The book's enduring value lies in its comprehensive coverage of the entire design process, from core principles to advanced computer-aided techniques. The following chapter structure, based on the 2005 edition, provides a clear roadmap of its contents:
The text provides a comprehensive workflow for Direct Current (DC) machinery, focusing on: Output equations relating power to armature dimensions (
: It includes empirical data charts, such as permissible current densities and standard insulation thicknesses, saving engineers from looking through separate data handbooks.
: Understanding temperature rise limits, ventilation methods, and types of enclosures.
Design of Electrical Machines provides a systematic approach to the factors, limitations, and standard procedures involved in designing electrical apparatus. The book balances classical design principles with modern industrial requirements, making it an excellent resource for academic curricula and competitive examinations.

Derivation of the volt-ampere (VA) output based on window area and core area.
Comprehensive overview of materials used—conducting materials, magnetic materials, and insulating materials.
Designing the main poles, commutating poles (interpoles), and field coils.
Most technical universities provide digital access or physical copies through their libraries. Many have integrated e-library systems where scanned or digital versions are hosted legally for students. The book's enduring value lies in its comprehensive
For professionals seeking a deep conceptual grasp or students utilizing university reference copies, understanding the core themes of this text is essential. Key Text Details Design of Electrical Machines
While Mittle teaches classical analytical design methods, modern engineering relies heavily on Finite Element Method (FEM) software (like ANSYS Maxwell or JMAG). Use Mittle’s formulas to create a "rough cut" initial design, then understand that FEM is used in industry to optimize that design.

Calculating rotor bar and end-ring currents for squirrel cage motors, or rotor windings for slip-ring motors. Design of Electrical Machines provides a systematic approach
Induction motors are the workhorses of modern industry. The textbook emphasizes:
Stator design, including slot selection and winding layout to minimize harmonics.
The textbook serves as a comprehensive guide to the classical design methodologies of electrical apparatus. While modern engineering heavily relies on Computer-Aided Design (CAD) and Finite Element Analysis (FEA) software, Mittle’s work focuses on the analytical and empirical formulas that form the bedrock of these modern tools.
Methods of cooling, ventilation, and limits on temperature rise to prevent insulation failure. B. Design of Transformers
