Regenerative drives convert braking energy into free electricity

ABB’s new ACS800-11 variable speed regenerative drives capture braking energy from electric motors. They return it in to the network as free electricity, significantly improving energy efficiency. In industry, electric motors are often used in applications with frequent brake applications. A braking chopper and external electrical resistors dissipate braking energy as heat. Resistor braking often […]

Linking asset maintenance and energy costs

Linking asset maintenance and energy costs   A recent white paper, Schneider Electric looks the relationship between asset maintenance and energy costs in pumping. Assets such as pumps need maintaining on an ongoing basis, and maintenance costs are 25% of TCO. Thus maintenance practices warrant examination of their contribution to energy-influenced savings. In pumping installations, […]
