Theory and Calculation of Electric Apparatus
This scan is the verification base for motor, transformer, regulation, heating, harmonic, and apparatus-loss passages.
sources/theory-calculation-electric-apparatus/ This is one of the most important next sources for the archive. It connects Steinmetz’s mathematical AC theory to machines, transformers, induction motors, regulation, losses, heating, and practical apparatus design.

processed/theory-calculation-electric-apparatus/cleaned_text/internet-archive-ocr.txt.The first generated chapter candidates include:
| No. | Candidate Chapter | Research Value |
|---|---|---|
| I | Speed Control of Induction Motors | Motor speed, slip, regulation, and torque. |
| II | Multiple Squirrel-Cage Induction Motor | Connects directly to Steinmetz induction-motor patent themes. |
| IV | Induction Motor with Secondary Excitation | Secondary excitation and phase/motor behavior. |
| V | Single-Phase Induction Motor | Single-phase motor theory and apparatus comparison. |
| VI | Induction-Motor Regulation and Stability | Stability, regulation, and operating behavior. |
| VII | Higher Harmonics in Induction Motors | Harmonics and wave-shape effects in apparatus. |
The immediate research task is to scan-check the chapter map, correct OCR heading defects, extract original apparatus figures, and promote induction-motor and transformer equations into the mathematics section.
Generated source dashboard: this section joins the source overview to the book coverage atlas, source text reader, chapter workbench, visual maps, and formula maps. Counts are candidate research aids until scan verification promotes them.

Theory and Calculation of Electric Apparatus currently contributes 22 processed sections and 118,262 candidate OCR/PDF-text words to the archive. Its strongest tracked evidence clusters are Magnetism, Field language, Radiation / light.
This is a routing judgment based on processed metadata, not a final historical claim. The strongest next move for any exact quotation, equation, or diagram is still to open the source scan and check the page image.

Verify title page, edition, page images, and OCR line boundaries before final quotation.
Use the formula map to locate equations, then correct OCR symbols and preserve Steinmetz notation before modern translation.
Modern engineering and ether-field readings belong after source anchoring, with labels kept visible.
