Introduction to AC Machines Classification of AC Rotating Machines Synchronous Machines Synchronous Generators A primary source of electrical energy. Synchronous Motors Used as motors as well as power factor compensators synchronous condensers . Asynchronous Induction Machines Induction Motors Most widely used electrical motors in both domestic and industrial applications. Induction Generators Due to lack of a separate field excitation these machines are rarely used as generators. Energy Conversion Generators convert mechanical energy to electric energy. Motors convert electric energy to mechanical energy. The construction of motors and generators are similar. Every generator can operate as a motor and vice versa. The energy or power balance is - Generator Mechanical power electric power losses - Motor Electric Power Mechanical Power losses. 2 Introduction to AC Machines Dr. Suad Ibrahim Shahl AC winding design The windings used in rotating electrical machines can be classified as Concentrated Windings All the winding turns are wound together in series to form one multi-turn coil All the turns have the same magnetic axis Examples of concentrated winding are - field windings for salient-pole synchronous machines - . machines - Primary and secondary windings of a transformer Distributed Windings All the winding turns are arranged in several full-pitch or fractional-pitch coils These coils are then housed in the slots spread around the air-gap periphery to form phase or commutator winding Examples of distributed winding are -
