For induction motors, calculation of torque versus slip.

What is the difference between calculations with FluxMotor, Flux2D (static) and Flux2D (transient)?

I understand (I think) that with Flux2D transient I have to do it point by point.  But my question is about the method used, and what is included or not included in these 3 methods.

    Bonjour Bruno;

     

    As discussed in our last meeting, the computation in FluxMotor is achieved with AC Steady state application (what is actually called Static). Using this application means that we have to accept the following assumption:

    In addition to that, there is no real movement in this application, we allow using the slip for induction machine, but actually there is no movement, and the spatial harmonics are not taken into account.

     

     

    Using Transient application, it is time dependant, and there is no assumption here.

     

    Howvever, both are finite elements methods based. 

     

    Regards
