This information is part of the Modelica Standard Library maintained by the Modelica Association.
The radial cylinder model is characterized by the outer diameter, , the inner diameter, , length, , and the angle . The magnetic reluctance is determined by:
In this model the magnetic flux and the magnetic potential difference, respectively, are radially oriented.
The above figure left shows a radial flux cylinder with . The figure on the right indicates the central angle in case a cylinder section shall be considered.
