Common VFD and Motor Driven System Misapplications

  • July 2023
  • Number of views: 2595
FREE for Members of EASA
Webinar recording

Variable frequency drives (VFDs) are more common than ever before.  Sometimes when a VFD is introduced into a motor driven system, system reliability suffers. This recording addresses some of the common factors that reduce motor driven system reliability and how to correct them.

Help Customers Save Energy & Money with Power Drive Systems

New study shows major savings potential with power drive systems on commercial pumps

  • December 2020

Webinar recording

While adding variable speed capability in commercial buildings is not a new idea, a new analysis confirms major energy and cost savings is available by pairing those products with a power drive system (PDS) – regardless of a pump’s load variability. A PDS combines an electric motor, adjustable speed controls and sensors that provide feedback to the equipment, allowing the equipment to slow down or speed up to meet current demand. This idea and the added flexibility a PDS can provide may be even more important as we move forward in uncertain times.

Shaft and Bearing Currents

  • March 2020
  • Number of views: 14577
FREE for Members of EASA
Webinar recording

This webinar explains what shaft currents are, what causes them, and differentiate between the two common causes. It also discusses and compares methods to mitigate shaft currents and explains why the different causes of shaft currents require different solutions.

Induction Motor Speed Control Basics

  • March 2019
  • Number of views: 8449
Webinar recording

Induction motors are most often applied to what are essentially constant speed drive applications. However, the use of induction motors in variable speed applications continues to grow, primarily due to technology advances in power electronics. This webinar will review speed control basics for induction machines.
