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 […]

Inverters -are you using what’s inside?

  As with many factory automation products, users see VSDs simply as a way of controlling motor speed. But have you wondered why the makers of AC inverter drives regularly reinvent their products, or how they can help you? Consider for example Mitsubishi Electric’s high-performance FR-A800 inverters. Specifically designed for precision machine control, the FR-A800 […]

VSD for wind/unwind applications

  Mitsubishi’s wind/unwind inverter provides control technology for continuous roll-to-roll applications. It is for the processing of a web (sheet of a paper, film, or other material) from the unwinding roll to the winding roll. Moreover, it features stable winding and unwinding performance, and ease of start-up and adjustment. The FR-A800-R2R is a dedicated roll-to-roll […]
