Abstract :
The influence of various design parameters on the cogging torque developed by permanent magnet machines is investigated. It is shown that the slot and pole number combination has a significant effect on the cogging torque, and influences the optimal value of both the skew angle and the magnet arc, as well as determining the optimal number of auxiliary teeth and slots
