Design and Multi‐Objective Optimisation of Double‐Sided Flux‐Concentrating and Stacked‐Winding Permanent Magnet Linear Motor

open access: yesIET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
In this paper, a variety of primary‐excited permanent magnet linear motors (PMLMs) are analysed and compared and a double‐sided flux‐concentrating slot permanent magnet linear motor (DFS‐PMLM) is proposed. The structural parameters of the proposed motor are optimised.
