Modeling Maxwell Motion Eccentricity

You can model motion eccentricity for Maxwell 2D and 3D transient designs that have cylindrical rotational motion set up. Ansys Electronics Desktop provides a Maxwell Eccentricity Wizard with settings for

• rotating part eccentricity
• rotation axis eccentricity

For rotating part eccentricity modeling, the eccentricity is only applied to rotating objects, not to a motion axis. More specifically, these rotating objects are all objects enclosed by the band, but not the band itself.

For rotation axis modeling, the eccentricity is only applied to the motion axis, which is equivalent to moving the band itself, but not any rotating objects inside the band.

Using these two basic settings, you can model the following physics.

• Static eccentricity: To model static eccentricity, you need to set the rotating part eccentricity and rotation axis eccentricity to the same values.
• Dynamic eccentricity: To model dynamic eccentricity, set the rotating part eccentricity values only.
• Mixed eccentricity: This is the combination of static and dynamic eccentricities. To model mixed eccentricity, set both rotating part eccentricity and rotation axis eccentricity, but with different values.
