Electromagnetic actuator for voice coil

The Journal of the Acoustical Society of America, 1979
An electromagnetic actuator for linear driving of movable heads of a magnetic disc unit in an information processing system. A plurality of slits or plates are provided with a magnetic pole inscribed directly on the internal surface of a permanent magnet, and increase magnetic reluctance of the magnetic path and reduce inductance of a moving coil, thus

Case study of an electromagnetic actuator

2016 17th International Carpathian Control Conference (ICCC), 2016
The paper proposes both a behavioral model of the electromagnetic actuator and experimental results. An electromagnetic actuator structure is a system composed from coils and permanent magnets is presented. The electromagnetic actuators are used as: themselves for producing mechanical displacement and/or force generation, driving element for hydraulic ...

Network models of electromagnetic actuators

15th International Workshop on Research and Education in Mechatronics (REM), 2014
The paper presents network models that are used in the analysis and design of electromagnetic actuators. The attention is focused on the magnetic networks. Both permeance and reluctance networks are analyzed. The presented network models are formed using the finite element methods.

Numerical calculation of electromagnetic actuators

Archiv für Elektrotechnik, 1979
The paper describes a numerical method of calculating the magnetic fields, forces, inductances, and the dynamic behaviour of electromagnetic actuators. The solution of the non-linear partial differential equation for the magnetic vector potential is obtained by finite difference techniques using line iteration and acceleration of convergence.

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 actuation in MEMS switches

2015
Power electronics takes use of switches in order to convert and manage energy. The ideal switch with low power loss consists of electromechanic relays, but since they are bulky and expensive, semiconductors switches are more widely used for power electronic applications, resulting in power losses during energy conversion.
