ABSTRACT

An investigative three-phase asynchronous machine mathematical model is proposed, validated and derived in this paper. This paper investigates the dynamic mathematical model of pseudo reference frame theory of three-phase to two-phase conversion for the asynchronous electric machine (three-phase induction machine) by using Clark's transformation. In this paper, also studies mathematical derivation of the hypothetical machine, primitive machine and behavior of asynchronous machine with the two-phase operation. A system of different reference frames and related transformations (three-phase to two-phase) is investigated for the presentation of asynchronous machine equations, which enchanting knowledge of all winding MMF equations. This contains transformations of three-phase to two-phase rotating reference frames and a novel transformation to two axis components. These transformations decrease to the already well-known transformations of generalized electrical machine modeling and analysis theory. This article also provides the mathematical equations of a three-phase to two-phase transformations using natural reference frame theory for an asynchronous electric machine. Reference frame theory, a mathematical model for approximating the equivalent circuit parameters of the asynchronous machine from the readily available performance characteristics is presented.
