Innovative VFD-Motor Matching Doubles Motor Life

The perfect match between electric motor and VFD has finally been taken to the next level. WEG’s massive investment in research and development and the joint expertise of electric motor and VFD design engineers has addressed two of the major drawbacks of modern PWM drives – increase in motor temperature rise, and fast transient high voltage peaks, the consequence of both being a dramatic reduction in motor life.

WEG’s CFW09 drives minimize voltage surges by carefully regulating the time between pulses of their IGBT transistors. This decreases the possible surge magnitude by 50% allowing longer cable runs without detrimentally affecting motor insulation.

Patented Flux Optimizing technology decreases motor temperature rise by as much as 11%. Since insulation life is doubled by every 10° C decrease in its operating temperature, this new technology can double the life of a motor. A combination of low VPEAKS and dV/dt at the motor terminals, lower motor temperature rise, high performance drive and motor architecture makes WEG products the perfect solution for the most arduous industrial applications.

This new technology redefines the concept of a matched drive and motor package, with concrete benefits to users over and above the usual concept of matched packages.

Quality

Quality is not just a beautiful word at WEG.

“Quality” is not just a fancy word at WEG. Quality is a natural process, a component of the company’s policy. Committed to continuous improvement, the process is based on three key features:

  • WEG’s Quality and Productivity Program, sets goals to be achieved by employees, allowing the company to be more competitive. A profit-sharing incentive to employees is also included.
  • Quality Control Circles were created to encourage worker participation in the administration process. This includes the exchange of ideas, teamwork and the encouragement of creativity in problem solving. Today, WEG’s Quality Control Circles serve as a national standard for quality.
  • Training is considered an investment in the company’s greatest asset, its employees. WEG invests .6% of its income in training programs annually

Billions of Dollars in Energy Could Be Lost Annually Due to Poor Motor Sizing

Energy efficiency losses through oversizing of pump electric motors by engineers are commonplace and, if the motor specification far exceeds the application, it could be costing industry billions of dollars in wasted energy.

ATLANTA, Georgia, July 9, 2008 – WEG Electric Motors Corp. (www.weg.net), a leading global supplier of motors, drives, controls, generators, and transformers, explains how proper motor sizing could easily save vast amounts of energy. Energy efficiency losses through oversizing of pump electric motors by engineers are commonplace and, if the motor specification far exceeds the application, it could be costing industry billions of dollars in wasted energy.
