Steps for iron losses computation on regions

This section describes the steps to carry out iron losses computation on regions:



  1. Choose a Computation type: On regions
  2. Select laminated regions for iron losses computation
  3. Choose:
    • Fix values for geometric parameters and I/O parameters
    • In transient magnetic: time interval to obtain a time period. This choice is linked with the field Part of cycle described by the time interval
  4. In Transient magnetic, define the time period selected in the previous step. The various possibilities are presented in the table below:
    Choices Description
    Full cycle
    The user have to choose a full electrical period in the time step interval. A periodicity indicator is displayed in the result gui box of the iron losses.
    Note: The first two steps of the scenario are hidden as they cannot be selected for this computation.
    Half cycle (advanced mode)
    The user have to choose a half electrical period in the time step interval. A periodicity indicator is displayed in the result gui box of the iron losses.
    Note: The first two steps of the scenario are hidden as they cannot be selected for this computation.
    The rebuilded signal is antiperiodic.

    Note: Half cycle option can manage a signal with a DC component.
    No cycle Flux does not take into consideration the period.
    Note: For the LS model, there is also a " hysteretical " transient for the first selected step, it appears because the point is living the B(H) solving curve (first magnetization curve, anhysteretic curve etc.) to match the rebuilded B(H') hysteresis loop during iron losses computation.
  5. Choose losses model:
    • Model defined in material
    • Modified Bertotti: Enter the coefficients values and modify exponents if necessary
    • LS predefined sheets (in transient magnetic): Enter the sheet iron
    • LS defined by importing of a MILS file (in transient magnetic, see LS model identification with MILS )
