Hi all,
I have a model of an induction machine, which is attached in the file. In this model, besides stator and rotor laminations there are still holes located in the stator lamination that I try to make to change the rotational iron loss in the machine. These holes may be for ventilation system. Assuming that, across area of holes is kept constant. But the shape and position of these holes will influence the magnetic flux density as well as magnetic field strenght, then resulting changes on iron losses of the stator core. Therefore, to find an optimal position, we need an optimization method in the comsol model.
Based on this, I have some questions that I need your help.
1- How to build up a iron loss model (or hysteresis loss model) in the induction motor model? So far I do not know how to obtain iron loss distribution in the model. I want to compare iron loss distribution with and without holes.
2- Is it possible to adopt an optimization method to obtain optimal location of holes, which offers a minimum iron loss. Genetic algorithm can be used or developed in Comsol? Is there any references about this?
I believe that there are some guys interested in this problem and having a lots experiences on it with Comsol. I appreciate your help or useful comments that we can learn together.
Thank you so much.
Best,
