We see from your search that you're looking for information on the term "Resolver",
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 Drives provide a smooth ride from
Control Techniques, which we summarised at the time by saying "The secure disable feature ensures when the secure disable input is disconnected, the drive will not operate the motor, even if combinations of components within the drive have
failed".
Earlier in the week,
we featured the news release Test rigs upgrade motor repair services from
Anstee Ware Group: "Permanent magnet motor repair and calibration service covers all manufacturers, makes and sizes, and includes the complete overhaul of motors, gearboxes and pumps".
In February 2008, we covered the news from Lenze
concerning its PositionServo
- take a look at Small drives suit external motion control
which says: "There are two ranges of matched synchronous servomotors available for PositionServo, offering a wide range of speeds and inertias".
Take a look also at the news release from Control Techniques, DaimlerChrysler places large drive order,
as well as Servos shrink to smaller square frames from Baldor UK,
and Low-profile connectors link small servos from ITT Electronic Components.
