Scaled Prototype of a Redundantly Fed, Gearless PMSM Wind Generator with Tooth Coil Winding and Solid Rotor Yoke

Electromagnetical and thermal models are derived and the nominal operating point is analysed in both domains. The loss components that feed the thermal model are calculated from transient electromagnetic 2D-FEM simulation. The thermal model consists of two coupled 2D models: A 2D-FEM simulation for the stator and a thermal network for the rotor. Axial effects of the temperature distribution are discussed and analytically calculated.
