Mathcad files for electrical synchronous motor

I am looking for Mathcad files that deal with synchronous electric motors (non-salient poles and salient-poles).

These files should include fundamental mathematical equations for the motors and the calculation of their characteristic curves.

A few years ago, I had access to this type of file, created by Mr. Roman Miksiewicz of the Silesian University of Technology (Poland).

Unfortunately, the files I have do not cover synchronous motors.

If you have such files, could you please provide them to me as Mathcad "xmcd" files, as I do not have Mathcad Prime?

I am a retired engineer and volunteer my time helping students with their studies.

Thank you in advance.
