Technologies for Energy Saving in Industrial Field

摘要

This paper summarizes practical and developed techniques and technologies for energy saving in the industrial field. Newly developed high-efficiency electrical equipment or combined technologies, which are about 'power electronics', 'microcomputers' and 'motion control' in addition to the progress of sensing devices and monitoring systems, bring both energy saving and high productivity in the factory. The technology trend of new factory facilities is concerned about changing power sources from pneumatic (compressed air) or hydraulic power (oil system) to electrical direct-driven servomotor systems, which have the technical characteristics of fine-grained and regenerative control. These technologies are able to reduce and recover idling (standby) power consumption during the holding period at the production stage in the factory. The items in this paper were published as Technical Report No. 988 in January 11, 2004 by IEEJ, and that report is reviewed and updated in this paper.
