From: Kiril on 28 Nov 2009 04:08 I have a project to simulate a fault in induction motor rotor. The fault can be from broken broken bar for example. I try my best in simulink but i can't manages with this problem. So i need help, this project is very important for me. So could someone hlep me to simulate a fault of AC motor in simulink model using powelib or simscape? Thanks to anybody who try to help i really appraise it !

Ooo no!!! So what to do. Do u think that i need to chage the program. Bey be there is any soft which is beter than simulink's powerlib ???

Hi, it is not a problem of the software! The problem is to calculate the parameters for the faulty machine. With such faults you described you no longer have a 'symmetrical' machine for which the machine parameters can be easily calculated. The machine representation (model) is normally a job for engineers of design departments of machine manufacturing companies (concerning the faults you mentioned). Even if one gets the different parameters from someone who knows you will still have to check if these parameters can be used for the 'standard' models delivered with any simulation program. Sorry to tell... Frank

Yes i understand now. And my last question is from there i can find this model or may be some help to start makinh it by myself in simulink.?? |
