Dynamic optimization of an axisymmetric linear electromagnetic valve actuator
2013 Eighth International Conference and Exhibition on Ecological Vehicles and Renewable Energies (EVER), 2013The aim of this paper is to describe the optimization of a permanent magnet linear actuator with soft mover for electromagnetic valves. A 2D numerical model based on finite element method was applied for magnetic field analysis in the electromagnetic actuator.

Poly-optimization of coil in electromagnetic linear actuator
2007The main advantages of the electromagnetic linear actuators are the simple design structure, the fast response for input signal, a possibility to achieve a high linear acceleration and a low cost of maintenance [4][5]. Moreover, a linear motion is a natural output, so there is no need of any mechanical transmission.

Model Of The Electromagnetic Linear Actuator For Optimization Purposes
ECMS 2009 Proceedings edited by J. Otamendi, A. Bargiela, J. L. Montes, L. M. Doncel Pedrera, 2009The goal is to present a more accurate model for optimization of design and of a supply control. The object is an electromagnetic linear actuator which is built of series of coils and of a ferromagnetic moving core. The coils are supplied by time series of current impulses.

Design of a Normal Stress Electromagnetic Fast Linear Actuator
IEEE Transactions on Magnetics, 2010This paper describes the design of a normal stress electromagnetic linear actuator for fast tool servos during nonrotationally symmetric diamond turning. By using the permanent magnet as the biasing flux generator and the total armature pole surface for force generation, the actuator is designed to achieve both linear operation characteristics and high

Design and Modelling of a Novel Linear Electromagnetic Actuator
IFAC Proceedings Volumes, 2004Abstract The paper presents the design of a novel permanent magnet linear actuator for short-stroke and high dynamic operations. The design procedure based on the magnetic analysis is shown and finite-element calculation results are given. In the second part the modelling of the developed actuator for dynamic and control studies is presented, where a

Optimization of an Electromagnetic Linear Actuator Operating in Error Actuated Control System
2008In the paper an algorithm and computer software for the optimisation of error actuated control systems containing of an electromagnetic linear actuator is presented. The software consists of two main parts: (a) optimisation solver and (b) numerical model of the actuator. For the optimisation, the genetic algorithm (GA) has been used. The field discrete
