Synopsis

A thorough, historically rooted guide to designing direct and alternating current machines, with practical methods you can apply today.

This edition presents a course of lectures on Electrical Machine Design, outlining how to size and specify direct-current machines, alternators, synchronous motors, polyphase induction motors, and transformers. It emphasizes building up a design from a few fundamental formulas and constants, with clear guidance on when and how to adjust for real-world limits. The text blends theory with hands-on design steps, making it a reliable reference for students and practicing engineers alike.

Readers will find a systematic approach to machine design, including how to evaluate magnetic circuits, armature winding arrangements, insulation, losses, heating, and efficiency. The work also discusses practical considerations such as heat management, frame dimensions, air gaps, and assembly details, all grounded in long-standing engineering experience.

  • Foundational formulas and design constants used to size machines for given ratings.
  • Step-by-step guidance on armature and field system design, with examples and calculation methods.
  • Discussion of performance factors like efficiency, losses, heating, and regulation.
  • Coverage of construction, insulation, and practical constraints for DC and AC machines.

Ideal for readers of engineering texts who want a solid, methodical reference to both the theory and practice of electrical machine design.
