HERCULES Series brushless linear servomotors are moving coils based on iron-less principle, zero cogging. The motors can be driven in sine-wave or six-step mode and have built-in cooling to operate with the same efficiency as motors that are air- or water-cooled, without hoses. They have a continuous force up to 38 lbs. Operation is available in two- or three-wire configuration including commutation. A range of forces and voltages are offered and matching amplifiers are available.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
