Practical Calculation of Dynamo-Electric Machines; A Manual for Electrical and Mechanical Engineers and a Text-Book for Students of Electrical Engineering: Continuous Current Machinery (Classic Reprin

Master practical dynamo design with this comprehensive, tables‑driven reference.

This revised and enlarged manual by Alfred E. Wiener delivers a practical approach to calculating continuous-current machines. Written for electrical and mechanical engineers and students, it emphasizes calculation methods over theory, offering proven techniques drawn from extensive real‑world data.

The book compiles hundreds of tables and nearly five hundred formulae, drawn from a wide range of dynamos used worldwide. It covers the full design process—from conductor sizing and winding layouts to field magnet frames and pole pieces—so readers can progress from basic dimensions to complete armature and magnet assemblies. The text presents measurements in both English and metric systems to fit workshop and classroom use.
Key topics are organized to support hands‑on work, with practical guidance on standard components, insulation choices, and the physical layout of armatures and cores. Descriptions of completed machines are omitted in favor of a thorough set of references, examples, and step‑by‑step calculations that reflect real design challenges.
What you’ll experience

• A practical framework for calculating armature length, size, and winding necessary for a given output and speed
• Detailed guidance on arranging conductors, selecting magnet frames, and sizing field windings
• Numerous worked examples and complete calculation methods, including leakage, efficiencies, and temperature considerations
• Clear tables for dimensions, speeds, densities, and insulation choices to support shop‑level design work

Ideal for readers who design or study continuous current dynamos, or who need a reliable, workshop‑ready reference that translates theory into practice.
