Developed by Finnish engineering company Strömberg, which went on to become part of ABB, the VSD was used in a commercial application for the first time in 1975 at a sawmill in Finland. The LV VSD ...

Using variable speed drives on pumps reduces parasitic energy loss, enables proper maintenance and lowers capital costs. This article examines a method for determining the optimal number and speed of ...

Although there are substantial efficiency improvements to be gained through motor upgrades, even greater energy savings are possible when a high-efficiency motor is paired with a variable-speed drive.

The Department of Energy (DOE) now requires new pool pump motors and replacement dedicated purpose pool pumps (DPPP) for most in-ground pools to be variable speed because they are more energy-… ...

Government incentives and tax credits have made the switch to heat pumps more affordable for consumers who want to lower energy costs and improve efficiency in their homes. As the “heart of the HVAC ...

Abstract: Motor efficiency is important, but it is a small contributor to overall system efficiency. This paper will not review motor efficiency as a single important factor for energy saving, but the ...
