  • Comparing Digital Potentiometers to Mechanical Potentiometers
    of these two devices are shown in Figure 1. resistive material has its own set of performance char-. Basics of Mechanical Potentiometers. acteristics. In this application note the digital potentiom-. eter will only be compared to the more popular cermet. The first type of potentiometer on the market
  • Selecting and Sizing Ball Screw Drives
    bearings, giving a comparatively low relative load. per bal . With rolling elements the bal screw drive has a very low friction coefficient. Ball. screw drives typically provide mechanical efficiency of greater than 90% so their higher. initial cost is often offset by reduced power requirements
  • Mechanical Transmission Requirements for Servo Systems
    . Notable Quotables. Press Releases. Wacky News of the World. Applied Motion Products, Inc. Nema 23 Step Motor - NEMA 23 Frame Stepper Motors. Mechanical Transmission Requirements For Servo Systems. - January, 2003. When reviewing the most common types of mechanical transmissions used with servo
  • Mechanical Torque Limiters Still Make Sense
    . Therefore some means of protection is a necessity, whether mechanical, electrical or a combination of both. Electrical and electronic protection typically fall into two main categories: sensors and controls. Sensing devices, such as current sensors, monitor one particular aspect of the drive
  • Kerk Lead Screws Help Diamong Analyzer Achieve Dazzling Accuracy (.pdf)
    to be very accurate in where the rail stops," explained Kurt Schoeckert, a. GemEx co-founder and a mechanical engineer who was instrumental in the design of the. BrillianceScope. "Because of its comparative scale, the diamond has to reside in the exact same. five spots every single time we run an analysis
  • Is Your Networking Device Tough Enough?
    effectiveness. Well-protected devices are likely to be sealed in single-piece or seamless casing and will favor membrane buttons over mechanical push-buttons. Vents or other openings will be avoided or minimized. Since water and dust protection are critical features for many applications, the industry
