What is different between synchronous machine and Construction of Synchronous Motor Electrical4U

Jan 16 32 main difference between synchronous machines and induction machine is that synchronous machine always operates at the synchronous speed Ns=120 f/p where f is supply frequency at which the motor Mar 19 32 The 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 We will look into the construction details of the various parts one by one in detail

Types and Construction of synchronous machinesPrinciple working of Synchronous generator or Alternator

Construction of synchronous machines Salient pole Machines These type of machines have salient pole or projecting poles with concentrated field windings This type of construction is for the machines which are driven by hydraulic turbines or Diesel enginThe stator in the synchronous generator is a stationary armatureThis consists of a core and the slots to hold the armature winding similar to the armature of a dc generatorThe stator core uses a laminated constructionIt is built up of special steel stampings insulated from each other with varnish or paperThe laminated construction is basically to keep down eddy current loss

Synchronous Motors Applications And Working PrincipleWhat is the inverse construction of a synchronous machine

Jul 11 32 Application of Synchronous Motors Synchronous motor having no load connected to its shaft is used for power factor improvement Owing to its characteristics to behave at any electrical power factor it is used in power system in situations where static capacitors are expensive Synchronous motor finds application where operating speed is less around 500 rpm and high power is requiredAs I understand there is no “inverse construction” of a synchronous “machine” In electrical science and engineering a synchronous machine is a motor Synchronous motors or machines are chosen for their constant torque / speed and along with

Synchronous Generator Construction and Working PrincipleDesign of Synchronous Machine

In this article let us discuss about synchronous generator working principle Synchronous Generator The rotating and stationary parts of an electrical machine can be called as rotor and stator respectively The rotor or stator of electrical machines acts as a power producing component and Salient Pole Machine In case of salient pole machines either round or rectangular pole construction is employed In these types of machines the diameter of the machine will be quite larger than the axial length Round Poles The ratio of pole arc to pole pitch may be assumed varying between 06 to 07 and pole arc may be taken as
