• Prime-ratio steppers
  performance. The number of teeth on a nonprime-ratio stepmotor is relative to a 7.2° pitch for each tooth. The face of the stator pole should be as wide as possible to direct as much flux as possible into the air gap. More flux in the air gap produces greater torque and less heat due to more efficient...
• P/M Materials for Gear Applications
  a promising potential for a high performance/cost ratio. P/M Materials for Gear Applications P/M Materials for Gear Applications. Senad Dizdar and Pernilla Johansson, Höganäs AB, 263 83 Höganäs, Sweden. Abstract. P/M materials for gear applications have been reviewed based on results of own...
• Solid structures for machining centers
  . Radial displacement represents machine compliance at different angles. Because the models are symmetrical relative to the X-Z plane, considering only stiffnesses-from 0 to 180 relative to the positive X axis is sufficient. (Results for all three machines are presented in VMC compliance...
• Dryer clothing
  the cylinder temperature. On the contrary, a higher feed air temperature and greater exhaust air quantity in the first 3 groups would have a more favourable effect on the drying capacity. A change in the air temperature (dry) in the drying section by only 1oC, could change the relative humidity by up...
• A better way to Simulate Gaskets
  these hurdles by including several elements and material options to simulate gaskets. New elements let users directly measure relative deformation of the gasket's top and bottom surfaces. Users also can define pressureclosure characteristics to model gaskets' throughthickness behavior. At present...
• PLASTICS REFERENCE GUIDE
  made from the concentrates. Company president Barry Schwartz says that a resin-to-concentrate ratio of 25:1 gave an extrusion color match that was highly reproducible. Complex geometries yield the most dramatic effects, he notes, especially those with multiple curves, recesses, and sharp angles...
• Rugged Bearings Hold the Weight of Heavy Equipment
  , and rotates relative to the inner cylinder, the shaft. Any mechanism that removes sleeve-bearing material from between those cylindrical surfaces shortens bearing life. Harder materials or contaminants can abrade the surface. High spots can weld together, then break apart, producing adhesive wear...
• Joint decisions
  onetenth to one-third of total installed cost. Perhaps a better approach is to select fastening and joining methods by a process of elimination, not from the refining of "established" methods. A software screening utility from does just that. It looks at joint metrics including permanence, relative...
• Motor Follower - Electronic Gearing
  Encoder tracking is a technique that monitors a reference motor with an encoder and controls a secondary motor. The method provides programmable motor-to-encoder ratios that determine relative speed between two axes. A dynamic change in ratio produces acceleration or deceleration. Absolute...
• Fundamentals Of Ultrasonic plastic welding
  plastic-welding machines that feature calibrated amplitude and force. Exposure is set by the weld method and is the factor that turns off the power module. The four standard weld methods are: time, energy, relative distance, and absolute distance. Of course, various manufacturers of ultrasonic...
