Energy Efficiency

Introduction to Energy Savings

Introduction to Energy Savings

We are all familiar with the figures: around 50 per cent of industrial energy demand in the European Union comes from electric motors. This represents CO2 emissions on the order of some 578 million tons in 2020. The extension of the efficient motors under the regulation will avoid an additional 40 million tonnes of CO2 each year and with that the annual energy bill of EU households and industry will be reduced by approximately €20 billion by 2030. (Source: European Commission)

Bauer Gear Motor welcomes the EU Directive

EU Directive 2009/125/EC (Ecodesign Requirements for Energy Related Products) defines the conditions for these savings. The EU member states gave their support to the new rules for reducing the energy demand of industrial motors. The regulation (EU) 2019/1781 is laying down ecodesign requirements for electric motors and variable speed drives pursuant to Directive 2009/125/EC. 

The regulation sets out two stages: from 01 July 2021 onward, motors must comply as a minimum with MEPS (Minimum Efficiency Performance Standards) energy efficiency class IE2 (High Efficiency) within the power range >=0,12 to <0,75kW and IE3 (Premium efficiency) for motor powers >=0,75 kW. From 01 July 2023 single phase motors and Ex eb increased safety motors must comply as a minimum with energy efficiency class IE2 (High Efficiency) with motor powers >=0,12 kW.

Company policy

Bauer Gear Motor sees ecodesign as an affirmation of the group‘s own efforts. Bauer Gear Motor strives to reach its goals with minimum consumption of raw materials and energy, the least possible impact on the environment, and efficient use of resources. A memo to employees says: "Bauer Gear Motor fully supports the Directive, especially because most of our developments are committed to energy savings. The philosophy of the Directive is also in tune with our system of values and our mission."

As a responsible manufacturer, Bauer Gear Motor provides drive systems for all IE classes, in addition to advanced solutions that go beyond the minimum statutory requirements. Competent consulting and knowledge transfer enable our customers not only to use cost effective solutions, but also to benefit from sustainable energy savings. Asynchronous systems designed for all kinds of operation. PMSM optimized for use with frequency converters, with the ability to achieve - even in partial load operation - the greatest energy savings.

We support our customers with advice and assistance for their future security.

What does the EU directive mean?

TheIEC 60034-30-1 is an international standard for energy-efficient motors which will be transferred step-by-step to national regulations worldwide. Electric motors account for approximately 1470 TWh of the total energy demand of the EU in 2020. Using energy efficient motors would reduce approximately €20 billion by 2030 every year, thereby reducing the total cost of ownership (TCO) and reducing global warming.

As things stand today

IE (International Energy Efficiency) efficiency classes:

  • IE1 = Standard Efficiency
  • IE2 = High Efficiency
  • IE3 = Premium Efficiency
  • IE4 = Super Premium Efficiency

The IE classes cover the following:

  • Rated voltage 50V up to 1000V
  • Power 0,12 kW to 1000 kW
  • Number of poles 2, 4, 6 or 8 (50, 60 and 50/60 Hz)
  • Operating mode: Continuous operation (S1, S3>=80% and S6>=80%)
  • Consideration of geared motors
