  • Replacing a Mechanical Adjustable Speed Drive with a Variable Speed Drive
    Retrofitting an application using a mechanical adjustable speed drive such as a Reeves Motodrive® to an AC or DC variable speed drive can be done successfully if all the details are understood beforehand. First, let's take a look at what a Motodrive really looks like conceptually. A constant speed
  • Variable-Pitch Drives
    Variable-pitch drives are the simplest of all mechanical adjustable-speed mechanisms. Most of these drives use rubber belts. However, chain types are unmatched in regard to its particular strong points. Belt and chain adjustable-speed drives are "adjustable " in two senses. One type
  • Gear Drives
    The most reliable means for changing shaft speed remains a mechanical variable-speed transmission. These drives are used to provide a variable output speed from a constant-speed power source (as in a machine tool driven by a constant-speed ac motor) or to provide torque increase
  • Hydrostatic Drives
    Hydrostatic drives are widely recognized as an excellent means of power transmission when variable output speed is required. Typically outperforming mechanical and electrical variable-speed drives and gear-type transmissions, they offer fast response, maintain precise speed under varying loads
  • Energy Efficiency Improvement with Permanent Magnet Motors and Variable-Frequency Drives
    In the induction motor, slip frequency (i.e., the frequency difference between stator rotating flux and mechanical rotating speed) induces current in the rotor windings. The interaction between rotating magnetic field and induced rotor current produces a driving force, but the motor current causes
  • Hydrokinetic
    variable-speed hydrokinetic couplings are equipped with heat exchangers. These drives are controlled by adjusting the amount of oil in the casing. Most scoop-tube controlled hydrokinetic drives use electrical, hydraulic, or pneumatic controllers, but a few drives are manually controlled. Because the drive
  • Rotary encoders for motors
    to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ac-induction motors are widely used mechanical power sources because of their inexpensive yet rugged construction. When coupled with variable
  • How VFDs Save Energy
    Variable frequency drives (VFD) are becoming more common place and more widely used in applications. They are capable of varying the output speed of a motor without the need for mechanical pulleys, thus reducing the number of mechanical components and overall maintenance. But the biggest advantage
  • Two modes are better than one for heavy-duty hybrids
    , " in this context, describes the configuration of transmission gearing for optimal efficiency at varying speeds and power levels. Unlike conventional continuously variable transmissions, the 2-Mode full hybrid 's electrically controlled system uses no mechanical belts or bands. Shifts between modes are synchronous
  • Cabinet Cooling System Technologies to Consider when Planning Your Next Project
    Electrical control equipment is becoming increasingly sophisticated as designers add more features to what used to be relatively simple electro-mechanical control gear. Circuit breakers now have sophisticated electronic controls, variable speed drives and soft starters have replaced motor
