Review of Linear Motor Topologies with Passive Secondaries and a Comparison to an Active Secondary Topology

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

This paper presents a literature overview of different linear motor topologies utilizing a passive secondary that can be considered for long stroke applications. Based on this review the Linear Flux-switching Machine is selected for further investigation: the disadvantages and the possible solutions proposed in literature are discussed. Furthermore, Finite Element Method models are created of the Linear Flux-switching Machine, together with the enhancements, for validation purposes. Based on the simulation results, it is concluded that the improvements of the Linear Flux-switching Machine reduce the force ripple by 77.9 % and the attraction force by 91.6 %. Finally, a performance comparison is made with a Linear Permanent Magnet Synchronous Machine utilizing an active secondary, which is selected as benchmark topology. The comparison demonstrates that the Linear Flux-switching Machine provides a cost-efficient alternative for long stroke applications where the design volume is not restricted.
