As a result of this webinar you will be able to:

  • Specify the differences between efficiency ratings required by labeling standards and efficiency terms used in marketing and selling motors.
  • Describe the impacts improper sizing of motors has on operating efficiency, energy cost and motor life.
  • Discuss the operational differences between newer, more efficient motors and older motors.
  • Evaluate when ECMs make sense in place of traditional single phase motors.
  • Summarize the advantages and disadvantages of various motor protection equipment.
  • Explain the advantages and disadvantages of different types of VFDs and the use of specific types of motors with VFDs.
  • Identify potential power quality disturbances that can cause VFD operational issues, as well as various protection strategies.

Who should watch?
Engineers, energy managers, facility managers, power service planners, contractors, manufacturers, building owners and anyone involved in selecting, operating and maintaining motors.

Keeping up with relevant topics in the motors and drives market? Join us online to take a close look at issues related to the use of today's premium efficient motors and variable frequency drives (VFDs). During this live webinar we'll address the confusion surrounding efficiency terms, labeling and jargon to provide more clarity during the motors and drives selection process. We'll outline slight operational differences between new and old motors, explain when and where to use electrically commutated motors (ECMs) and how to properly size motors. In addition, motor protection and nuisance tripping problems will be discussed, as well as the new motor efficiency standards recently announced by the U.S. Department of Energy.

Join us to get the latest information on premium efficient motors and VFDs available today. We'll discuss operational differences between new and old motors, when and where to use ECMs, sizing, new standards for motor efficiency and more.
