We are all familiar with the figures: around 70 per cent of industrial energy demand comes from electric motors. This represents CO2 emissions on the order of some 427 million tons. The European Commission is convinced that savings equal to the electrical power consumption of Sweden could be achieved with suitable measures.
The 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 at a meeting of the ecodesign regulatory committee on 11 March 2009.
The Class codes IE1, IE2, IE3 and IE4 have been introduced. This system is similar to the IP, IM and IC codes uses for many years in the electrical machinery industry. IE stands for 'International Energy Efficiency Class‘
Regulations & Standards
The EN 60034-30-1 is an international standard for energy-efficient motors which will be transferred step-by-step to national regulations worldwide.
The Bauer energy saving motor ranges DSE, DHE and DPE with power ratings 0,12 ... 45 kW for energy efficiency classes IE1, IE2 and IE3 offer customer advantage and long lifetime.
Energy Savings Calculator
Energy is not only saved when using energy efficient motors but also with the correct choice of gearbox, drive system and motor control. The energy saving calculator from Bauer helps you to find the optimised solution.
