Haptic Mouse Interface Actuated by an Electromagnet
2011 International Conference on Complex, Intelligent, and Software Intensive Systems, 2011In this paper, we propose a hap tic feedback mouse that is actuated by an electromagnet. The hap tic mouse works like a normal optical mouse but attraction force is generated between the electromagnet and a ferromagnetic mouse pad. We introduce some examples using the hap tic mouse.

A flexure-based electromagnetic linear actuator
Nanotechnology, 2008This 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.

A new electromagnetic valve actuator
Power Electronics in Transportation, 2002, 2005In conventional internal combustion engines, engine valve displacements are fixed relative to crankshaft position. If these valves are actuated as a variable function of crankshaft angle, significant improvements in fuel economy can be achieved. Existing electromagnetically actuated variable-valve-timing (WT) systems characteristically use springs to ...

Planar multidipolar electromagnetic actuators
IEEE Transactions on Magnetics, 2003We have conducted a study to find the most powerful planar magnetic actuator that works with a limited amount of current. The actuator must be flat so that it can be fabricated with thin-film or thick-film techniques. In this paper, we propose several configurations of planar electromagnetic actuators.

Evaluation of electromagnetic actuator analysis
2006 37th IEEE Power Electronics Specialists Conference, 2006In this paper the three different level of co-simulation are compared and the output waveforms are presented. The co-simulation is realized between two different programs (power electronic circuit simulator — control part and finite element analysis — magnetic and mechanic model part).

DEVICE WITH AN ELECTROMAGNETIC ACTUATOR
2000The 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
