In the present edition, some material of the book has been reworked and rewritten so as to make the presentation easily comprehensible. More illustrative examples mainly from IAS, IES and GATE have been added and problem material with answers, at the end of each chapter, has been considerably enlarged. With recent advances in power electronics and microelectronics, new electric machine types like brushless dc motors, variable-reluctance motors etc. are found in modern electric drive systems. Keeping these advances into consideration, An appendix, containing objective-type questions pertaining to the topics covered in this book, is given in the end. The generalized theory of electrical machines, emphasizing the basic similarities of all the machines, now forms the basis of mathematical-machine modelling.The magnetic field view-point leads to steady-state analysis, whereas the generalized approach leads only to steady-state, transient and dynamic analysis.
