  • Motor Pulley Selection Chart
    Frequently questions arise concerning the selection of the proper motor pulley to get the required. pump performance. Here are charts which show the available motor pulley sizes with the respective pump RPM that. each motor pulley will deliver as well as the total pump output in G.P.M.
  • Stepper Motor Closes The Loop Around Tough Moves
    Positioning is central to a wide range of industrial applications, from the placement of electronic com-ponents on a printed-circuit board to labeling and packaging operations. AlphaStep motors with planetary gearheads are available in six gear ratios from 5:1 to 50:1. An optional electromagnetic
  • How to Acquire the Best Application Advantage
    At the dawn of the industrial age, the predominant. machine was the AC induction motor, which is basically. a constant speed device. Thus when applications. required different speeds, the pulley would be changed, resulting in significant production downtime - it took a long time to change pulleys.
  • A Finer Control of Linear Motion
    force and motion through a straight line. In a typical mechanical system, a device's output shaft would provide linear motion using a rotary motor through gears, a belt and pulley, or other mechanical components. Trouble is, these components must be coupled and aligned. Worse yet, they add wear
  • A Change in Speed Control Strategy Ramps up Production for Steel Company
    of worn-out parts, and was out of service for repairs too often. The thread roller had variable sheave pulley speed controls, which were the source of numerous problems due to a preponderance of moving parts. The controls also required constant operator interaction to change speeds and make other
  • How to make bearings last in electric motors
    ruined when a motor is used improperly. For example, the deep-groove ball bearings optimized for in-line couplers can overload if motors fitted with them drive a belt pulley. Likewise, motors containing roller bearings for heavy belt loads may prematurely fail when run with an in-line coupler
  • Rolling-ring actuators spool up production, cut costs
    . No more. Jennings now offers take-up reels as an option with the machines. It chose for the traversing portion a rolling-ring linear actuator from Amacoil Inc., Aston, Pa. ( ). The rolling-ring design allows the use of a single, unidirectional motor to drive a simple pulley system. The pulleys

  • Dubbel
    The drive shaft in the bucket elevator head carries driving drum or drive rollers , drive chain wheels or working breed.
  • Dubbel
    The drive shaft at the bucket elevator head, the driving drum, drive rollers carry or drive wheels.
  • Vie path manual motor vehicle technology
    It can Umlenk- and tensioning rollers with the drive rollers of secondary aggregates interleaved to be arranged and the growing space at the motor to be filled so very compactly (. Abb. 5.26).
  • Handbook Timing Belts
    Multiple shaft drives, as shown in Fig. 2.14d, are usually driven from a motor pulley and the driven pulleys absorb parts of the power transmitted.
  • Identification of a Bipedal Robot with a Compliant Drivetrain
    First, to minimize the effect of friction from the remaining pulleys, each motor pulley is isolated by discon- necting the cable between the motor and the rest of the trans- mission.
  • A General-Purpose 7 DOF Haptic Device: Applications Toward Robot-Assisted Surgery
    The direct drive dc motor with encoder (manufactured by Maxon, Burlingame, CA) and motor pulley is attached to and mounted below the forearm rest to minimize interferences with the user’s arm.
  • Drive solutions
    Leads through the diameter d of the drive roller of the conveying distance from 350 mms this to a number of revolutions of 2,543 rad/s .
  • Transport and storage logistics
    Drive roller .
  • Drying performance of a tumbler dryer with condenser
    The volumetric flow rate of recirculation air was controlled by the diameter ratio of the motor pulley to the fan pulley at a given cycle speed of the motor.
