Synopsis

In Dynamos, Motors, Alternators, and Rotary Converters, learn how energy moves between mechanical and electrical forms and why efficiency matters in electrical machines.

This classic reference lays out the core ideas behind dynamo-electric machines, including dynamos, alternators, and related converters. It covers definitions, measurement of electrical energy, field and armature design, and practical considerations for achieving reliable, sparkless operation. The book blends theory with historical development and real-world engineering examples to show how machines convert energy with minimal loss.

• Understand the four basic machine types: dynamo, alternator, motor, and alternating-current motor.


• Explore how electrical energy is measured and quantified, including efficiency and losses.


• Learn about field excitation, armature winding, and strategies to balance cross-induction and sparking.


• See practical design considerations and examples that connect theory to real equipment.

Ideal for readers of technical history and engineers working with electrical machinery, from students to practitioners seeking a solid grounding in the field.

Présentation de l'éditeur

Excerpt from Dynamos, Motors, Alternators, and Rotary Converters

The present edition of Mr. Kapp's work, published originally in England, is a translation of the third German edition, which has been revised and much enlarged by the author. In this edition reference to stationary transformers has been omitted, since the matter has been fully dealt with in a separate work by the author.

The third edition further differs from the previous ones in the more thorough treatment of sparking in direct-current machines, of magnetic leakage, of direct-current armature windings, and of the excitation and compounding of such machines.

The armature windings and armature reactions of alternators have also been much more fully dealt with. The chapters dealing with rotary field motors and rotary converters arc new, as is also the theory of the hunting of parallel-coupled alternators.

This book is further supplemented from the practical standpoint by the author's work entitled "Dynamo Construction: Electrical and Mechanical."

Mr. Kapp has endeavoured to present the calculations in as simple a form as possible, and, above all, to substitute where practicable graphical for analytical methods, or at least to employ both.

It will be observed that the book is intended particularly for technical readers, and contains practical suggestions of great value, enabling the problems which present themselves in the design of machines to be dealt with with all the accuracy needed in practice. On the other hand, no extremely long calculation will be found in it, nor any not having an immediate application.

The author regards the factors to be taken into account in the design of a dynamo as being too numerous to permit of the introduction of all into the calculation, which can consequently only be an approximation, and considers it useless to strive to attain a fancied exactitude. The author's methods and skill in approximations cannot fail to appea...
