The Siemens have the most integrated drive system with the reluctance motor and variant convertor. The accurate controlling property of these motors serve as the result of coordinated and harmonized drive working system. These motors have the energy efficiency which is outstanding and increased by 10% in the range of partial half load. They have the desired benefits in terms of robustness, reliability, performance, high voltage working, etc. For the main operation they are available in the range of 450 shaft height with efficiency class from 2.2kW to 1000kW.
