농형 유도 전동기 내의 로터바 설계

Abstract

A rotor bar in an induction motor for electric railway is studied from a design viewpoint. The design process is divided into two stages; conceptual design and detailed design. In conceptual design, overall configuration is determined. A computer program is developed for the conceptual design. Various formulae are developed for analysis. They are derived from elementary and advanced elasticity. Design equations are made from the formulae and they are programmed with Graphic User Interface (GUI) for user convenience. Structural optimization is adopted for the detailed design. Finite element method is used for analysis. A design problem is defined to minimize mass or maximum stress while constraints are satisfied.
