Abstract

This paper presents an application of the pole shifting technique used for reducing the cogging torque of permanent magnet synchronous generators (PMSGs) that employs in micro wind turbines (MWTs). The effectiveness of the pole shifting technique on the cogging torque reduction of the PMSG has been tested by the cogging torque measurement system that has been connected with a MWT. In order to evaluate the performance of the proposed technique, two internal rotors for the PMSG on the measurement system, namely internal rotor with the pole shifting and internal rotor without the pole shifting, have been designed and fabricated. The measurement results and analyses have showed that the PMSG with the pole shifting has a very low cogging torque when comparing to the PMSG without the pole shifting.
