We see from your search that you're looking for information on the term "Resolvers",
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 Servo drives combine reliability and flexibility from
Control Techniques, which we summarised at the time by saying "The Digitax ST range has been designed to provide lean manufacturing environments with smaller, more flexible machinery".
A few weeks before,
we featured the news release Servo motors squeeze power into a small package from
Micromech: "AKM motors come in seven standard flange sizes of 40 to 188mm, with different flange/pitch circle versions available on request".
In October 2007, we covered the news from Hayes Control Systems
concerning its AM3500 low-inertia servomotors
- take a look at Low-inertia servomotors suit high dynamic motion
which says: "AM3500 motors are particularly suitable for highly dynamic applications with high loads, for machine tool axes or gearless applications".
Take a look also at the news release from Lenze, Geared servomotors offer large torque range,
as well as Servo motors handle a range of applications from Control Techniques,
and Resolver feedback support added to servo drives from Parker Hannifin Electromechanical Automation.
