The main focus of this course is to understand the magnetic field, the reluctance of magnetic materials and air. The voltage-current characteristics, voltage regulation of DC generators, torque speed characteristics, speed regulation of DC motors and the generalized concepts of electromechanical energy conversion are included mainly in this course. Working principles, construction and operation of single phase and three phase transformers will be studied. This course includes AC machines fundamentals and production of rotating magnetic field. In this course working principles, construction, characteristics and equivalent circuit of three phase synchronous generators, synchronous motors and induction motors. Basics of linear motor will be studied. Understanding of three phase power system. Contemporary issues related to electrical power system will be discussed.
