The span/length of the cantilever beam across the wind tower are different at every level. They are longer at lower base then on the upper levels. The reason is that the tower can support more bending moment at lower level and also the bigger the spread of the turbine blade, the more efficient/power generation comes from the generator.

Electromagnetic and Thermal-Fluid Coupling Analysis of an Interior Permanent Magnet Motor for Electric Vehicles

IEEE
This paper proposes a coupling analysis of the electromagnetic and thermal-fluid fields in an interior permanent magnet motor for electric vehicles. Both electrical and magnetic materials have temperature-dependent properties. The power loss produced by the electromagnetic analysis reheats the motor and its rise in temperature alters the material properties as well as motor performance. The temperature-dependent power loss is used as a heat source to create a lumped-circuit thermal model in terms of equiva
