Optimum design of Maglev lift system's electromagnet for weight reduction using response surface methodology

Abstract

Purpose

This paper aims to discuss the optimum design of a Maglev lift system's electromagnet to reduce the weight of the machine with constraint of normal force using response surface methodology (RSM).

Design/methodology/approach

The optimum design of Maglev lift system's electromagnet for weight reduction is performed by using RSM. The magnetostatic analysis of Maglev lift system's electromagnet is performed by using ANSYS.

Findings

The process is based on minimization of an appropriate objective function, while at each step the response is determined by the 3D finite element method (FEM).

Research limitations/implications

It is necessary to compare normal force between the 3D FEM result and the experimental result of the manufactured model.

Originality/value

The paper deals with the possibility of using the RSM for optimization of an electromagnet with a higher number of the design variables.
