Development of linear actuator for electromagnetic pump

International Journal of Applied Electromagnetics and Mechanics, 2019
Recently, the majority of artificial hearts have been non-pulsatile types. However natural hearts are pulsatile, and the long-term bio-compatibility of the non-pulsatile types has not been confirmed. We developed a linear actuator that can expect to be applied to pulsatile artificial heart.

The PemRam - an electromagnetic linear actuator

IEE Colloquium on Actuator Technology: Current Practice and New Developments, 1996
The PemRam was originally designed to replace hydraulics in vehicle simulators. Previously, only high-pressure fluid actuators could provide the bandwidth and precision that was needed for accurate motion simulation but they could not be used in confined spaces close to the general public.

Electromagnetic linear actuators with inductive position sensing

Sensors and Actuators A: Physical, 1996
Abstract Magnetically driven linear micro-actuators with 1 mN output force and hundreds of microns of total travel have been realized using LIGA-like processing techniques. These devices are driven at resonance frequencies of around 350 Hz and exhibit quality factors of about 300 in air.

Linear Electromagnetic Actuators and Their Control: A Review

EPE Journal, 2004
Linear electromagnetic actuators develop directly thrust and thus linear motion. In principle rotary motion electromagnetic motors may be turned into their linear counterparts by cutting them axial...

Robust electromagnetic optimization of linear tubular actuators

IEEE Transactions on Magnetics, 2004
The concept of robust optimization of electromagnetic devices using finite-element models is presented. An original "trellis" experimental design is used to achieve the optimization process and a robustness analysis is done using the signal-to-noise ratio. The robustness study deals with modeling and building noises and is applied to the optimal design

Automobile Suspensions Using Electromagnetic Linear Actuators

IFAC Proceedings Volumes, 2000
Abstract The development of rare-earth magnetic materials, power electronics and control has enabled the construction of lighter and smaller permanent magnet actuators. Its reduced friction losses and the natural control flexibility of the electric equipment should allow for improvements in the automobile suspension behaviour.

Design and Modelling of a Novel Linear Electromagnetic Actuator

IFAC Proceedings Volumes, 2004
Abstract 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
