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

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.

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 characterized 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.
