Germany High Efficiency Tender

Siemens is presenting the Simotics SD motor series as part of the Digital Enterprise Virtual Experience at the Hannover Messe 2021. The standard version of Simotics SD 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 20191781 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. The directive defines the eco-design requirements for electric motors and speed control systems.This European directive 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. Highly efficient motors also allow users to save energy lower their operating costs and reduce CO2 emissions. Such motors are typically used in the process industry for pumps fans compressors extruders mixers agitators centrifuges rollers or winders. This applies primarily to the Water Wastewater Chemical Oil Gas Cement Paper Marine and Metal processing industries.The motors of the explosion proof Simotics XP series also exceed the currently required efficiency standards. They are also offered in IE3 and IE4. IE3 is standard in the increased safety Ex eb type of protection. This means that the requirements that come into force in 2023 and demand efficiency class High Efficiency IE2 are also exceeded here. Another example from the Simotics portfolio is the Simotics reluctance motor. This motor is characterised by the highest efficiency levels comparable to IE4 even in the partial load range. In the system with a Sinamics converter it exceeds the minimum requirements of the highest defined system efficiency class IES2. Highly efficient motor technologies can sustainably reduce the energy demand of industry and contribute to lowering global CO2 emissions. After all according to the German Electrical and Electronic Manufacturers Association ZVEI around 70 percent of the energy demand in industry is required by electric motors.
