Very low airgap flux density

Hi

First I would like to thank you for your time reading this post. I am trying to simulate a 36 pole hydrogenerator to assess its EMF and harmonics. What the attachment contains:

1. geometry, electrical and physics

2. solver steps

To run the program, simply mesh the domain and then use the test scenario. The problem im having is that the airgap flux is only 0.3T which is totally wrong. I have deleted all stator winding electrical circuit and simply treating the project as a rotor with windings with no other electrical circuits. I am trying to simply the study and see where the problem is but unfortunately i was unable to get a sensible airgap flux density. would someone please help?

 

regards

Marcus
