Understanding Variable Frequency Drives (VFD’s)

Process Efficiency

VFD, motor strategies for energy efficiency

Consulting-Specifying Engineer, February 3, 2014

A variable frequency drive (VFD) often is specified to save money by reducing energy consumption in pumps, fans, compressors, or any other motor loads that may be found in a typical building. These best practices will provide the engineer with information on how to specify a VFD to meet load conditions while achieving efficiency.

Learning objectives

  1. Understand when to specify VFDs.
  2. Learn which types of motors require VFDs.
  3. Know how to achieve efficiency when specifying a VFD to meet load conditions.
