Comparative Performances Analysis of Different Rotor Types for PMSG Used in Wind Turbine Application

PMSG provides a high performance, compact size, light weight, and low noise, without forgetting its simple structure, high thrust, and ease of maintenance, allow replacing steam catapults in the future. Most turbine generators at low wind speed are presented PMSGs. These it has advantages of high efficiency and reliability, since there is no need of external excitation and loss of drivers are removed from the rotor. In this paper, a comparative PMSG performance study's with several rotor topology is presented, each topology rotor has its own permanent magnet structure that is width, thickness and angle. These results are obtained by finite element method (FEM); this approach is a powerful and useful tool to study and design PMSGs, as represented in this paper.
