Analysis of the reduction of detent force in a permanent magnet linear synchronous motor

IEEE Transactions on Magnetics, 1995
The problem in improving the positioning precision of a permanent magnet linear synchronous motor (LSM) is the large detent force caused by the permanent magnet. The detent force is thought to arise from the difference of the position of a permanent magnet end and a tooth position.

Control-Based Reduction of Detent Force for Permanent Magnet Linear Synchronous Motor

IEEE Transactions on Magnetics, 2009
The detent force of the permanent magnet linear synchronous motor (PMLSM) is caused by the interaction between the permanent magnet and the iron core of the mover without input current. It is a function of the mover position relative to the stator. This paper proposes a control based method to reduce the detent force for the PMLSM.

Investigation of Auxiliary Poles Design Criteria on Reduction of End Effect of Detent Force for PMLSM

IEEE Transactions on Magnetics, 2009
The detent force in permanent magnet linear synchronous motor (PMLSM) is caused by the attraction between the permanent magnet (PM) and the iron core without input current. It can be divided into two components: the slot effect and the end effect. This paper proposes a novel technique to reduce the end effect of detent force using auxiliary poles.

A New Method for Reduction of Detent Force in Permanent Magnet Flux-Switching Linear Motors

IEEE Transactions on Magnetics, 2009
The permanent magnet (PM) flux-switching linear motor, which is developed from the PM flux-switching rotary machine, possesses similar advantages such as high power density and simple structure. Furthermore, the PM flux-switching linear motor has a potential for mass production at low cost, since the expensive coils and magnets are both set on the ...

Design criteria for detent force reduction of permanent-magnet linear synchronous motors with Halbach array

IEEE Transactions on Magnetics, 2002
Summary form only given. This paper presents the design criteria for the detent force reduction of the permanent magnet linear synchronous motor (PMLSM) with Halbach array. There are three approaches to improve the power efficiency of short PM pole-type LSMs: (1) the comparison of the magnetic field and forces of two types of PMLSM-a PMLSM with a ...
