The author explains the different types of AC machines, such as synchronous machines, induction machines, and asynchronous machines. He also discusses the various methods of speed control, such as frequency control, voltage control, and power electronic control.
The primary textbook by V.K. Mehta and Rohit Mehta for this subject is Principles of Electrical Machines
Transformers are static machines that transfer energy between two or more circuits through electromagnetic induction. V.K. Mehta's book provides a detailed coverage of transformers, including their construction, working principles, and applications.
AC machines, also known as alternating current machines, are widely used in applications such as motor drives, generators, and power transmission systems. V.K. Mehta's book provides a comprehensive coverage of AC machines, including their construction, working principles, and characteristics.
