Excerpt from Practical Directions for Winding Magnets for Dynamos While engaged in remodelling, improving, and standardising the dynamo machines manufactured by a large firm in Germany, the writer felt the need of some reliable method for examining the machines with a view to finding their best proportions, and also of some method for calculating the windings for the field magnets, especially for shunt and compound wound machines. The methods heretofore used were either based on purely theoretical deductions, and were therefore of little practical value, or else they were inaccurate or cumbersome and unreliable. The method described in these articles was devised to meet the requirements of engineering practice, and to obviate as much as possible the objectionable factor of empiricism. Although far from perfect, it will at least serve as a guide until some more complete method is devised and thoroughly tested by its application to practice. The greater part of these articles was first published in the Electrical World, ' of New York. They have, however, been revised, enlarged, and in many parts rewritten entirely.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1892 edition. Excerpt: ... CHAPTER V. Compound Machines. The general principle of the compound winding is as follows: In a simple shunt machine, the greater the current in the external circuit or in the armature, the greater will be the fall of potential in the armature itself, due to its resistance, and therefore the loss will be the difference of potential at the terminals of the shunt coils. This decreases the current in them, thus diminishing the magnetism, which again decreases the potential. The potential at the poles of the shunt machine must, therefore, fall a certain definite amount with an increase in the number of lamps in circuit. When the armature resistance is very small, this decrease of potential will be correspondingly small. The increased "countermagnetism" of the armature, due to its own current, also tends to decrease the potential for an increased current. If by some means these losses of potential, due to an increased current, could be generated again automatically by an exactly equal amount by increasing the magnetism proportionally, it is evident that the potential at the poles could be made to remain constant or nearly so. This may be done by adding series coils to such an amount that the total magnetism of the field increases with an increasing current in the external circuit, thus maintaining constant the potential at the poles of the machine. The connections of the shunt coils may be made in one of two ways. In the first of these, called the ordinary compound machine connections, and shown in Fig. 3, the terminals of the shunt coils are connected to the poles of the armature, or, what is the same thing, to the brushes. The current in the series coils is, therefore, not the total current of the armature, but is the current in the...

Excerpt from Practical Directions for Armature and Field-Magnet Winding The winding of a dynamo or motor is a matter of some difficulty (as all students of Electricity have discovered), hence many attempts otherwise successful, have ended here in failure and discouragement. The importance then of knowing how to wind a machine properly, can be seen at once. The standard works on Electricity contain very little practical information on this subject. The reason for this lack of information probably is the fact that the art of winding was to a great extent theoretical, until a very recent date. At present, although not absolutely perfect, electrical knowledge has reached a more scientific basis. By following certain rules, one may wind a machine to obtain almost any result desired. In this treatise theories have not been deeply entered into, the information being more of a practical character. It is thus adapted to the use of beginners and to the more advanced student. Illustrations have been used wherever necessary to make the text clear to the mind of the reader. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
