  • How to choose between round shafts or square profile rails
    The criteria for choosing one over the other are no different than choosing any other machine component: define system objectives, then consider factors such as load capacity, stiffness, accuracy, smoothness, size, and overall costs. The best place to start is to look at the fundamental qualities of
  • Steel Weights
    This calculator allows you to determine the approximate weight of your raw material using the density factor for the metal family selected and the dimensions of the shape (round bar, flat bar, square bar, hex bar, octagon bar, sheet, strip, plate, pipe, tubing, wire, rings, hubs, discs, shafts
  • Noise Suppression of Differential Signals
    An encoder is an electro-mechanical transducer that converts mechanical rotary motion into digital. signals for the control of machinery. The encoder produces a square wave signal as the shaft rotates. Speed, position, servo feedback, etc., can be determined through proper processing of this signal
  • Introduction
    at a given instant of time.2 This is far from a rigorous definition, but it suffices for the purposes of this introduction. For example, the states of a motor might include the currents through the windings, and the position and speed of the motor shaft. The states of an orbiting satellite might
  • Fixed Limit Gages...What Are They?
    . It follows that large numbers of shafts and bearings, screws and nuts and other assorted parts may be stockpiled at the assembly plant without having been test-fitted. If it is now possible to select parts at random and fit them into a functioning assembly, it is only because gages existed
