種々の二次導体板による片側式LIMの等価回路定数と特性の変化 Change of Equivalent Circuit Parameters and Performance Characteristics of Single-sided LIMs with Various Secondary Conducting Plates
This paper describes the equations for calculation of the equivalent secondary resistance and the equivalent secondary reactance referred to the primary of single-sided linear induction motor (SLIM) and shows the change of those equivalent circuit parameters and the operating characteristics with various secondary conducting plates.<br>Usually, a composite conductor slab which is consisted of an aluminum plate backed with a solid steel plate is used. In order to simplify the calculation, we have assumed that the back-iron plate consists of a laminated core instead of a solid steel core.<br>Firstly, the computed results of the performance characteristics of a SLIM with the secondary aluminum plate backed with either solid steel plate or laminated core are shown comparatively.<br>It was confirmed that the characteristics curves in the case of laminated core give close agreement with the curves in the case of solid steel:<br>In practice the reaction rail backed with a solid steel is better than that backed with a laminated core from the point of view of economy, robustness and corrosion.<br>Next, the calculated results of the performance characteristics of a SLIM with a single secondary aluminum plate or a single secondary iron plate are shown.
