Electromagnetically driven elastic actuator

2014 IEEE International Conference on Robotics and Biomimetics (ROBIO 2014), 2014
Elastic and active elements will play a leading role in the development of dexterous and compliant robots. We present the fabrication of an elastic functional structure with ferromagnetic properties capable of producing compressive stress and strain in the presence of magnetic fields.

Haptic Mouse Interface Actuated by an Electromagnet

2011 International Conference on Complex, Intelligent, and Software Intensive Systems, 2011
In 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, 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.

Analytical Force Determination in an Electromagnetic Actuator

IEEE Transactions on Magnetics, 2005
An original analytical determination of the force acting on the moving coil in an electromagnetic actuator is presented. The actuator magnetic field is solved analytically using the Schwarz-Christoffel (SC) mapping. The SC integral is solved analytically using the elliptic functions.

A new electromagnetic valve actuator

Power Electronics in Transportation, 2002, 2005
In 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, 2003
We 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, 2006
In 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).

Structure and Electromagnetic Actuation Systems of Microrobot

2012
According to the feature of the magnetic actuation principle, now there are mainly three driving methods: one is alternating magnetic field, another is stationary gradient magnetic field and the last one is rotating magnetic field. This paper provides a detailed insight into the present-day state of microrobot technology and development on structure ...

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
