Energy efficiency measures in electric motors

2019-10-15Electric motor systems (EMS) cover a remarkable share of industrial power consumption. Despite the wide set of apparently cost-effective opportunities to improve energy efficiency in this cross-cutting technology, often decision-makers do not take them, as the detail for a specific decision can be too high, resulting in an implementation rate quite low.
