Pumping, fan and compressor systems consume most of the motor electricity power in both
the industrial and services sectors. A variable speed drive brings relevant improvements in
a fluid system leading to energy saving that further on can be translated into Mtons
reduction of CO 2 emissions.
Standards and regulations are being adopted for fluid handling systems to limit the less
efficiency pumps out of the European market on the coming years and a greater potential in
energy savings is dictated by the Energy Efficiency Index (EEI) requirements for the whole
pumping system and integrated pumps. Electric motors also have an International
Efficiency (IE) classification in order to introduce higher efficiency motors into the market.
In this thesis, the applicability of mid-size common electric motor types to industrial
pumping system took place comparing the motor efficiency characteristics with each other
and by analyzing the effect of motor dimensioning on the pumping system and its impact in
the energy consumption.
