Comparison of rare‐earth and hybrid‐magnet mover configurations for a permanent magnet synchronous linear motor

IET Electric Power Applications, Volume 15, Issue 3, Page 321-331, March 2021., 2021
Abstract Force ripple and cost reduction are two of the main challenges in optimising the design and increasing the market uptake of permanent magnet synchronous linear motors (PMSLM). Two mover configurations are compared in depth; one made entirely from rare‐earth materials while another consisting of a hybrid (rare‐earth/ferrite) magnet layout ...
