Abstract

This paper investigates the influence of some parameters on the cogging torque developed by directly driven permanent magnet synchronous wind generators. It is shown that many parameters have the influence on cogging torque and the slot and pole number combination has a significant effect on cogging torque. A simple factor has been introduced to indicate the effect of the slot and pole number combination. The simulation and experiment results verify the effect of the proposed method.
