Sinopsis

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.
