Siemens has further expanded its range with the integration of Loher GmbH and now offers a complete portfolio of explosion-protected drives: from 0.1 kW to 100 MW, with a speed range up to 15,000 rpm also in the megawatt range, as a standard or customized solution and for all applicable ignition protection types in dust and gas atmospheres. more

Variable speed three-phase current systems with frequency converters are also establishing themselves increasingly in the cement industry. They ensure exact processes, reduce the maintenance effort and save energy. more

With about 1200 m/min, converted 72 km/h, the paper races over the rollers, waltzers and winders. To avoid the web tearing at this speed and to guarantee a consistent paper quality, the drives of the new paper machine of the paper and cardboard factory Varel GmbH & Co KG must bring top performance. more

With three infeed concepts, the Sinamics drive family has the right solution for every application. Infeed of current without mains feedback as the most economical solution for exclusively motorized operation, standard solutions with uncontrolled infeed/feedback unit for occasional generator operation and controlled infeed/feedback unit for particularly high demands on system availability and mains quality. more

The expectation that fuel prices will increase is just one reason of many for the increasing use of fuel-saving variable-speed electric drives on ships and in the offshore sector. The range of applications for variable-speed electric drives extends from the main propeller drive, through bow and stern thruster drives, pumps, fans up to winches. more

Two thirds of the power consumption in industrial installations are caused by electrical drives. Using efficient drive technology can therefore result in substantial savings. more
