High-efficiency motor series from Siemens now consistently available in efficiency class IE4

摘要

The standard version of Simotics SD motor series is offered 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). This European directive defines the eco-design requirements for electric motors and speed control systems and comes into force in two phases: From July 2021, it requires the efficiency class Premium Efficiency (IE3) for 2- to 8-pole electric motors from 0.75 kW to 1000 kW. From July 2023, it requires the efficiency class Super Premium Efficiency (IE4) for 2- to 6-pole motors of medium power from 75 kW to 200 kW. 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.
