There no any doubt that, the science of electric machinery is one of the necessary important sciences for the undergraduate students in electrical engineering and in mechanical engineering as well. This book "Single Phase & Special Electric Machinery" covers single-phase and most of special electric machines. Single phase motors are those to be fed from single-phase supply. Although they are less efficient when compared to 3-phase motors, they are the most familiar in use for home appliances, shops, offices etc. This is because 3-phase power was originally generated and distributed for lighting only; millions of homes were given single phase supply. Even where 3-phase mains are present, single-phase supply may be obtained from it by using one of the three lines and the neutral. On the other hand, special electric machines are those used to perform special domestic. Some of them machines find applications in computer peripheral equipment or in process control systems whereas others can be used in devices such as home appliances.

Prof. Dr. Fathe Allythi has received his PhD degree in Electrical Engineering from Al-Azhar University, Egypt, 1991G. Since then he worked in the teaching field. Now, He is a Prof. Dr. of Electrical Machines and related Courses at Al-Azhar University and Egyptian Universities. He has many publications. Most his searches are in wind energy.
