"Air" on the side of smoothness
, air bearings offer less resistance (friction) to steady-state motion. Friction generates heat which, in turn, causes spindles and other components to thermally grow, compromising precision. Air bearings generate much less heat in a given application than rolling-element or plain bearings in most

Motor Eliminates Cogging Torque for Ultra Smooth Servo Track Writer
Air bearing spindles for such demanding and close-tolerance applications as wafer Manufacturing and handling equipment and servo writers require especially smooth velocity. Typically, we use an 8-pole slotted brushless DC (BLDC) motor in these applications. However, for a recent servo writer

Limited-Angle Torque Motors
power spindles in hard-disk drives, in certain high-speed air-conditioning and ventilation systems, and in other equipment calling for a high inertia. The high inertia makes possible very precise speed regulation. Applications calling for high torque and low speed need brushless motors having a large

The attraction of Ferrofluid Bearings
periodic maintenance. Air bearings as well have negligible nonrepetitive runout. And they operate with low friction. But the low viscosity of air necessitates bearing clearances on the order of a few microns and large bearing diameters. In addition, bearing surfaces must contain highly precise, shallow

Ain't that America
For over a decade, Ford Motor Co.'s Special Vehicle Team (SVT) has kept America's love for high-performance vehicles alive. A midengine configuration carries an aluminum engine cradle behind the bulkhead that holds the 500-hp V8. SVT engineers had a hand in the creation of the GT40 concept
