Analytical Modeling of Novel High Thrust Force Density Segmented PM Consequent Pole Linear Flux Switching Machine

IEEE Access, 2022
Permanent Magnet Linear Flux Switching Machines (PMLFSMs) are potential candidates when higher thrust force ( $\boldsymbol {T}_{ \boldsymbol {F}}$ ) and low cost are the primal requirements.

Few‐sample multi‐objective optimisation of a double‐sided tubular machine with hybrid segmented permanent magnet

IET Electric Power Applications, 2022
Double‐sided tubular machine (DSTM) is very suitable for wave energy conversion but easily suffers from high thrust ripple. In order to get the minimum cogging force with the maximum thrust force, a new DSTM with hybrid segmented permanent magnet array ...

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

CES 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 ...

An Innovative H-Type Flux Switching Permanent Magnet Linear Generator for Thrust Force Enhancement

Energies, 2023
In this paper, two H-type flux switching permanent magnet linear generators with outer-translator and inner-translator configurations are discussed and compared to a more conventional flux switching topology. The stators consist of H-Type modules housing

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object

Advanced Engineering Materials, EarlyView.
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐
