Hi friends in this article I am describing the synchronous generator construction and parts and hoping this article will boost your knowledge and imaginations. AC generators always run at a constant speed synchronous speed. That is why they are also known as synchronous generators.

Mar 04 2020nbsp018332Construction of Alternator. The construction of an alternator consists of field poles placed on the rotating fixture of the machine. An alternator is made up of two main parts a rotor and a stator. The rotor rotates in the stator and the field poles get projected onto the rotor body of the alternator.
Construction of Synchronous Generator. The rotor and stator are the rotating and the stationary part of the synchronous generator. They are the power generating components of the synchronous generator. The rotor has the field pole and the stator consists the armature conductor.
Basic Principles of Synchronous Machine A synchronous machine is just an electromechanical transducer which converts mechanical energy into electrical energy or vice versa. The fundamental phenomenon or law which makes these conversions possible are known as the Law of Electromagnetic Induction and Law of interaction.
A dc generator is an electrical machine which converts mechanical energy into direct current electricity. This energy conversion is based on the principle of production of dynamically induced emf. This article outlines basic construction and working of a DC generator.
Mar 19 2018nbsp018332The construction of a synchronous motor is very similar to the construction of an alternator. Both are synchronous machines where one we use as a motor and the other as a generator. Just like any other motor the synchronous motor also has a stator and a rotor.
Excitation System of Synchronous Generator. The rotor poles of a synchronous generator are electromagnets. They require excitation for their operation. The field winding needs a DC supply to produce the required flux. There are several excitation systems which are used to provide DC excitation current for the generator.
An alternator or AC generator is an electrical machine which converts mechanical energy into alternating electric energy. They are also known as synchronous generators. The working principle of an alternator or AC generator is similar to the basic working principle of a DC generator.
The stator in the synchronous generator is a stationary armature.This consists of a core and the slots to hold the armature winding similar to the armature of a d.c generator.The stator core uses a laminated construction.It is built up of special steel stampings insulated from each other with varnish or paper.The laminated construction is basically to keep down eddy current losses.
A description of the basic laws of physics governing the operation of the syn
Construction of Synchronous Generator. In general synchronous generator consists of two parts rotor and stator. The rotor part consists of field poles and stator part consists of armature conductors. The rotation of field poles in the presence of armature conductors induces an alternating voltage which results in electrical power generation.
EE 340 Spring 2011 Synchronous Generators I . Construction of synchronous machines In a synchronous generator a DC current is applied to the rotor winding producing a rotor magnetic field. The rotor is then turned by external means producing a rotating magnetic

Nov 13 2016nbsp018332Salient Pole Synchronous Generator A Salient Pole Synchronous Generator as shown in Fig. 4.29 is distinguished from a round rotor machine by constructional features of field poles which project with a large interpolar air gap.
Internal generated voltage of a synchronous generator The magnitude of internal generated voltage induced in a given stator is E N f AC 2 K where K is a constant representing the construction of the machine is flux in it and is its rotation speed.
Jan 02 2019nbsp018332Generator. The generator is an electrical device that converts mechanical energy received from the shaft into electrical energy. Normally we use induction generators in modern wind turbines. Previously synchronous generators were popular for this purpose. Permanent Magnet DC generator also used in some wind turbines.
Nov 22 2019nbsp018332The basics of synchronous machines. Two different basic designs can be separated namely round or cylindrical and salient pole. The round or cylindrical designs are used in machines operating on high speed whereas the salient pole design is used in machines operating on slow or moderate speed. The construction of a synchronous
Synchronous motor and induction motor are the most widely used types of AC motor. Construction of a synchronous motor is similar to an alternator AC generator.A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.
Synchronous motor is one of the most efficient motors. The ability to control their power factor makes it very demandable especially for low speed drives. This post will discuss Synchronous motor its construction working principle types characteristics starting methods applications model phasor diagram advantages and disadvantages.
Both are twopole synchronous generators. The primary difference between the two types is evident from looking at these two figures. The roundrotor synchronous generator has a uniform air gap which means the self
Hi friends in this article I am going to discuss about synchronous motor working principle and construction.I hope you will find it interesting and helpful. Synchronous motor construction is very similar to that of a synchronous generator. As shown in the figure essential parts of synchronous motor are same as those of the synchronous generator i.e. a stator and a rotor.
