The main aim of the article was to present two emerging discourses of contemporary historiography in the field of digital media. In the first example, the authors present the thought of Niels Brügger, called the Web History and Web-minded historiography, which concentrates upon the digital source itself. The other school is marked by the works of Friedrich Kittler and Wolfgang Ernst, and called media archaeology. It underlines the concept of the medium itself as a primary object of research.

The paper presents the mathematical models of dual stator squirrel-cage induction motor, formulated in phase coordinate system and in general transformed space vector form. The two types of models of dual stator induction motor are considered. The control systems of field-oriented control (IFOC and DFOC) and direct torque control (DTC) of the dual stator induction motor have been described and discussed.
