A RBFN Based Cogging Force Estimator of PMLSM with q<1 Structure
2006The cogging force has great impact to the efficiency of permanent magnetic liner synchronous motor (PMLSM) especially at high precision and low speed. This paper presents a cogging force estimator based on radical basis functional network (RBFN) by accelerated fuzzy c-means algorithm. Comparing to the estimator based on back propagation neural network (

Reduction of cogging force in an electromechanical transducer powering an MR linear damper
Proceedings of the 14th International Carpathian Control Conference (ICCC), 2013An electromechanical transducer and a linear MR damper powered by the transducer are the key components of a smart MR damper device with power generation. A cogging force, inherent in all ferromagnetic-permanent magnet systems, will also arise in the transducer. Its occurrence negatively impacts on the transducer performance, and hence efforts are made

An approach to reduce the cogging force in tubular linear PM synchronous machines
2015 Tenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2015The paper is aimed at an approach to reduce the cogging force in tubular linear permanent magnet synchronous machines (T-LPMSMs). An analytic prediction of the air gap flux density distribution is developed in a first step, considering the case of slottless machine and the case where the slotting effect is taken into consideration.

Cogging force reduction of two-phase linear hybrid stepping motor
IEEE Transactions on Magnetics, 2005This paper presents a /spl pi//4-multiple-coupled two-phase linear hybrid stepping motor (LHSM) that has two windings per phase, one of which shares the other phase winding. The proposed motor shows a unique ability to deliver low cogging force without any complex control scheme or additional power electronics hardware in microstepping control.

Quantitative feedback control of a linear positioning stage with cogging force compensation
2008 3rd IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2008Quantitative feedback control of a linear positioning stage with cogging force compensation is presented. Positioning stage direct-driven by linear motors commonly suffers from significant mechanical resonances at high acceleration rates. Which is solved by using a tracking control scheme based quantitative feedback theory (QFT).

Loss analysis for the hybrid linear switched reluctance motor with no cogging force
2015 IEEE Magnetics Conference (INTERMAG), 2015Linear motors are suitable for direct-drive applications in industry. To improve the performance of pure linear switched reluctance motors (LSRMs), permanent magnets (PMs) are introduced to the magnetic circuits [1-3]. Loss of the PM-type linear motors are discussed [2]. Two possible ways of cogging force reduction are investigated [3].
