IR's Sensorless Motor Control Platform For Variable-Speed Pumps Enables 50 Percent Reduction in Energy Consumption
International Rectifier, introduced a sensorless sinusoidal motor control platform that delivers quieter operation and higher efficiency for variable-speed pump applications up to 300W. By effectively controlling pump operation over a wide range of flow requirements, variable-speed pumps can cut energy consumption by up to 50 percent.
The latest iMOTION™ integrated design platform consists of a mixed-signal controller, the IRMCF371, and companion intelligent power module for the power stage, as well as algorithms, development software, and design tools. “Because variable-speed motor-driven pumps halve energy requirements, government legislation in many countries is driving the adoption of energy-efficient intelligent pumps, particularly in the water, waste-water, and building automation segments,” said David Tam, vice president of International Rectifier’s Energy-Saving Products. “The iMOTION platform achieves higher reliability and system performance by better controlling system load changes, improving control pump operations, and providing control over a wide range of load conditions as well as enabling smooth start-up conditions,” he added.
