Wind turbine, gear and generator rotor, coupled with massless shafts.
Note that name and icon of the model are specific, although the turbine model itself is rather generic. The essential type-specific properties are related with torque generation.
An appropriate torque model has to be connected to WindTurbineGear.blades.
No pole pair reduction of equations of motion is performed.
Therefore phi and w represent the mechanical angle and angular velocity.
