چکیده
In this paper effort is made for the torque ripple minimization of 70 W, 24 Volt, 350 rpm, surface mounted radial permanent brushless DC (SPM BLDC) motor. The stator slot shaping is analyzed. The results obtained from FE analyses have been discussed. Design of stator slots have influence upon the cogging torque. Options available for slot designs viz, square type slots, square with curved tangs type slots, round type slots are taken into consideration in this paper. Uniformity of air gap for each type of slot varies so as the torque profile. Results obtained for 70 W, 24 Volt, 350 rpm motor are verified by 200 W, 24 Volt, 1000 rpm motor. Keywords— Finite Element Analysis (FEA), Permanent Magnet, Surface Mounted PM Motors, Computer Aided Design (CAD), Stator Slot Shaping
