Synopsis

You can recite the torque equation. You still cannot turn a 200 kW, 400 V, 1485 rpm nameplate into a bore diameter and stack length that works. This book closes that gap.

A graduate-level, computationally driven treatment of electrical machine design. Each chapter pairs full field-theoretic derivation with runnable Python sizing code verified against closed-form checks. Every method arrives with both a derivation and a working tool that reproduces it across induction, synchronous, permanent-magnet, DC, and reluctance machines.

WHAT’S INSIDE

• Electromagnetic foundations, including Maxwell’s equations, the Lorentz force law, and five torque-extraction methods.

• Windings and current linkage, including distribution factors, pitch factors, harmonic suppression, and star-of-slots construction.

• Magnetic circuits, leakage, and resistance, including Carter’s factor, magnetization curves, leakage inductance, and skin-effect resistance.

• Main dimensions and computational sizing using a coupled electromagnetic, thermal, and mechanical Python workflow.

• Complete induction-machine design, from equivalent circuits and slot selection to a fully sized cage-rotor motor.

• Variable-frequency drives, traction operation, doubly-fed generators, and drive-cycle efficiency mapping.

• Synchronous-machine design, including load-angle behavior, test curves, damper windings, and a complete salient-pole generator design.

• Permanent-magnet machine design, including demagnetization limits, rotor topologies, d-q inductances, saliency, and cogging-torque mitigation.

• EV traction motor design with field weakening and a 4,000-design computational sweep across power density, efficiency, and cost.

• DC machine design, commutation, armature reaction, commutating poles, and compensating windings.

• Switched and synchronous reluctance machines, converter operation, current control, and torque-ripple mitigation.

• Insulation and thermal design using Arrhenius life models and lumped-parameter thermal circuits.

WHAT YOU WILL LEARN TO DO

• Size a machine directly from its power, voltage, and speed specifications.

• Derive equivalent-circuit parameters from physical geometry.

• Calculate leakage inductance and AC copper losses.

• Design a permanent-magnet rotor against demagnetization and saliency limits.

• Build a coupled electromagnetic, thermal, and mechanical sizing program.

• Sweep thousands of candidate designs using Python.

• Predict torque-speed behavior under variable-frequency drive supply.

WHY THIS BOOK

• Every sizing method includes runnable Python code.

• Permanent-magnet traction design receives full chapter-length coverage.

• Leakage, skin effect, insulation, and thermal design receive detailed treatment.

• 83 worked examples and 225 solved problems follow one consistent six-part method.

• One notation system and figure style extends across every machine type.

WHO THIS BOOK IS FOR

Graduate students taking electrical-machine design courses and practicing engineers moving from machine analysis into practical sizing, especially those working in EV traction and industrial-drive programs.

A machine sized incorrectly is expensive to learn about after the prototype is built. This book puts that mistake on paper, and in Python, first.
