Applications of the technology range from miniature motors that can be held in one's hand to pieces of rotating equipment that are considerably larger than the tallest man. Refinements of this technology, fueled in recent years by improved reliability and performance of electronic devices, are occurring at a more rapid pace than ever, resulting in greater performance at lower cost. The net result is a new world of technical and economic opportunity for those who are astute enough to grasp the potential of this technology in its various and sundry forms.Variable speed drivesVariable speed drives.621.85Spitzer David William6350MiAaPQMiAaPQMiAaPQBOOK9910815132003321Variable speed drives3944277UNINA
