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.

Surface plot of the magnetic flux density and contour plot of the magnetic potential.
