Passive Conductor

Analysis > AC Magnetic Loads > Passive Conductor

Introduction

This functionality can be used currently to define some bodies as passive conductors. Defining a body as a passive conductor allows the computation of eddy currents in that body. This will enable the calculation of Joule losses due to these eddy currents in the results requests panel. Skin effect is also simulated using this functionality.

It can be used in Transient Magnetic or AC Magnetic solution to define for instance the squirrel cage in an induction machine or the heated part in an induction heating analysis.

Note: This load allows to define only a Passive Conductor without using Circuit Designer. To set an active conductor please use circuit Solid Conductor component.
Note: It is mandatory to assign to the passive conductor bodies a material with an electrical resistivity value and a soft magnetic property.
Note: See Coils modeling for more explanations about the different possibilities of modelling of coils.

The passive conductor can be defined as Open circuit or No circuit element.

Steps for Transient Magnetic and AC Magnetic solutions

For Transient Magnetic and AC Magnetic solutions, to define a body as passive conductor:

  1. Assign a Material with a soft magnetic property and an electrical resistivity to the body
  2. Assign the body to passive conductor load
