I have worked with drives for over 30 years. They are not much to look at. They are put into beige cabinets, and the cabinets are locked away in motor control rooms. Open the cabinet door, and things get even geekier – a bunch of wires and blinking lights.
Many of the people producing drives see them as so many thousand beige cabinets. Get the order, assemble, test and ship them off the loading dock. They know it is an electronic device for controlling a motor somewhere. Boring!
From the beginning, I saw drives as a means of getting a job done. That was the view of most of the drive-control engineers I ever worked with. Drives are used to form, draw, dry, calender, and wind webs. There is some repetition, but always interesting twists. When not working in web-handling, I might configure a drive for marine propulsion, to test cars or engines on a dynomometer, or to lay fiber cable on the ocean floor.
Most important, drives keep the wheels of industry turning – giving us the jobs we need.
