Electromagnetic Model of Linear Resonant Actuators

Journal of Dynamic Systems, Measurement, and Control, 2023
AbstractLinear resonant actuators (LRAs) are used extensively in consumer electronic devices such as cell phones and fitness trackers to provide haptic signals to users. This work presents a dynamic model of LRAs based, principally, on the electromagnetic aspects of the these devices.

A flexure-based electromagnetic linear actuator

Nanotechnology, 2008
This paper introduces a novel nano-positioning actuator with large displacement and driving force, termed a flexure-based electromagnetic linear actuator (FELA). It mainly comprises an electromagnetic driving scheme and flexure-supporting bearings that provide infinite positioning resolution and highly repeatable motion.

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, 2009
The 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.

Position estimation for linear electromagnetic actuators

2017 IEEE International Symposium on Sensorless Control for Electrical Drives (SLED), 2017
This paper explores the possibilities of position estimation for linear electromagnetic actuators, in comparison to rotating electric motors. The linear actuator under study is a DC type short stroke permanent magnet actuator with an E-core stator. The non-linearity in the inductance model is first measured and identified on a commercially available ...

Loss analysis of electromagnetic linear actuator

International Journal of Applied Electromagnetics and Mechanics, 2014
This paper presents the research on loss analysis of the electromagnetic linear actuator (ELA) with the purpose of performance improvement of ELA applied to the engine electromagnetic driven valve train(EDVT). To define ELA's loss distribution and variation, quantitative analysis has been carried out against ELA's loss composition and variation at ...
