An optimization method with three objectives: total power loss, weight, and torque ripple, and with one constraint for a minimum acceptable value for the power factor, is described. The design examples are for a direct-drive generator rated at 3 MW and 15 rpm. . ption makes for the best modern wind turbine drive trains is still going strongly. In t ighted like mechanical structure, thermal behaviour and electromagnetic structure. In order to reduce the cogging torque and electromagnetic torque ripple components, the air core topology has. . Abstract— This paper presents a multi-objective design optimization for a novel direct-drive wind turbine gener-ator. The design considerations presented in this paper are rotor eccentricity, short circuit current estimation, voltage refl ction at generator terminals due to high frequency switching and forces during. . Subsequently, an in-depth internal modeling, focusing on the electromagnetic behavior of the designed generator, is executed using finite element analysis (FEA) through the Ansys Maxwell RMXpert software.
