FEMT 2023: X Factor

Introduction

The X Factor allows the user to adjust the iron losses to his measurements and recompute the efficiency of his motor with a better accuracy. The X Factor is a floating value by which the iron losses amplitude is multiplied.

The X Factor can be accessed:

  • before solving: in the Input Parameters
  • after solving: in Post-process with a New Command
The X Factor is only applied to Iron Losses. The maps impacted are:
  • Iron Losses (Rotor + Stator) in Torque-Speed Area
  • Rotor Iron Losses in Torque-Speed Area
  • Stator Iron Losses in Torque-Speed Area
  • Total Losses in Torque-Speed Area (including Iron Losses)
Remarque : Iron Losses are computed only with MTPV and MTPA modes, not with MTPA Fast and MTPV Fast modes.

So with MTPA Fast and MTPV Fast modes, the X Factor is not available.

Steps to define X Factor before solving

The X Factor parameter has been added to the list of Input Parameters.

The default value is 1.

The X Factor will be applied when a new test is run.

  1. Open your FEMT component generated by Flux
  2. Configure your inputs, including the X Factor parameter

  3. Run the test by clicking on

    → Solving is launched

    → After solving is complete, maps are computed and displayed

  4. Post-process the results

    → You can see the Iron Losses maps and Total Losses maps impacted by the defined X Factor value

    → The X Factor value used appears in the Inputs table corresponding to the test in the middle area

Steps to define X Factor after solving

The X Factor can be modified after a test has been run. It allows you to quickly obtain a new test with a new set of values, which you do not need to solve again. It is simply a matter of recomputing the values of the maps to be displayed, taking into account the new set of values for the possible parameters (including the X Factor).

  1. Edit a test already solved and click on Post-Process with new values for the command

    → The Post-process with a new command dialog box opens

  2. Enter the new X Factor value and validate

    → Maps are rebuilt

    → After rebuilding, the new maps are displayed

  3. Post-process the results

    → You can see the Iron Losses maps and Total Losses maps impacted by the defined X Factor value
