Thing went on and I found something to solve this question, and I just want to share with you my experience: PMSM (single phase) was too simple for my project, a better solution is FEM-Parametrized Rotary Actuator.
Whith this block, you can provide a flux mapping table .. phy = f(i;theta) (flux function of current and rotor position). I get the tables using FEMM and a matlab scrpit, but I think there could be some example tables.
Whith this solution .. I get the cogging torque, and for example, if I set a random initial position, the rotor, in the simulation, move to the minimum reluctance position without any current at the input.
Create x,y coordinates of an arc using the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_create_an_arc.3F.
Then pass those coordinates into poly2mask(x,y,rows,columns) to get a binary image (mask). Then multiply that by, or assign, the image to mask off everything except that sector.
Let me know if you can't figure out the attached, well commented code.
