Electric Machines. Steady State and Performance with Matlab/Электрические машины. Стабильное состояние и производительность с Matlab

Издание на английском языке
Electric energy is paramount to prosperity while inspiring social responsibility of industry.
Intelligent use of electric energy implies better electric generators to “produce” it in modern distributed power systems, with day by day more renewable energy penetration.
It also implies better electric motors used more and more in variable speed drives via power electronics and digital control to save energy and increase productivity in all industries where the output varies in time.
Electric machines are reversible in the sense of switching easily from motoring to generating. New industries such as e-transport, robotics, e-building appliances, renewable (wind) energy have extended quickly recently with similar trends in the near and distant future.
The present textbook is intended as for the first semester treating electric transformers, rotary and linear machines steady-state modeling and performance computation, preliminary dimensioning and testing standardized and innovative techniques. Numerical examples/problems are scattered all over the book to bring a feeling of magnitudes. Proposed problems are available at the end of all 6 chapters; also 9 MATLAB/SIMULINK user-friendly computer programs that illustrate main machine characteristics are available online. The textbook may directly be used also by R&D engineers in industry as all machine parameters and characteristics are calculated by ready to use in industrial design mathematical expressions.
Educating electrical engineering students and R&D engineers in industry in electric machinery and drives faces new challenges as the recent technical progress in the field has been staggering.
