• How VFDs Save Energy
  that a VFD has is the ability to save the user money through its inherit nature to save energy by consuming only the power that's needed. The main question now is, How does a VFD accomplish this? The simple answer to this question is power conversion. A VFD is similar to the motor to which it's attached...
• Advantages of Electric Clutches When Driving Components Off a Gas or Diesel Engine
  Design ran an editorial in their August 7 edition on how Ogura's clutches are being used in the oil field industry to allow natural gas engines to cost effectively replace electric motors on pump jacks and how ideally they are suited for continuous exposed environmental conditions....
• How To Create Nothing - Faster (.pdf)
  ­ By completely. top into the drive, feed it a new. eliminating the possibility of oil. motion profile, and it's ready to go.". leaks, Milacron pointed out that an. said Nichols. all-electric machine became the. So, how difficult is it to retrofit. hydraulic cylinders with electro-. obvious choice...
• Brushed DC Motor Fundamentals

• Understanding Electronic Motor Drives
  and efficiency from an electric motor. A motor drive controls the speed, torque, direction, and resulting horsepower of a motor. Dc drives typically control a shunt-wound dc motor, which has separate armature and field circuits. Ac drives control ac-induction motors and, like their dc counterparts...
• A Perspective on Piezo Motors (.pdf)
  transducers, and ignition. systems. Early motors developed for commercial applications used high voltage drives. Years ago, when Clack still had. hair, a marketing manager handed me a piezoelectric motor and a driver with an instruction sheet in Japanese. and said "see how this runs". Being...
• Tiny Motors Make Big Moves
  package. Unfortunately, some things don't scale well. For example, the power of a standard electric motor with magnets and coils drops off noticeably as it becomes smaller. How it works. Piezomotors move due to piezoelectricity, a property of certain materials to generate an electric charge when placed...
• Air Motors for the Paper Production Industry
  be applied in a wide spectrum of fields due to their diverse design versions, simple construction, light weight, wide speed ranges and explosion safety. They work on a simple principle: The air created by a compressor is used to rotate a shaft. In a vane motor, as the rotor starts to turn in an eccentric...
• How tight is right?
  of these metrics in pretightened fasteners. Here's how it works: A computer-controlled dc electric-motor drive inputs to a torque-angle sensor. The sensor output shaft couples to a fastener (bolt portion) to be tested while a research head traps the nut. The research head contains a torque sensor...
• Technical Reference: Motor Parameters Application Note (.pdf)
  and convenient to measure. It will also give the. relationships between certain motor parameters, show how some values differ depending on the winding type of. the motor, and show how some parameters are not dependent on the winding type. These formulas and. relationships will then be compared...
