Answering Seven Common Questions on Generator and Motor

Brush wear comes from two basic causes mechanical friction and electrical wear A rotating magnetic field is one whose north and south poles move inside the stator An induction generator is identical in construction to an induction motor

Construction of a Synchronous Machine Circuit

The rotating part of the machine is called Rotor There are two types of rotor construction namely the salient pole type and the cylindrical rotor type

Alternator Wikipedia

An alternator is an electrical generator that converts mechanical energy to electrical energy in Alternating current generating systems were known in simple forms from the discovery of the magnetic induction of The rotor comprised two intermeshed six pole quot claws quot welded to and spaced apart by a non magnetic ring

Rotor electric Wikipedia

The rotor is a moving component of an electromagnetic system in the electric motor electric generator or alternator Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor 39 s axis Contents hide 1 Early development 2 Type and construction of rotors The rotor is a large magnet with poles constructed of steel lamination

Synchronous motor theory of operation and its

15 Jul 2009 Do you know that the Synchronous motors work on a unique theory of Motor easily let us consider only two poles in the stator and rotor

Synchronous motor construction and working

The construction of a synchronous motor is as shown in the figure Consider a two pole synchronous machine as shown in figure below working of

Working of a 2 pole DC Motor YouTube

9 Jul 2013 DC motor is designed to convert DC electrical energy into mechanical energy The current makes the wire behave like an electromagnet

Differentiating Between DC and AC Motors Electrical

If you think about the attraction and repulsion of the north and south poles of a bar magnet you 39 re on your way to Let 39 s learn the basics of both types of motors Fig 2 The series DC motor has the field winding in series with the armature

DC Motors principles of operation

Let 39 s start by looking at a simple 2 pole DC electric motor here red Every DC motor has six basic parts axle rotor a k a armature stator Iron core construction is also relatively inexpensive compared with other construction types

Synchronous Motor Working Principle

Now let us first go through the basic construction of this type of motor Synchronous motor is a doubly excited machine i e two electrical inputs are provided to it motor is of salient pole type additional winding is placed in rotor pole face

Field coil Wikipedia

A field coil is an electromagnet used to generate a magnetic field in an electro magnetic machine typically a rotating electrical machine such as a motor or generator It consists of a coil of wire through which a current flows In a rotating machine the field coils are wound on an iron magnetic core For this reason when machines must use two sets of windings the windings

Basic construction and working of a DC Generator

The above figure shows the constructional details of a simple 4 pole DC machine A DC machine consists two basic parts stator and rotor Basic constructional

Construction of a DC Machine And working of dc

Each pole is divided into two parts namely I Pole core and II Pole shoe This is shown in the Fig 2 basic construction of dc machines commutation of dc

Electric motor Wikipedia

An electric motor is an electrical machine that converts electrical energy into mechanical Electric machines come in two basic magnet field pole configurations rapid acceleration these motors have a rotor that is constructed without any

AC Motor Basic Stator and Rotor Operation

An AC motor has two basic electrical parts a quot stator quot and a quot rotor quot as shown in As shown in Figure 9 the stator has six magnetic poles and the rotor has two

Generalized theory of mixed pole machines with a general

A simple representation is also presented from which the machine d–q model can be The mixed pole machine MPM is two electrically connected and A new rotor construction that combines the features of both a reluctance and cage

4 answers What is the difference between a salient pole

We use a cylindrical rotor or a salient pole rotor in a synchronous machines Cylindrical rotor There are mainly two types of Synchronous Generator from rotor construction point of view The two main types of synchronous machine are
