Generator in 3D

Application ID: 462

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 flux densities.

The core is surrounded by several blocks of a permanent magnet made of samarium and cobalt, creating a strong magnetic field. The stator is made of the same nonlinear material as the center of the rotor, confining the field in closed loops through the winding.

The model calculates the static magnetic fields inside and around the generator, where the nonlinearity of the magnetic material is modeled using an interpolation function.

This model is included as an example in the following products:
