N2 - Modular arc-linear flux-switching permanent-magnet motor (MAL-FSPM) used for scanning system is researched in this paper by the finite element method (FEM). The MAL-FSPM combines characteristics of the flux-switching permanent-magnet motor and linear motor. It can replace the reduction gearbox and kinematic mechanisms and can realize the direct drive and limited angular movement. Structure and torque characteristics of the MAL-FSPM are analyzed. Torque ripple is mainly caused by first and second harmonic of cogging torque during the whole operation. Based on the principle that torque ripple is reduced without decreasing the average torque, width of medium stator module and width of left and right non-magnetic material are optimized to reduce first harmonic of cogging torque, and the second harmonic of cogging torque is reduced by first harmonic current injection. After the optimization, torque ripple reduced by 72.43% and 45.65% for dend> τp and τp >dend>0° and average torque is approximately unchanged.
