    Hello,
    I am not sure what exactly is your "some difficulties".
    If you have queries related to drawing the section in the pre-processor then
    a little practice should do! If you are thru with your model and if you have
    already assigned material properties ..... then in the main Menu click on
    Problem and set the frequency value to zero(for zero-slip conditions at
    no-load analysis). On the Boundary Condition - if you have modelled the full
    machine set the outer most trace(outer periphery of the stator frame) to a
    Dirichlet Boundary(A=0). Group the stator conductors as phase belts. Assign
    currents to these belts as per 3-phase convention(I presume it is a 3-phase
    m/c). Click on Mesh / Create Mesh. Next Click on Analysis/Analyze. When you
    are finished with the Analysis Click on Analysis / View Results.
    In your next communication to the group, you may consider attaching your
    model so that members could get to know where your problem is wrong !!
