Speed Control of Linear Induction Motor with Thrust and Stator Flux Ripple Reduction

2018 21st International Conference on Electrical Machines and Systems (ICEMS), 2018
This paper introduces a speed control of linear induction motor (LIM) by using three different strategies of control. A proportional Integral (PI) controller is used to control the speed of LIM. The output of the PI controller is regarded as the reference thrust for all three different schemes.

Thrust Ripple Reduction in Ultrahigh-Acceleration Moving-Permanent-Magnet Linear Synchronous Motor

IEEE Transactions on Magnetics, 2012
This paper describes thrust ripple reduction in an ultrahigh-acceleration moving-permanent-magnet linear synchronous motor (MPM LSM). The pole pitch of the permanent magnet (PM) is adjusted to reduce thrust ripple because this technique is effective and is easily applicable for many design procedures of PM LSMs.

Electromagnetic fields and thrust-ripples calculation for segmented-secondary linear flux-switching motors

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2019
Purpose This paper aims to investigate analytical electromagnetic fields and thrust ripples representation of linear flux-switching motors with simple modulated secondary referred as segmented secondary linear flux-switching motor (SSLFSM). Design/methodology/approach SSLFSMs are applicable to transportation systems like Maglev due to their simple ...

Thrust ripple analysis and suppression of a dual-PM transverse flux linear machine

International Journal of Applied Electromagnetics and Mechanics
Linear machines with high thrust force and low thrust ripple are essential for linear direct-drive applications. The transverse flux machines gain the advantage of high force density by decoupling of electric and magnetic loadings. However, there exists high thrust ripple defecting its performance.
