Introduction. The basic mathematical model for the electrical machines. Parameters for electrical machines. Transformations of the original mathematical model for machines (C,F,H,G,D,B,E and T). Electrical machine types. Park’s equations. Operation inductions (reaction) and the time constant of the synchronous machine. Stationary and quasi-stationary condition of the synchronous machine. Stationary condition of the asynchronous machine- the equivalent scheme. Simulation of the asynchronous machine supply. Models of asynchronous machines for method of field orientation control; electricity and voltage supply; rotor flux orientation; the analogy with the direct current machine. The model of the synchronous machine for field orientation control. Simulation of non-stationary processes in direct current machines. Non-stationary processes in synchronous machines. The synchronous machine model. A three-phase short circuit of the synchronous generator. The asynchronous operation of the synchronous machine. The non-stationary condition of the asynchronous machine. The physical explanation of the motor starting process. The analysis of the asynchronous machine starting in real environment.

Classes are carried out either as lectures or as exercise classes. The lectures use modern illustrations for the intuitive understanding of the subject matter. For the full understanding of the subject matter, the auditory exercises supply examples that accompany the lectures and encourage the students to independently solve engineering problems. A part of the exercise work is carried out in the computer laboratory.
