how to define synchronous motor parameter such as power?

Hi friend

I work with electric motors and I saw that some motors in matlab simulink do not have any tap in their option window for changing voltage and power for example? I just fund induction motor which I can change its parameters.

How can I deal with it? In synchronous or PMSM there is no place to enter its power or voltage. please help me.

Some machine blocks are implemented in SI units only and the parameters we need to provide are Inductance, Resistance and so on. These parameters can be obtained from a datasheet or from measurements. In power systems, per-unit system is mainly used, and therefore the power and voltage rating is needed.
