3-phase rotating machine ...help plz

Please login with a confirmed email address before reporting spam

hello
I'm gratuate school student. and beginner of Comsol..
I wanted to make 3-phase Motor.
So I have tried to simulate Motor since 3 weeks ago.
But All of occations is failled.
So.. I was so disappointed.

plz help me. how I fix my file.

and then
I have some questions.

1. how to rotate machine automatically. I knew to simlate rotating machine that I shoud put Prescribe rotation velocity. and then put the number in rps blank. but I think this situation is not Motor but Generator. Is it right? and the how should I do?

2. what differents between Prescribe rotation velocity and Prescribe rotation.

3. how I should do to show 3 phase Motor in Time Dependent. I can't show Contour of Time Dependent. In other words, 3-phase didn't operate correctly.

4. flux of Magnet doesn't come out in Result of Contour. why do that?

Sorry I can't write Discussion, because of my language skills.
plz help me how I should do!
thank you!
