OVERVIEW

Approximately 60% of industrial electricity demand is accounted for by motor systems, so the impact of motors on the environment is enormous. In the development of new products to make motors more energy efficient, a great deal of effort is concentrated on new materials that improve the efficiency and reduce the losses of motors. Rapid advances have also been made improving the functionality and reducing the losses of inverters in the development of compressors featuring variable-speed inverters that optimize loads on motors. These kinds of industrial equipment are seeing very rapid development and deployment to address the growing public need to step up environmental and energy conservation efforts. Meanwhile, the "Mountain Hotaru (firefly) Initiative" advocating and demonstrating the viability of renewable energy for environmental sustainability is gaining momentum, and this is driving the development of inverter technology which is indispensable for implementing small distributed power sources. We are counting on further advances in motors and inverters as fundamental core technologies as we move toward more environmentally friendly and energy-efficient industrial solutions in the years ahead.
