Multi-Objective Optimization of Double Primary Tubular Permanent Magnet Synchronous Linear Motor in Wide Temperature Range Environment Based on Pareto Front Method

Abstract: In order to improve the thrust density of the electric actuator in aircraft, a double primary tubular permanent magnet synchronous linear motor is designed. By establishing the magnetic circuit model, the air gap magnetic density and thrust characteristics of outer and inner primary motors are analyzed. Considering that it works in the wide temperature range environment, a multi-objective optimization of motor is carried out. The surrogate model established by neural network is used to simplify the mathematica… Show more

“…Compared with double-sided flat linear machines, doublesided tubular machines (DSTM) eliminate the transverse end effect, and have higher energy density [1], [2] and higher application potential in the applications of high-end manufacturing equipment and wave energy conversion systems [3], [4]. Whereas, the cogging force caused by two slotted stators and the harmonic current in the armatures also lead to bigger noise and vibration [5].…”
