[Getdp] Re : Movement of the rotor in rotary machine (Christian Geikowsky)

[Johan Gyselinck]

Hi Christian,

The simplest way to model an induction motor with the FEM taking into 
account the slip and induced currents in the rotor cage, is in the 
frequency domain (supply frequency) with a FE model without movement. 
The movement is taken into account by multiplying the conductivity of 
the rotor bars by the slip value. This agrees with the division of the 
rotor resistance by the slip in the per phase equivalent scheme. 

Greetings,
Johan
