Object Oriented Mathematical Modeling of Electrical Machines

This paper is concerned with the implementation of the concept of automated synthesis of electric machine mathematical models, depending on design and type of the latter. The proposed method of the mathematical model synthesis is based on the provisions of the object-oriented design theory, which is widely used in the field of information technology. A generalized electromechanical energy converter, a squirrel-cage induction motor, a synchronous motor, a DC motor and a transformer are considered as a reference. Due to the application of the object-oriented concept of hierarchy and inheritance, each individual electric machine is generated from a generalized electromechanical energy converter with the simultaneous synthesis of equations describing electrodynamic transients in the form of a product of parameters and currents matrix. It is proposed to use the practical application of the technique under consideration in the optimization of electrical machines in dynamic operating modes during the computer-aided design process.
