If you're studying I would recommend you program your own simulation. There's quite a bit you can do using the equivalent circuit. The book by Krause has many numerical programming examples (although it's not by any means easy reading... mostly just sits on my shelf).
Is there a specific type of problem you're looking to simulate? Current/torque during motor starting is a fairly straightforward one. I can provide the simple algorithm of that if you want (I've already done it on this forum somewhere).
Thanks electricpete
no i want a general simulator of electrical machines
to study their behavior in different cases and effects of
change in their structure on the electrical Specifications.
