The consumption of electric drives in industry and manufacturing accounts for almost two-fifths of all electricity in Germany. Electric motors are thus considered to play a key role in energy savings. Energy savings are particularly high in the power range between 0.75 kW and 40 kW, since this is where most operating hours occur each year. At same time, in addition to energy savings, the maintenance of electric drives also plays a decisive role, as sudden failures can result in high costs due to production downtime or repairs. Against this background, a universally applicable condition monitoring system has been developed that allows electrical performance parameters to be analyzed in a simple and compact way in an industrial environment. The aim of this article is to show the added value of electrical power measurement for energy saving and maintenance planning in mechanical glass processing.
