Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

The axial cylinder models is characterized by the outer diameter, , the inner diameter, , length, . The magnetic reluctance is determined by:

The area of cross section yields:

A hollow cylinder is depicted in the above figure left for . A solid cylindric flux tube an be considered by setting the inner radius, , equal to zero.

A circular sector of the area of cross section with central angle is depicted in the above figure right.
