Book description
Electrical Machine Design caters to the requirements of undergraduate and postgraduate students of electrical engineering and industry novices. The authors have adopted a flow chart based approach to explain the subject. This enables an in-depth understanding of the design of different types of electrical machines with an appropriate introduction to basic design considerations and the magnetic circuits involved. The book aids students to prepare for various competitive exams through objective questions, worked-out examples and review questions in increasing order of difficulty. MATLAB and C programs and Finite Element simulations using Motor Solve, featured in the text offers a profound new perspective in understanding of automated design of electrical machines.Table of contents
