Energy Efficient Operation of Drives

Energy Efficient Operation of Drives: In many Energy Efficient Operation of Drives applications involving constant speed operation, induction motors operate under no load or light load for prolonged periods, such as in pressing machine, conveyors, rock crushers, centrifuges, drill presses, wood saw and, some machine tools. In such applications, saving in energy can be achieved […]

Application of Variable Speed Drives

Application of Variable Speed Drives: Several drives are driven at constant speeds by induction or synchronous motors, although operation of Application of Variable Speed Drives could lead to saving of substantial amount of energy. Such practice was adapted in the past because of nonavailability of efficient methods of speed control of induction and synchronous motors. One […]

Use of Efficient Semiconductor Converters

Use of Efficient Semiconductor Converters: Prior to development of Use of Efficient Semiconductor Converters, inefficient power modulators were employed in several applications. While replacement of these power modulators by the semiconductor converters in appropriate applications brings about substantial amount of energy saving, the cost of replacement can be recovered in a short period ranging from […]
