In this paper, a quasi-Halbach magnetization structure of permanent magnet tubular linear generator (PMTLG) with bulged stators and auxiliary slots is proposed to reduce the detent force. In the meantime, the detent force for the structure of 9 PM poles 10 winding slots and the conventional one of 8 PM poles 12 winding slots is compared by using ...

This paper analytically and experimentally shows effectiveness and simplicity of mover teeth arrangement design, which dramatically reduces detent force and consequently speed ripple at low speed. For this purpose, this paper describes two design steps that include the conventional magnetic circuit optimization by response surface methodology (RSM) and

A New Method for Reduction of Detent Force in Permanent Magnet Flux-Switching Linear Motors
IEEE Transactions on Magnetics, 2009The 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 ...

This study considers the reduction of the force ripple of a permanent magnet linear synchronous machine (PMLSM). The PMLSM has a relatively large magnetic air gap. Therefore, a slotted type of stator structure is generally employed. Furthermore, the detent force, which is caused by the energy imbalances owing to the interaction between the teeth-slot ...

Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation, 2010
This paper proposes a novel technique to reduce the detent force in permanent magnet linear synchronous motor (PMLSM) using auxiliary poles technique. The detent force that is caused by the attraction between permanent magnet (PM) and the iron core without input current can be divided into two components: the slot effect and the end effect.

Methods of detent force reduction in linear synchronous motors
IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003The thrust force characteristic of a permanent magnet linear synchronous motor consists of a combination of three independent forces. One of these forces, the detent force, has an adverse effect on the performance of a linear synchronous motor. There are various methods to reduce the detent force. Finite element methods are used to assess the different

Design strategy for detent force reduction of permanent magnet linear synchronous motor
Journal of Shanghai University (English Edition), 2008The detent force of a permanent magnet linear synchronous motor (PMLSM) is analyzed and the corresponding optimization methods are presented to reduce it. The detent force, which is divided into two components, i.e. resulting from the end effect and resulting from the slotting effect, can be analyzed respectively by the finite element method (FEM).
