• Encoder Resolves to within 5 arc-sec
  the signals outside, there is no concern about susceptibility to noise and EMI. The Dignalizer supports most major bus system outputs, including SSI, CANopen, DeviceNet, and Profibus, as well as RS-485 outputs. It offers both cable and radial-connector configurations and has 12-mm hollow-shaft...
• Getting the right angle
  . In the second category are angle encoders with an integral bearing, solid shaft, and separate shaft coupling. The shaft coupling compensates if the drive-shaft bearing experiences axial and radial run-out to the encoder shaft. But the two mating shafts must be optimally aligned to ensure accurate measurements...
• Focused FEA lets designers run fatigue analysis
  for simulation. "We spent too much time cleaning geometry and creating meshes," says Khosrow Namdarian, an analyst with the manufacturer. "Then it took at least a day to run a simulation on one design," he adds. MSC.Nastran provided rotary and radial wheel loading tests, and MSC.Fatigue simulated...
• PM DC Motors
  conventional unit. The typical range of torque for both brush-type and brushless dc motors is from 7.0 oz-in. to 4,500 lb-ft. Rare-earth magnets have little rotor inertia because they are light and have small radial dimensions. Flux density is also high. The torque-to-inertia ratio for rare-earth...
• Better inspection: Less Scrap
  Smart laser sensors spy tiny defects in tires before they roll off the assembly line. Smart laser sensors are used in tire production to monitor such metrics as thickness profile, splice width, radial runout, and sidewall integrity. A change in surface height DZ causes the imaged spot to shift...
• Mighty motors
  hard drives. But now, large permanent-magnet motors weigh in at up to 7 tons. The actual motor design is a radial-flux construction, air or water cooled, with a permanent-magnet rotor. Powers range from 22 to 670 hp (17 to 500 kW) and include base speeds from 220 to 600 rpm with voltages ranging...
• The "no-cog" motor
  or oscillations of rotational speed over time while torque ripple describes similar behavior in torque over time. Copper wires wound through the slots increase this effect. The unbalanced pull from tooth to tooth also produces a radial deflection in the rotor. Slotless BLDC motors overcome many iron-coremotor...
• Monitoring force ensures perfect joint
  results and lower costs with orbital forming. Sometimes referred to as spin or radial riveting, orbital forming most commonly serves to fasten an assembly by heading, crowning, swaging, flaring, or forming a column or projection of material. The process can replace fasteners such as screws, snap...
• Flexible gears minimize gearhead backlash for life
  on the design comes from HD Systems Inc., Hauppauge, N.Y. It's new Harmonic Planetary gearheads use a flexible ring gear as a "backlash buffer" to maintain backlash at out-of-box levels. The ring gear is made thinner in the radial direction than a typical ring gear so it can flex radially yet remain torsionally...
• Reverse engineering 101
  a standard shape from a menu, measure several points, and let the software complete the shape. Nonprismatic shapes can be digitized freehand, or by using one of several "locked-plane" scan techniques in which a part is traced and the software sections the trace as parallel planes, radial sections...
