• Inside the frame
  Controller chips intelligent enough to handle most dc brushless power-management tasks can now sit within the motor frame itself. The result: Compact motor/driver packages with relatively few external connections. Circuit boards holding driver electronics can be designed in the same circular form...
• Distribute and conquer: Ethernet tackles motion control
  The DMC-3425 from Galil Motion Control Inc., Rocklin, Calif., the first controller in its E-Series, is a two-axis, Ethernetbased motion controller. It provides precise control of servomotors and includes both linear and circular interpolation algorithms in addition to PID filtering with notch...
• "What dreams may come"
  the suspended (front-center console-mounted) seats and free-hovering dashboard with Center Speedo — a revolving, circular digital/analog display. The digital side displays navi-system information. At the press of a button, the Center Speedo turns 180° to display water and engine-oil temp, as well as oil...
• Wired 9.08: Beam On
  of reflective gallium arsenide and gallium aluminum arsenide. Both are manufactured in a similar manner to microprocessors - 4-inch circular wafers are sliced into thousands of individual chips as small as 10 microns across. But each laser produces significantly different kinds of beams. The surface emitters...
• Digital Signal Processors "Think" Analog But Work Digitally
  . Special registers within the DSP hold beginning and ending addresses for buffer areas in DSP memory. Because the address does not have to be computed each time, it's faster accessing sequential data from memory buffers. Circular addressing automatically wraps the buffer pointer to the beginning...
• Making the move to PC-based motion control
  controller features. Controllers generate several types of motion profiles including point-to-point, linear/circular interpolation, and contouring. Point-to-point motion is the most basic type of controlled motion. As the name implies, an axis is made to move from one position to another. Point-to-point...
• The "no-cog" motor
  heat. Copper occupies only half of the winding space and so creates a large magnetic gap. The large gap limits magnetic-flux density and, thus, motor torque. In addition, the wide air gap between stator and rotor further reduces overall magnetic-flux density. The copper packing density of circular...
• Indicators
  doped with a conventional vapor-phase process. When used with a GaP substrate, an extremely bright device results. When these LEDs are coupled with an antireflection, circular-polarized filter, they provide sufficient luminous contrast to meet military requirements for sunlight readability...

  and manufacturing processes. The large variety of mountings adapt easily to different mechanical components or machine configurations. A flange mount is the most common form used with gear-boxes. Flange-mount motors, like many motors that mount directly to machinery, have a raised circular surface...
