Abstract
The electromagnetic torque, antagonistic to movement that the prime mover exerts in synchronous generator shaft contemporary, is the fundamental cause of the enormous amount of energy that consumed in thermoelectric plants, groups generators, hydroelectric, aero – generators, etc.; in the present text They analyze two old alternators from the century XIX: Ferranti and Hasselwander, greats British and German engineers respectively, while it is mentioned the homopolar generator, all seen today as museum objects due to their great value historical, however its behavior regarding harmful torque electromagnetic is much lower than in the synchronous current generator; it is demonstrable based on the study of both generators electrical than modifying the circuit magnetic current synchronous generator it is possible to generate with less torque electromagnetic, which is equivalent assuming rotation speed constant, at lower power consumption in the prime mover only by changing the magnetic circuit of the generator.
