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.

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 ...

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 ...

Analysis and Design of a Maglev Permanent Magnet Synchronous Linear Motor to Reduce Additional Torque in dq Current Control

Energies, 2018
The maglev linear motor has three degrees of motion freedom, which are respectively realized by the thrust force in the x-axis, the levitation force in the z-axis and the torque around the y-axis. Both the thrust force and levitation force can be seen as
