Torque ripple is produced in PM motors because of non-sinusoidal distribution of flux, saturation, improper selection of slots etc., these ill effects will deteriorate the starting and steady-state performance  ...  In this proposed work, the cogging torque analysis and torque ripple analysis of permanent magnet motor and line start permanent magnet motor has been done and reported.  ...  Because design methodologies like fractional slot pitch winding, slot skewing are minimizing pulsating torque production in sinusoidal PMAC machines and minimization pulsating torque leads to trade off  ...
