FIG. 87. — Multiple double re-entrant drum full pitch winding. 174 ELEMENTS OF ELECTRICAL ENGINEERING Figs. 88 and 89. Fig. 88 shows a part of a series drum winding developed. Coils C\ and C2, having corresponding positions under poles of equal polarity, are joined in series. Thus the end con- nection ah of coil Ci connects by cross connection be and cd to the FIG. 88. — Series lap winding. end connection de of coil C%.

This has the effect that the coils are apparently open at one side. Such a winding has been called a wave winding. Only series windings with a single turn per coil ...Chapter-Local Concept Hits

Modern Engineering Reading Prompts
Section titled “Modern Engineering Reading Prompts”- Waves / transmission lines: Map Steinmetz’s wave and line language onto modern distributed constants, propagation velocity, standing waves, and reflections.
Ether-Field Interpretive Boundary
Section titled “Ether-Field Interpretive Boundary”- Waves / transmission lines: Standing/traveling wave passages may support richer field interpretations; the page keeps those readings separate from verified Steinmetz wording.
Promotion Checklist
Section titled “Promotion Checklist”- Open the full source text and the scan or raw PDF.
- Verify the chapter boundary and surrounding context.
- Promote exact quotations only after checking the source image.
- Move mathematical candidates into canonical equation pages only after formula typography is corrected.
- Move diagram candidates into the diagram archive only after image extraction, crop verification, and manifest creation.
- Keep Steinmetz wording, modern translation, and ether-field interpretation in separate labeled layers.
