Variable Speed DrivesSince the 1960s, the installed base of electronic high capacity adjustable variable speed drives (ASD) has grown from a few applications to tens of thousands of installations globally
Page 3
Variable Speed DrivesAdvances in communications, micro- processing, high-speed switching and cooling systems have made these products more reliable, smaller, and more commercially acceptable in industry.

Variable Speed DrivesTrends in technology from the LCI type to the PWM VSI type drives are leaving the installed base of LCI drives in a condition of obsolescence.
Twenty (20) Year Trend of HighCapacity Drives
