Synchronous Motors (IEC)

Siemens rugged high voltage IEC synchronous motors are used in a wide variety of applications, which call for the highest power and torques capabilities, as well as a maximum plant availability. In applications such as central gas compressor stations, blast furnaces, rolling mills or ore mills. They are available for mains and converter operation in power ratings from 2.1 up to 100 MW and higher, voltages from 1.5 kV up to 13.8 kV, torques up to 2500 kNm and speeds from 7 rpm up to 7000 rpm in the double-digit megawatt range. Housing, mounting, active components, ventilation and cooling system are optimally matched to each another. Thus, they set the benchmark when it comes to reliability.
