We see from your search that you're looking for information on the term "NEMA",
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 Three-phase stepper is a smooth runner from
Astrosyn International Technology, which we summarised at the time by saying "Three-phase layout enables the stepper motor to provide very quiet, smooth motion as well as high accuracy, with a step angle of 1.2 degrees".
A couple of weeks before,
we featured the news release Servo drives combine reliability and flexibility from
Control Techniques: "The Digitax ST range has been designed to provide lean manufacturing environments with smaller, more flexible machinery".
In January 2008, we covered the news from QuickSilver Controls
concerning its DMX512 serial protocol
- take a look at Servomotor controller receives new protocol
which says: "The DMX frame contains 512byte of data to control such things as lighting dimmers, fog machines and QuickSilver's servomotors".
Take a look also at the news release from AutomationDirect, Wire suits machine builders and installations,
as well as Tiny sensors boast longer ranges from Turck,
and Steppers solve wiring conundrum from McLennan Servo Supplies.
