Wired 7.11: Electric Word

The new National Ignition Facility at Lawrence Livermore National Lab ( ) could be described as a $1.5 billion game of thermonuclear laser tag. Thirty feet in diameter, NIF's spherical fusion chamber houses the world's largest laser, aiming 192 beams totaling 500 trillion watts of power at a BB-sized capsule containing hydrogen isotopes; the target quickly reaches the temperature and density of the sun's core or the center of an atomic explosion. Hot fusion's applications range from astrophysics to national defense. "This country doesn't do nuclear testing anymore," says NIF senior scientist Bill Hogan. "The facility lets us test the properties of a material in a thermonuclear state." Under the gun this fall for cost overruns, the project has already licensed NIF technologies to

Products & Services
Brushless Motors
Brushless motors are synchronous electric motors that have a magnetically (AC induction) or electronically (DC) controlled commutation system instead of a brush-based mechanical commutation system.
Gearmotors
Gearmotors consist of an AC or DC motor with an integral gearbox or gear head typically used to adjust the motor's output speed and torque.
AC Motors
AC motors include single, multiphase, universal, induction, synchronous, and gear motors. They also include servomotors.  
DC Motors
DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
Motor Speed Controllers
Motor speed controllers are electronic devices that control motor speed. They carry specifications for drive type, product classification, electrical ratings, and operating parameters.
