This paper presents a design strategy of Concentrated Flux-type Synchronous machine(CFSM) with ferrite permanent magnets (PM) as a substitute for the rare-earth PM. The design strategy is to apply eccentricity or chamfer to the rotor. Applying eccentricity or chamfer to the rotor decreases the back electromotive force but reduce the torque ripple. Eccentricity or chamfer is applied to the same rotor area to compare the torque ripple reduction effect. The back electromotive force and torque of CFSM with eccentricity or chamfer are calculated by 2-D finite element analysis. As a result, the optimum shape model with eccentricity reduces the torque ripple by 8% compared to the chamfered model.
