From 25th July all engines must be IE3 energy efficiency. We have adapted to the new regulations.
The energy efficiency of the electric motor is of fundamental importance, if we consider that 75% of the electricity consumed in the industrial sector is used for the power supply of the electric motors.
determines a classification of the performance of engines according to the IE code (International Efficiency):
The efficiency of a motor is the ratio between the output power available to the shaft and the electric power absorbed by the network, and to measure it you follow the directives of the standard EN 60034-2-1.
With Directive 2009/125 / EC has been defined a framework for the development of specific eco-design of energy-related products for the purpose of energy saving.
Based on the IE code, follow the EC regulation 640/2009.
“Squirrel cage induction motor, single-speed, three phase with a frequency of 50 or 60 Hz which has: 2 or 6 poles, maximum rated voltage of 1,000 V, rated power of 0.75 kW and 375 kW and continuous operation characteristics”.
From 1st January 2015 the electric motors with a rated power of 7.5 kW and 375 kW must have a level of efficiency IE3 or IE2, if they are equipped with variable speed;
From 1st January 2017 all motors with a rated power of 0.75 kW and 375 kW must have a level of efficiency IE3 or IE2, if they are equipped with variable speed.
You have to declare the nominal return at full load, 75% and 50%, level IE2 or IE3 and year of manufacture.
Both on products placed on the market and on those put into service. In summary, if the engine with lower efficiency IE2 has been purchased within 15/06/2011 it can be used without penalties. For this, the distributor can sell a motor not IE2 if purchased by that date.
