Direct And Alternating Current Machine Design

Excerpt from Direct-and Alternating-Current Machine Design Being Instructions for the Design of Motors and Generators Branches of Science Involved in Dynamo De sign. - The following discussion of the design of dyna mos and motors will be confined to the consideration of direct-current machines. The design of a dynamo and motor relates to three essen tial parts: first, the armature carrying the conductors in which the electric energy is generated or absorbed; second, the field magnet that produces the magnetic field or flux in which the armature revolves; and third, the various mechanical parts and arrangements necessary to carry out the electrical and magnetic actions. Thus, three great branches of science - electricity, magnetism, and mechanics - are involved. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
