Analysis Features

|
| COUPLING WITH THERMAL ANALYSIS |
| JMAG enables the coupling of thermal analysis, both steady state and transient, with the magnetic/electric field solvers. Direct coupling allows the temperature dependency of the magnetic and electric properties to be included in an analysis. |

| COUPLING WITH STRUCTURAL ANALYSIS |
|
JMAG's structural analysis module can calculate stress, vibration, centrifugal force, contact and sound pressure. The forces calculated from the magnetic field analysis can be applied directly to the structural model. The magnetic field analysis can also include the stress dependent properties of the materials, with stresses derived from a stress analysis. In addition, eigenvalue analysis is available as a separate feature.

| INDUCTANCE CALCULATION TOOL |
|
JMAG has the capability to calculate the inductance of transformers, busbars, reactors, and motors which have complex structures.
Analysis of busbar and reactor JMAG's partial inductance tool calculates the inductance for each conductor region, including busbars with complex geometries. The calculation of the inductance at each current value is possible, taking into account the nonlinearity of materials. For reactors, the inductance can be found at an arbitrary transient current including not only static current but also carrier harmonic. |

| PARAMETRIC CALCULATION TOOL |
|
The tool runs multiple parametric calculations using a set of parameters for the geometry or conditions that have been specified in the user interface.
