The standard version of Simotics SD is offered by Siemens in the efficiency class Super Premium Efficiency (IE4) across the entire power spectrum from 2.2 to 1000 kW and for the number of poles 2, 4, as well as from 75 kW for 6 poles and from 55 kW for 8 poles. Simotics SD in IE4 thus exceeds the so-called ErP Directive 2019/1781 (energy-related products) – both the first stage, which will be valid by July 2021, as well as the next, which will apply from July 2023. In accordance with the regulation, Siemens offers the Simotics SD motor series consistently in IE4 for all affected motors. In addition, however, also for motors with an output of up to 1000 kW as well as for 8-pole motors from 55 kW, which are still exempt from the second stage from 2023. Users of Simotics motors can thus meet the increasing requirements for energy efficiency and environmental compatibility in the long term. Highly efficient motors also allow users to save energy, lower their operating costs and reduce CO2 emissions.
