Simulating a Generator in 2D

In this model, a rotor with permanent magnets and a nonlinear magnetic material rotates within a stator of the same magnetic material.

The generated voltage in windings around the stator is calculated as a function of time. COMSOL Multiphysics models the rotation with assemblies and identity pairs, using a prescribed rotation coordinate transform in the Moving Mesh application mode.

The nonlinearity of the magnetic material is also considered using an interpolating function.
