Abstract

This paper presents an examination of leakage and end effects in a linear synchronous motor used as a drive for a vertical transportation system. By means of finite element computation the effect of a skewing of the motor on the propulsion force is calculated. The influence of horizontal displacements of the secondary caused by movements of the cage is investigated. Furthermore, the effect of a reduction of the air gap as well as the influence of the end effects of the linear motor on the propulsion force are examined. The calculated propulsion force is compared to measurements taken from a model of the hoisting system
