  • Electric Motor Handbook
    . It embodies the premise that effective application of electric. motors requires an understanding of the internal mechanisms and. physical principles on which the motor operates. For this reason it. incorporates quite a lot of "theory" of operation. However, it also. incorporates much practical
  • Introduction to Electric Motors
    Electric motors, both ac and dc types, come in many shapes and sizes. Some are standardized versions for general-purpose applications. Others are intended for specific tasks. In any case, motors should be selected to satisfy the dynamic requirements of the machines on which they are applied without
  • WD Bearings Application: Electric Motors
    Introduction. WD Standard Bearings. WD Special & Precision Bearings. Free Catalogues. Home > Electric motors. Electric motors. Large Electric Motor. Large Electric Motor is an automatic device that uses error-sensing feedback to correct the performance of a mechanism. The term correctly applies only
  • EPACT & Energy Efficient Electric Motors
    Today is truly an exciting and challenging time for specifiers, buyers, users and manufacturers of industrial electric motors. It is a time of change in the motor industry rivaled, in recent times, only by the introduction of re-rated "T" frame motors in the 1960s. But there is a difference between
  • Adhesives hold electric motors together
    Edited by Lawrence Kren & Victoria Reitz Electric motors are smaller, faster, more powerful, and more prevalent on automobiles than ever before. This is forcing motor designers to find new ways to shave cost in production and assembly. One area getting more attention these days is fasteners. Choose
  • How to make bearings last in electric motors
    . Rolling-element bearings in electric motors support and locate the rotor, maintain a small and consistent air gap between the rotor and stator, and transfer loads from the shaft to the motor frame. The correct bearings for an application let a motor run efficiently across its design speed range, minimize
  • Pressure Transducer Usage in VFD Control for Electric Motors in Machinery and Factory Automation
    VFDs, or variable frequency drives, are a common tool in electric motor control. VFDs, simply put, control electric motors by modifying the power input frequency to the electric motor. VFDs used in conjunction with electrically driven pumps can be made to control both the flow rate and the output
  • Electric Motor Testing-The New Kid on the PdM Block
    While vibration analysis and infrared thermography. have been widely used for years as part of predictive. maintenance programs, Electric Motor Testing (EMT) is. a relative newcomer to condition monitoring. In reality. though, the tests utilized by modern EMT systems have. been around for years
