OPTIMAL DESIGN OF EQUIVALENT LINEAR INDUCTION MOTOR BASED ON HARMONY SEARCH ALGORITHM AND ANALYSIS USING FINITE ELEMENT METHOD

Abstract

Linear Induction motors (LIM) are used extensively in industrial applications to develop linear motion, especially in transportation systems. These applications need high efficiency with high power factor. Mainly LIM suffer from two major drawbacks, low power factor and low efficiency. These drawbacks cause highenergy consumption and high input current. In this paper, a novel multi objective Harmony Search optimization algorithm (HSA) is proposed to meet required efficiency and power factor in the design of a Linear Induction Motor. Hence, LIM dimensions can then be optimized by using a HSA in an appropriate objective functions. 2-D Finite Element Method is adopted to analyse the flux density in LIM with the parameters obtained using HSA.
