Power and productivity for a better world™

Motors use almost one third of the world’s generated electricity. So it is safe to say that reliable motor operation is crucial to our modern way of life. Yet millions of these motors are not run optimally. The wear and tear associated with frequent starts and stops cause unplanned stoppages and shortened operational lifetime. The uptime of full-speed motors would be greatly improved if softstarters were used. As the name implies, softstarters enable smooth motor starting and stopping, thus optimizing both new and existing motors. For motor protection on a global scale, by simply using softstarters,...

Xylem - South Africa ABB softstarters provide efficiency in the mining industry One of Xylem’s water solutions helps to prevent flooding in mines. Previous softstarters needed a lot of extra protection equipment. Xylem was looking for a simpler solution that would ensure reliability even at a depth of 3,500 meters. Reducing the number of components by 80 percent shortened installation time by 60 percent. By cutting costs in half, Xylem can sell twice as many panels with softstarters than before. Why softstarting matters to Xylem Installation time reduced by Total panel cost reduced by For more...

ABB softstarters Improving industrial processes around the globe 1 Softstarters can do wonders for your operations. Packed with useful features, they reduce the wear of your equipment, improve the reliability of your processes, and increase overall productivity. Controlling pumps Controlling fans Eliminating water hammering with torque control Water hammering is a common problem with pumps. It typically results in a lot of wear on pipes and valves when stopping the pump. ABB softstarters feature torque control stop which eliminates water hammering and prolongs the lifetime of the system, while...

Controlling conveyor belts Controlling compressors Avoid overheating with overload protection Too much material on a conveyor belt may cause overload and overheating, reducing the reliability and longevity of the motor. The ABB overload protection feature shuts down the motor in case of overload, avoiding overheating. Full control of current with current limit Many applications are sensitive to high or variable starting currents. The feature current limit makes it possible to start the motor securely even in a weaker network, improving the availability of the equipment and system. Reducing the...

Direct-on-line Direct-on-line starting (DOL, also across the line starting) is the easiest and most commonly used starting method. It is suitable for stable networks and mechanically stiff and well-dimensioned shaft systems due to the high current and torque generated during start. DOL starting is uncontrolled, which means that the motor will start with maximum current and torque regardless of load type. Star-delta A star-delta starter reduces current and torque during start. The starting current is about one third compared to direct-online starting, although it also reduces the starting torque...
