Detent Force Reduction Design for the C-Core Single-Phase Permanent Magnet Linear Oscillation Actuator

2021 13th International Symposium on Linear Drives for Industry Applications (LDIA), 2021
Single-phase permanent magnet linear oscillation actuators (SP-PMLOA) have been paid extensive attention in the field of compressors and industry applications. However, the detent force of SP-PMLOA limits the effective stroke and affects the control accuracy of the system.

Methods of detent force reduction in linear synchronous motors

IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003
The 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

Detent force reduction in permanent-magnet linear synchronous motor utilizing auxiliary poles

2009 8th International Symposium on Advanced Electromechanical Motion Systems & Electric Drives Joint Symposium, 2009
This paper proposes a novel technique to reduce the detent force in permanent magnet linear synchronous motor (PMLSM) using auxiliary poles. 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.

Design strategy for detent force reduction of permanent magnet linear synchronous motor

Journal of Shanghai University (English Edition), 2008
The 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).

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.

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.

Reduction of detent force in permanent magnet linear synchronous motor with double secondary side

2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014
In view of that detent force (DF) has great influence on thrust force ripple of permanent magnet linear synchronous motor (PMLSM), magnet-shifting method is introduced to suppress DF and its spatial harmonic. A double-sided PMLSM model is chosen as the object of research, finite element method (FEM) is adopted to build PMLSM model and Fourier transform

Detent force reduction of permanent magnet linear synchronous motor by imposing auxiliary poles technique

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.

Detent Force Reduction in Permanent Magnet Tubular Linear Generator for Direct-Driver Wave Energy Conversion

IEEE Transactions on Magnetics, 2013
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 ...
