifications. Finite element method is used to analyse the average torque, torque ripple and stress in the proposed design. The proposed motor is evaluated over complete torque-speed profile. Further, use of asymmetric flux barrier and odd slots per pole pair is proposed to reduce the torque ripple and improve efficiency.
