Characteristics Improvement Possibility of a High-Speed Linear Induction Motor Designed by using Eigenvalue Analysis of Electromagnetic Force

Abstract

The purpose of the investigation to be described is to examine the effectiveness of the design technique (called EVA method) for electromagnetic force maximization problem. EVA, an acroym for Eigen Value Analysis, is an approach to elucidate the essential characteristics of an electromagnetic apparatus. In the research on linear induction motor, it has become a common belief that there hardly exists an active way to prevent entry-end and exit-end effects. However, the EVA method has possibility to give a practical and effective solution to this problem. The pesent work reveals the improvement possibility of the thrust characteristics and braking characteristics of an acutual high-speed linear induction motor
