SIMOTICS SD Severe Duty Motors

General description

The Severe Duty motors with gray cast iron frames are especially rugged. This makes them the first choice for applications in the toughest of environmental conditions. They master dust or vibration in crushers and mixers as well as the aggressive atmospheres that prevail in the petrochemical and process industries.
Our well-proven 1LE1 motors up to efficiency class IE4 are available for line (DOL) operation. With IE4 the energy consumption can be reduced by up to 3 % compared to IE3. If you choose the 1LE1 platform you can switch to IE4 motors also at a later date, because all efficiency classes, from IE2 to IE4, have the same power rating – shaft height assignment. With Severe Duty motors in IE4 you opt for robust fixed speed drives on a future-proof platform.
Motors from the VSD10 line and VSD4000 line are designed for variable-speed operation with converters. The invest optimized system of SIMOTICS VSD10 motor and SINAMICS frequency converter offers a simple selection via catalog or engineering tool and fast commissioning via motor code for preconfigured drive parameters. The system comprising synchronous-reluctance technology and SINAMICS G120 converter is the best choice for especially energy-efficient operation. Synchronous-reluctance technology ensures especially high efficiencies in the partial load range and high dynamic performance – for high process quality.
