Industrial drives:what does the future hold?

摘要

When Vacon's Stephen Takhar considers the future of industrial ac variable speed drives, he sees no radical changes on the horizon, but he does foresee numerous small but important developments. When considering the future of ac variable speed drives (VSDs), one thing is certain: because of the large energy savings that VSDs provide in many applications, they will be adopted more and more widely. This widespread adoption is itself a driver for change because, when drives are deployed in large numbers, factors like harmonic generation become increasingly significant.
