Xylem - South Africa ABB softstarters providing efficiency to the mining industry One of Xylems 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 3,500 meters depth. Reducing the number of components by 80 percent, shortened installation time by 60 percent. Costs cut to half has helped Xylem sell twice as many panels with softstarters as before. Installation time reduced by 60% Total panel cost reduced by 50%

— Common applications for softstarters Pumps, fans, compressors and conveyors A softstarter can do wonders with your operations. Packed with useful features, it reduces the wear of your equipment, improve the reliability of your processes and increase overall productivity. — Pump 01 Softstarters controling pumps 02 Softstarters controling fans Eliminating water hammering with torque control Water hammering is a common problem with pumps and typically results in wear in pipes and valves when starting and stopping the pump. The ABB softstarter feature torque control provides a soft pipe fill...

— Compressors 03 Softstarters controling compressors 04 Softstarters controling conveyor belts Full voltage start for scroll compressors For scroll compressors it is often necessary to start the motor in a very short time while still maintaining a low starting current. Full voltage start is a start mode that gives you almost a direct start but without the current peak. Increased flexibility with jog with slow speed After stopping the belt, it may be necessary to run the motor at low speed to correctly position the belt before resuming operation. The jog with slow speed feature makes it...

— Motor starting Why motor starting and stopping matters There are some common issues associated with starting and stopping electrical motors. Depending on requirement, different starting and stopping methods can be used. Direct-on-line starting (DOL) 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. A star-delta...

Softstarter Like direct-on-line and star delta starters, softstarters are used to start and stop motors in full-speed applications. It eliminates common problems associated with motor starting and stopping, including electrical surges, spikes and high inrush currents. Because it offers soft starting and stopping, a softstarter is the optimal compromise between a direct-on-line or star-delta starter and a variable speed drive in many full-speed motor applications. Variable speed drive Like a softstarter, a variable speed drive (VSD) can perform soft motor starting and stopping. However, the...
