EMSA policy brief: Key findings on digitalisation technologies for motor systems
This Policy Brief gives an overview of the content of the EMSA report on
Classification of digitalisation technologies for electric motor driven systems.
The report identifies 13 digital technologies with the potential to influence energy
consumption in electric motor driven systems and contains definitions, descriptions and examples in this area.

As electric motors systems represent such a large share of the overall electricity consumption (over 50%), large savings potential could be made available by the use of energy-efficient motor systems both in new installations and by accelerating the replacement of old inefficient motors. Since electric motors are very reliable, their lifetime is long (according to recent studies it may exceed 20 years) which translates into a very inefficient existing stock despite worldwide policy efforts. This paper analyzes the current efficiency of the installed stock and the causes for its low efficiency, possible policy options to increase its the efficiency, the role of new technologies and improvements possible by targeting the entire motor system at the time of motor replacement. The paper presents an innovative analysis of the estimated impact of increasing the uptake of high-efficiency motors and motor systems; effective policies could translate into 100 TWh/year in the European Union if additional measures, such as addressing oversizing, proper controls (VSDs) and digitisation, are also implemented
ENERGY-EFFICIENT ELECTRIC MOTORS AND MOTOR SYSTEM
Improving energy efficiency is the fastest, cheapest and cleanest way to get reliable power to more people. Well over half of the world's electricity is consumed
by just four products: electric motor systems, lighting, room air conditioners, and residential refrigerators.
ENERGY EFFICIENT INDUSTRIAL MOTORS
Electric motors are of utmost importance in industrial as well as agriculture sector. These motors found their application as constant speed drives with very low rating as well as variable speed drives with very high rating. This paper describes the various factors affecting the efficiency of motor and method to increase it on the basis of comparison with various standards. An incremental difference in the efficiency is also discussed.
