The third stage of the Energy-related Product (ErP) Directive provides clear guidelines for the use of IE2, IE3 and IE4 motors. It also places new requirements on the use of motor starters and drives from 0 kW to 375 kW. For detailed information, download our white paper.

Energy-efficient motor control
Better energy efficiency makes your businesses more successful
In almost all industrialised countries, energy efficiency is now a key topic of interest for governments. Laws and regulations have been passed that mandate carbon-footprint and energy-consumption reductions in almost all areas of life. In many countries, clear targets have been defined and are being enforced by rules or additional energy taxes. Whilst this poses a challenge for industry, it simultaneously presents a huge opportunity, as sustainably engineered products are already seeing higher growth than less energy-efficient alternatives.
Energy usage statistics of electric motors
In industrial production, electric motors account for two-thirds of overall energy costs, and their energy consumption represents more than 95 % of lifetime costs. These two numbers alone demonstrate the potential of electric motors and the control devices in their vicinity for improving energy efficiency. The EU ErP directive has mapped a path towards more sustainable industrial production.

Energy-efficient motors - a new challenge for switchgear
Energy-efficient motors are not only characterised by significantly improved efficiency, but also by lower internal resistance. As a result, their inrush currents can reach magnitudes of 14 x IN. This means that the contact mechanisms in contactors can wear out very quickly and that nuisance tripping of the motor-protective devices may become a problem. In our white paper, we discuss the safe and reliable operation of energy-efficient motors.
Eaton's energy efficiency podcast
Here’s what some of the experts at Eaton have to say about embracing energy efficiency today in order to seize a world of opportunity tomorrow.
How our customers build energy-efficient machines
To be able to quickly switch between the required process speeds, we need variable frequency drives with maximum flexibility. The Eaton PowerXL DG1 is the perfect match for these requirements.
To minimise the risk of production downtime and to guarantee short response times in the event of a fault, paint manufacturer Dinova replaced the variable frequency drives in its mixers with Eaton products. The compact PowerXL DG1 drive with integrated motor protection relay eliminates errors, protects the mixer against mechanical resonance and reduces energy loss to a minimum by dynamically adjusting the voltage/frequency curve.
When the International Institute for Product Safety (I²PS) in Bonn, Germany decided to replace its old slip-ring motor with an asynchronous one, it also sought to improve the energy efficiency of the overall system. The company chose an electronic drive system consisting of a frequency inverter and a regenerative braking unit. The new system from Eaton combines improved energy efficiency with better usability.
In its search for a solution that would reduce the energy consumption of an air filter system, LS Automation opted for Eaton's motor starters and drives to simplify the integration of energy-efficient motors.
