Abstract :
The National Research Council, in its division of engineering, has appointed a committee on Core losses in electrical machinery. This committee has in course of preparation, with a view to publication, a bibliography, or list of publications on the general subject of core losses, from 1885 to 1922, including eddy currents, skin-effect and hysteresis, as well as their effects on the behavior of electrical machinery. In view of the great industrial and technical importance of core losses on the output, efficiency, heating and cost of electrical machinery and apparatus, it is very desirable that the subject should be thoroughly studied, so as to reduce such losses to a minimum.
