We see from your search that you're looking for information on the term "Linear Motor",
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 Ceramic actuators clean up on medical applications from
PI (Physik Instrumente), which we summarised at the time by saying "PI offers three advanced types of ceramic, nonmagnetic linear motor actuators that can replace classical actuators in medical and pharmaceutical applications".
A couple of weeks before,
we featured the news release Linear motion conference focuses on precision from
Renishaw: "The Linear Motion Masterclass will focus on how linear motion is moving into the realm of high accuracy and precision applications".
In December 2007, we covered the news from New Scale Technologies
concerning its SQL-1.8 Squiggle motor
- take a look at Tiny linear motor is faster and stronger
which says: "The tiny SQL-1.8 Squiggle motor travels as fast as 7mm/s and pushes axial loads of up to 30g - nearly 200 times its own weight of 0.16g".
Take a look also at the news release from LG Motion, Guideway provides quiet operation,
as well as Tiny linear motor tolerates harsh environments from Orlin Technologies,
and Linear motor catalogue covers wide range from PI (Physik Instrumente).
