Abstract

Cogging torque is an outstanding issue that regularly occurs in the Surface-mounted Permanent Magnet Synchronous Generator (SM-PMSG). Cogging torque is importane! to be reduced because it will generate noise and friction on the generator so it will decrease the efficiency and lifetime of the generator. For wind turbine application, the cogging torque will hold back the production of electrical power. Many methods are developed to reduce the cogging torque. In this study, the authors proposes methods of reducing cogging torque by modifying stator teeth and the permanent magnet of the rotor. three proposed models and a reference model of generator were, simulated using FEMM 4.2 software. The reduction of cogging torque after correspondence with the reference model is modification stator teeth by adding Half-Cylinder anti-notch is 93,3%, a bread-loaf permanent magnet model is 39,1% and a combination model is 78,1% at positive peak.
