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