Excerpt from The Dynamo: Its Theory, Design and ManufactureSince the last edition of the present book great progress has been made in the science of dynamo design, and even more in the art of dynamo manufacture. In the continuous-current field the increase in the size of modem machines has necessarily brought about the adoption of multipolar forms, while the demand for power and traction generators has led to the reintroduction on a widely ext...

Excerpt from The Dynamo: Its Theory, Design, and ManufactureIN writing the present book it has been the endeavour of the authors to furnish to students a simple, yet accurate, account of the theory and design of the modern dynamo. That the attain ment of this aim is no light task we are only too well aware. Such a book, if it is to be of use to those who are either engaged or about to engage in electrical engineering as a pro fession, must com...

Excerpt from The Dynamo, Vol. 1 of 2: Its Theory, Design, and ManufactureOn the continuous-current side the carbon collecting brush still holds the field, but much work, both experimental and theoretical, has been done towards the elucidation of its action. The treatment of commutation and of the sparking limitations of the dynamo has therefore been recast and expanded in the light of later researches, especially those of Prof. E. Arnold, to w...

Excerpt from The Dynamo, Vol. 1 of 2: Its Theory, Design, and Manufacture The interval since the last edition has added but little to the theory of the Dynamo, although in its practical design and art of manufacture many changes have been brought about by the necessity for the utmost economy in materials and labour to meet the stress of keen industrial competition. Whether for continuous-current dynamos or alternators, the drum armature with ...
