Introduction to Variable Frequency Drives

Date: February 14th, 2023
Time: 1:00 PM (EST)
PDH Credits: 1


Variable frequency drives (VFDs) are a common tool for improving process and quality control and for realizing energy savings in pumping systems. This webinar outlines the general concepts for using a VFD in pumping applications and covers their fundamental principles of operation. Participants will be presented with application considerations that are typically outside the boundaries of the VFD, such as the environment and the electrical system, but that have a significant influence on its selection and operation. Also covered are safety and troubleshooting of variable frequency drives and their proper maintenance.

Learning Objectives

Upon successful completion of this webinar, participants will be able to:

  1. Understand the benefits of variable frequency drives and the types of pumping applications that are most suitable for their use.
  2. Be familiar with the basic architecture of VFD systems, including AC induction motors. 
  3. Understand the basic considerations that apply to selecting and applying a VFD in a pumping system
  4. Understand how the environment (temperature, altitude, cooling, etc.) affects the selection and operation of a VFD
  5. Understand how the electrical system (grounding, power quality, input/output cables, etc.) affects the selection and operation of the VFD
  6. Troubleshoot the drive and electrical components and understand the likely causes of performance issues
  7. Troubleshoot the motor and mechanical components and understand the likely causes of performance issues
  8. Understand the key elements of VFD maintenance.
