Excerpt from Design of Polyphase Generators and MotorsJust as the design Of machinery for continuous electricity crystallizes around the design Of the commutator as a nucleus, so in the design Of polyphase generators, a discussion Of the pre determination Of the field excitation under various conditions Of load as regards amount and phase, serves as a basis for acquiring familiarity with the properties Of machines Of this class. The author has taken the opportunity Of presenting a. Method Of dealing with the subject Of the predetermination Of the required excitation for specified loads, which in his opinion conforms more closely with the actual occurrences than is the case with any other method with which he is acquainted. In dealing with the design Of polyphase induction motors, the calculations crystallize out around the circle ratio, and this may be considered the nucleus for the design. The insight as regards the actual occurrences in an induction motor which may be acquired by accustoming one's self to construct mentally its circle diagram, should, in the author's Opinion, justify a much wider use Of the circle diagram than is at present the case in America.The author desires to acknowledge the courtesy Of the Editor Of the General Electric Review for permission to employ in Chap ter VI, certain portions Of articles which the author first published in the columns Of that journal, and to. Mr. P. R. Fortin for assistance in the preparation Of the illustrations.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
