Abstract

The article deals with the formation of a mathematical model of electromagnetic processes in an asynchronous motor with an external hollow massive rotor, on the surface of which are placed the twigs of the screw. The peculiarity of such an engine is the combination of stable dynamic properties of the machine with a massive rotor and the use of thermal energy released from the surface of the rotor to heat the loose material, which is mixed with a screw. A mathematical model of electromagnetic transients is created by automatic generation by inheriting basic features from a model of a generalized electric machine. This approach is based on the theory of object-oriented design. The principles of object-oriented design make it possible not only to synthesize the design techniques of electromechanical energy converters (EMPE), but also to consider their mathematical models in the hereditary succession of the base class and the descendant classes. This will allow us to approach designing as a complex problem, which solves the problem of obtaining parameters and characteristics of EME in stable and transient modes of operation. The automated generation of a mathematical model of an arbitrary type of EME is performed at the design stage. The idea is to form a mathematical model of a particular type of EME from constituent components of the basic model, based on the principles of inheritance, hierarchy and polymorphism. The advantage of this approach lies in the inseparable connection of design (during which parameters and coefficients for MM are calculated) and mathematical modeling in the optimization of EME in dynamic modes. In this case, any changes in the project itself will immediately come to the entrance of the MM block, which is the main condition of CAD in the optimization of EMPE. The advantage of an object-oriented approach to modeling, in contrast to the known methods of classification EMPE, is not only the display of species diversity, but also the support of such classification mathematical description. A complex object-oriented project, which includes both design and related mathematical modeling of transients, enables optimization of an arbitrary type of EMPE, which is the main task of CAD - obtaining the optimal EMPE, which satisfies the set constraints and has the best technical and economic performance.
