Design of high-speed linear induction motors– part II: end effect reduction
Design of high-speed linear induction motors– part II: end effect reduction
Traditional linear induction machines (LIMs) show a significant reduction of thrust as the speed of the machine increases, which is known as the end effect. This paper presents a comprehensive analysis of end effect in LIMs and its relationship with the magnetic Reynolds number (Rem). The relationship between end effect, Rem and the type of electrodynamic regime (resistance limited or inductance limited induced currents) is analyzed in detail. It is shown that reducing Rem, by increasing the reaction plate’s resistivity, reduces the end effect, resulting in marginal reduction of thrust in the high speed region. The paper presents a case study comparing a conventional LIM with respect to the proposed LIM with the appropriate reaction plate to reduce end effect, to illustrates the advantage of the latter in terms of thrust at high speeds.

Abstract
Traditional linear induction machines (LIMs) show a significant reduction of thrust as the speed of the machine increases, which is known as the end effect. This paper presents a comprehensive analysis of end effect in LIMs and its relationship with the magnetic Reynolds number (Rem). The relationship between end effect, Rem and the type of electrodynamic regime (resistance limited or inductance limited induced currents) is analyzed in detail. It is shown that reducing Rem, by increasing the reaction plate’s resistivity, reduces the end effect, resulting in marginal reduction of thrust in the high speed region. The paper presents a case study comparing a conventional LIM with respect to the proposed LIM with the appropriate reaction plate to reduce end effect, to illustrates the advantage of the latter in terms of thrust at high speeds.
