Help Customers Save Energy & Money with Power Drive Systems

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

  • December 2020
  • Number of views: 864
FREE for Members of EASA
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.

Natural Frequency Testing – Bump Tests and Modal Analysis

  • October 2020
  • Number of views: 1253
FREE for Members of EASA
Webinar recording

Anyone dealing with installed machinery, or even test running motors in the service center, will encounter instances where structural resonance is amplifying machine vibration. The machine may meet stringent specifications in one instance but exceed acceptable vibration levels in another. A good understanding of natural frequencies and the tests necessary to identify them will help solve these vexing situations.

Working with the No Nameplate Motor

FREE for Members of EASA
Webinar recording

Customers will often send in a motor with no nameplate and having little knowledge of the machine’s ratings. This webinar guides attendees through the process of evaluating the machine using core size, winding data and diagnostic testing to assign reasonable ratings.

Circulating Currents in AC Stator Windings

  • August 2020
  • Number of views: 902
FREE for Members of EASA
Webinar recording

This webinar recording discusses the equalized connections found in an increasing number of factory windings, explains why they are used, and addresses whether or not they are needed when converting a concentric winding to a lap winding. Alternatives, such as changing the number of circuits, or the special extra-long jumpers, are also compared.
