{ "item_title" : "Rotating Electrical Machine Design", "item_author" : [" Matthias K. R. Wenzel "], "item_description" : "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 FORGraduate 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.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/9/79/819/335/9798193353225_b.jpg", "price_data" : { "retail_price" : "108.00", "online_price" : "108.00", "our_price" : "108.00", "club_price" : "108.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
