Structural Analysis and Characterization of Radial Flux PM Generators for Direct-Drive Wind Turbines

Jaen-Sola, P; McDonald, A S

Abstract

Wind turbine direct-drive generator structures are analysed in order to optimise and reduce mass. A method for modelling key stiffness parameters including a magnetic air-gap stiffness is outlined. Different approaches are used to parametrically calculate structural stiffness and mass. Finite element and analytical techniques are used to model mode 0 and mode 1 deflections and these can be used along with parametric models of electromagnetically active material.
