Thrust Ripple Analysis and Precise Modeling of 12/13 Slot-Pole Linear Flux-Switching Permanent Magnet Motors

open access: yesCES Transactions on Electrical Machines and Systems
Linear flux-switching permanent magnet motors (LFSPMs) have been proposed for long stator applications such as rail transit. However, the conventional linear permanent magnet synchronous motor (LPMSM) suffers from thrust ripple, which degrades the motor ...

A new design approach for reduction of force ripple in permanent magnet flux‐switching linear motor

open access: yesIET Electric Power Applications, 2023
To reduce the force ripple of the permanent magnet flux‐switching linear motor (PMFSLM), a new design approach is suggested by the authors. The detent force is redefined as the composite force of the thrust of the single action of permanent magnet and ...

A six-phase transverse-flux-reversal linear machine for low-speed reciprocating power generation [PDF]

open access: yes, 2015
In this paper, a 6-phase permanent-magnet flux-reversal linear machine for low-speed reciprocating power generation is presented. By increasing the phase number, the phase current is reduced for the same rated power which results in a lower ohmic loss ...
