Abstract

This article analyzes the flux characteristics of a novel tubular permanent magnet linear launcher (TPMLL) with short stroke and high-frequency motion characteristics, suitable for application in the electromagnetic launcher. In this article, the proposed TPMLL consists of the following parts: the outer stator, outer air gap, mover made of permanent magnets (PMs), inner air gap, and the inner stator. A magnetic equivalent circuit (MEC) method is established to analyze the electromagnetic characteristics and provide the basis for the structural design. To solve the MEC model, the Newton–Raphson method is adopted. By comparing the results of the finite element method (FEM) with the MEC model, it is found that the accuracy of MEC method has good accuracy in estimating the flux linkage of the proposed motor, which is very suitable to be used in the initial stage of the structural design.
