For a Truly 'Green' System: A VFD for Energy Efficiency, An AEGIS™ Bearing Protection Ring for Sustainability

摘要

The new green movement incorporates two basic tenets: energy efficiency and sustainability. In order for a building, process, or product to be truly "green", it must achieve both these goals. For equipment or systems powered by motors to be "green", however, often requires design engineers to deal with bearing currents, an unwanted side effect of energy- efficient variable frequency drive (VFD) technology.
