Good morning please:how can i determine all the caracteristics usefull for the simulation of a synchronous rotor coil machine ? and how can i simulate it in Matlab 12.5 version?parameters speed(500tr/min),12 pole pairs,torque(4394N.m) thanks

I'm in fifth year of engineering mechanical and I for memory of end of study design of a multiplier power electric. The electromechanical system that was given to me to do is to design a gear reducer (torque multiplier) and then I use these new settings to size an alternator mount new characteristics. the settings that I have given in the question are the values to the entered the alternator. How to simulate an alternator rotor wound in 12.5 Matlab version. please help me Sincerely
