#### **Abstract**

The undergraduate electrical machines course belongs to basic courses in electrical en‐ gineering. It is especially crucial for the students studying continuing subjects like electrical drives and control of electrical drives. Thus, a good knowledge of the behav‐ ior of electrical machines in various control modes and various supply and the changeable parameters of machines is needed to understand the behavior of ma‐ chines. This chapter deals with the development of virtual models of two electrical machines in MATLAB GUIDE: an one-phase motor and a stepper motor. It serves as a guide for similar applications; only the necessary explanation of the machines opera‐ tion and their mathematical models is presented, which creates a core of developed virtual models. The graphical user interfaces contribute in modernizing the electrical machines course and in enriching their attractiveness by a fast and comfortable visual‐ ization of the machine performance at their changeable control modes and parame‐ ters. They also serve as an introduction to the measurement of real machines in the laboratory. Of course, the teacher is expected to clarify the obtained graphical results and phenomena running in real machines corresponding to the machine behavior.
