We see from your search that you're looking for information on the term "Electric Actuator",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Actuators stand the test of reliability from
SMAC Europe, which we summarised at the time by saying "Electric actuators replace pneumatics in QC and switch test applications thanks to the high degree of precise force control and programmability".
A few weeks before,
we featured the news release Company offers new actuator options from
Orange Instruments: "Orange Instruments positioners use analogue signal conversion, comparison of desired and actual position and the operation of the actuator drive to bring the actuator to a stable position".
In February 2007, we covered the news from Micromech
concerning its Delta Tau UMAC controller
- take a look at Motion controller enables nano-level machining
which says: "A recent university project aimed to develop a machine tool capable of attaining 50nm accuracy with staggering 5nm repeatability".
Take a look also at the news release from Rotork Exeeco, British Energy receives actuator training rig,
as well as Sampling valve returns to safe position from Waters Equipment,
and France comes onboard from Rotork Controls.
