Learn how electric machines work—from the basics to practical motors that power everyday tech.
This accessible reference explains the core ideas behind dynamos and direct‑current motors, linking theory to real‑world design and control.
In clear, step‑by‑step language, this edition walks you through magnetic fields, induced currents, and the mechanisms that make motors run. You’ll see how engineers tackle issues like sparking, self‑induction, and armature reaction with topics that span from fundamental principles to advanced machine features.
- Foundational concepts: magnetic fields, flux, and the laws that govern induction.
- Motor types and behavior: series, shunt, compound, and interpole designs.
- Practical speed and voltage control methods for reliable operation.
- How components like commutators, brushes, and windings affect performance.
Ideal for readers of technical history and engineering reference, this book suits students and professionals seeking a solid grounding in DC machines and their evolution.
