A: Venkataratnam’s book is more advanced (PhD level). Janardanan is for undergraduate engineering. For PDFs, start with Janardanan.
This is a standout feature of the book. Janardanan includes a chapter on PMAF machines, a topic not available in other Indian authors' textbooks. These "pancake" motors have a unique flat design that makes them ideal for applications where space is constrained, such as in-wheel motors for electric vehicles. Special Electrical Machines E.g.
