A concise guide to understanding alternating currents in electrical machines that students can apply from day one.
This volume is the second part of a notes-style course intended for a three-term study of alternating currents. It aims to present the main principles clearly so a reader can proceed to more detailed works on design.
The text frames the subject with practical explanations and a steady progression from basic concepts to more complex topics. It emphasizes how theory connects to measurement, design decisions, and testing scenarios, making the material useful for classroom study and lab work alike.
- How an alternating electromotive force is produced and how field forms shape the output
- The role of sine-field form, harmonics, and field form factors in practical machines
- Ways to arrange windings, calculate voltages, and relate mechanical speed to electrical frequency
- Methods for predicting excitation needs and regulating output under load
- Techniques for evaluating efficiency, losses, and regulation in large machines
Ideal for students of electrical engineering, technologists, and professionals seeking a clear, test-ready reference to alternating currents and machine behavior.
