The reduction of energy consumption through improvements in energy efficiency has become an important goal for all countries, in order to improve the efficiency of the economy, to increase energy supply security, and to reduce the emissions of CO and other pollutants caused by power· generation. 2 Electric motors use over half of all electricity consumed in developed countries. Typically 60-80% of the electricity which is used in the industrial sector and about 35% of the electricity used in the commercial sector in the European Union is consumed by motors. In industry, a motor consumes an annual quantity of electricity which corresponds to approximately 5 times its purchase price, throughout its whole life of aroun~ 12 to 20 years. Motors are by far the most important type of electric load. They are used in all sectors and in a wide range of applications, namely the following: fans, compressors, pumps, mills, winders, elevators, transports, home appliances, and office equipment, etc. It is their wide use that makes motor drive systems one of the main targets to achieve significant energy savings. As motors are the largest USers of electrical energy, even small efficiency improvements will produce very large energy savings.

Seminar paper from the year 2015 in the subject Engineering - Industrial Engineering and Management, University of Applied Sciences Mittweida (Faculty of Industrial Engineering), course: Electrical engineering, language: English, abstract: In addition to a brief introduction to the historical development of electric motors and considerations of electrotechnical and physical fundamentals, this paper contains a comparison of internal combustion engines and electric motors. Furthermore, requirements and operating modes of electric motors are explained. In the center of the work are treatments of selected electric motors in relation to structure, mode of operation and power range. The work ends with a conclusion in which the advantages and disadvantages of the motor types mentioned and further developments are considered. Electric motors have a major role to play in terms of potential savings in electricity consumption. Without sufficient measures, it is assumed that worldwide electricity consumption by means of electric motors will almost double by 2030. Electric motors are responsible for about 40 percent of total electricity consumption worldwide and for about 70 percent of the electricity consumed by industry. In Germany, electricity consumption by electric motors is about 55 percent, in industry the share is 68 percent, the tertiary sector has a share of 48 percent and the share of private households reaches a level of 41 percent. About 96 percent of the electric motors sold in Europe are used by means of single-phase or polyphase alternating current, and for this reason they are the focus of the observations made in Chapter 7. The author points out with reference to the limited extent of the work to be provided in connection with the complexity of the topic, which is renounced in particular on the derivation, the bare denomination and the generalization of formulas and formula components.

Traditionally, electrical machines are classi?ed into d. c. commutator (brushed) machines, induction (asynchronous) machines and synchronous machines. These three types of electrical machines are still regarded in many academic curricula as fundamental types, despite that d. c. brushed machines (except small machines) have been gradually abandoned and PM brushless machines (PMBM) and switched reluctance machines (SRM) have been in mass p- duction and use for at least two decades. Recently, new topologies of high torque density motors, high speed motors, integrated motor drives and special motors have been developed. Progress in electric machines technology is stimulated by new materials, new areas of applications, impact of power electronics, need for energy saving and new technological challenges. The development of electric machines in the next few years will mostly be stimulated by computer hardware, residential and public applications and transportation systems (land, sea and air). At many Universities teaching and research strategy oriented towards el- trical machinery is not up to date and has not been changed in some co- tries almost since the end of the WWII. In spite of many excellent academic research achievements, the academia–industry collaboration and technology transfer are underestimated or, quite often, neglected. Underestimation of the role of industry, unfamiliarity with new trends and restraint from technology transfer results, with time, in lack of external ?nancial support and drastic - cline in the number of students interested in Power Electrical Engineering.
