In a steady state 2D/Skew session, when user wants to design an induction motor and display iron losses versus slip.

Before solving, user must create an I/O physical parameter SLIP, controlled via a scenario.

Next, the Flux project must be solved with a multi parameter depending on SLIP.


  • Scenario name
  • Slip parameter name
  • Face region name (stator cores or rotor cores but only one)
  • Hysteresis loss coefficient (in W s / T 2 / m 3 )
  • Classical loss coefficient (in S / m )
  • Loss in excess coefficient (in W / ( T / s ) 1.5 / m 3 )
  • Thickness of lamination (in m )
  • Stacking factor


  • Curve of Bertotti losses vs slip
