Shape optimization of electromagnetic actuators

2014 ELEKTRO, 2014
Shape optimization of the plunger of an electromagnetic actuator is carried out in order to obtain linear static characteristic of the device. The distribution of magnetic field in the system is modelled by a higher-order finite element technique using an effective implementation of the Newton method.

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.

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.

Dynamic behaviour of electromagnetic actuators

European Transactions on Electrical Power, 1991
AbstractThis paper describes a numerical method of calculating the dynamic behaviour of electromagnetic actuators supplied by a voltage of any waveform. Moving parts, eddy currents caused by the time variable field and the relative velocity to the field as well as saturation of the magnetic circle are taken into account.

DEVICE WITH AN ELECTROMAGNETIC ACTUATOR

2000
The invention relates to a device with an electromagnetic actuator for actuating a control unit that can be displaced in a longitudinal direction. The inventive device comprises at least one electromagnet which directly or indirectly acts upon the control unit. The position of the control unit can be measured by means of a first separate measuring coil

Ferrofluid-Based Soft Electromagnetic Actuator

This paper explores the feasibility of using soft electromagnetic actuators incorporating ferrofluids as the primary mechanism for generating tactile feedback in wearable haptic interfaces. The distinctive feature of this research is the utilization of ferrofluid as a dynamic, adaptable medium, manipulated by electromagnetic fields to simulate tactile ...
