A miniature short stroke linear actuator - Design and analysis [PDF]

open access: yes, 2008
We report a newly developed miniature short stroke tubular linear permanent-magnet actuator for robotic applications. Compared to a rotary-to-linear mechanism, the linear actuator has the advantages of efficiency, thrust control, and compact size in ...

Multiobjective analysis for the design and control of an electromagnetic valve actuator [PDF]

open access: yes, 2007
The electromagnetic valve actuator can deliver much improved fuel efficiency and reduced emissions in spark ignition (SI) engines owing to the potential for variable valve timing when compared with cam-operated, or conventional, variable valve strategies.

On force generation in electro-fluidic linear actuators with ferrofluid

open access: yesScientific Reports, 2022
In ferrofluid actuation systems, forces are generated by actively controlling pressure and flow within the fluid using an applied magnetic field. There are multiple contributing factors in force generation involving complex non-linear couplings between ...
