Magnetic–Structure Interaction in a Permanent Magnet Motor

Application ID: 119361


In this example, the coupling between Multibody Dynamics and Rotating Machinery, Magnetic for performing electromagnetic and mechanical analysis is demonstrated. A permanent magnet motor with 10 rotor poles and 12 stator slots is modelled in 2D. The magnets are attached to the circumference of the rotor. To model magnetic-structure coupling integrated with moving mesh, the electromagnetic force is transferred to the rotor, and the rotor motion is transferred to the moving mesh. In a time-dependent analysis, the magnetic flux density and displacement are computed for three complete electrical periods.

This model example illustrates applications of this type that would nominally be built using the following products:
