Example Models

Simulating a Generator Made From Nonlinear MaterialsSimulating a Generator Made From Nonlinear Materials

This model is a static 3D simulation of a generator having a rotor with permanent magnets. The center of the rotor consists of annealed medium carbon steel, which is a nonlinear ferromagnetic material that is saturated at high magnetic...

Simulating the Moving Parts of a GeneratorSimulating the Moving Parts of a Generator

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...
