Slip frequency approach*

The slip frequency approach is used to model working regimes of the induction motors. In induction motors the stator winding generates the rotating magnetic field with angular velocity ω1. The rotor rotates with angular velocity ω2 < ω1. This can be modelled as a motionless rotor placed in a rotating magnetic field with the angular velocity ω1-ω2.
Slip frequency approach In induction motors the stator winding generates the rotating magnetic field with angular velocity ω1. The rotor rotates with angular velocity ω2<ω1. This can be modelled as a motionless rotor placed in a rotating magnetic field with the angular velocity (ω1 - ω2) Rotor Field ω2 ω1 ω1 - ω2

This equivalent model can be simulated by AC magnetic module of QuickField. All you need is to specify the slipping frequency in the stator winding currents.

The slipping frequency approach does not allow the calculation of the eddy currents in the stator.
