Difference between Synchronous Motor and Induction Motor
A motor in general is an electrical machine that converts electrical energy into mechanical energy. Electric motors can either be DC Motors or AC Motors, depending on the type of power supply that is supplied as its input.AC motors are further classified into two types−Asynchronous or Induction MotorSynchronous MotorA synchronous motor always runs at synchronous speed, while an induction motor runs at a speed less than the synchronous speed.Read through this article to find out more about synchronous motors and induction motors and how they are different from each other.What is a Synchronous Motor?A synchronous motor is a type of ...
Read MoreTesting of Transformer | Type Tests, Routine Tests and Special Tests of Transformer
An electrical transformer is tested at the transformer manufacturer premises and at the consumer’s site and also periodically in regular and emergency basis during its service life to confirm its specifications and performance.Types of Transformer TestsTests of transformer done at the manufacturer’s premises −Type testsRoutine testsSpecial testsTests of transformer done at the consumer’s site −Pre-commissioning testsPeriodic testsEmergency testsType Tests of TransformerThe type tests of a transformer are performed at the manufacturer’s premises to prove the design expectations and consumer’s specifications. The type tests are performed in a prototype unit, not in all manufactured units and these tests confirm the basic ...
Read MoreCooling Methods of a Transformer
When the transformer is in operation, heat is generated due to copper losses in the windings and iron losses in the core. The removal of heat from the transformer is known as cooling of the transformer.Transformer Cooling MethodsFor the dry type transformersAir Natural (AN) CoolingAir Forced (AF) or Air Blast (AB) CoolingFor oil immersed type transformersOil Natural Air Natural (ONAN) CoolingOil Natural Air Forced (ONAF) CoolingOil Forced Air Forced (OFAF) CoolingOil Forced Water Forced (OFWF) CoolingAir Natural (AN) CoolingThe air natural (AN) cooling is used in dry type, self-cooled transformers. In this method, the natural circulation of surrounding air is ...
Read MoreDouble Revolving Field Theory of Single-Phase Induction Motors
Operating Principle of Single-phase Induction MotorA single-phase induction motor consists of a squirrel cage rotor and a stator carrying a single-phase winding. When a single-phase AC supply is fed to the stator winding, a pulsating magnetic field (not the rotating) is produced. Under these conditions, the rotor does not rotate due to inertia. Hence, a single-phase induction motor is inherently not self-starting, but requires some auxiliary starting means.If the stator winding of a single-phase induction motor is excited and the rotor is rotated by an auxiliary means and the starting device is then removed, the motor continues to rotate in ...
Read MoreCurrent Divider Rule and Voltage Divider Rule
Electric circuits are classified into two main types namely series circuit and parallel circuit based on the arrangement of components in the circuit. A series circuit is one in which the components are chain connected, while a parallel circuit is one in which all the circuit components are connected between two common points. Series circuits and parallel circuits act as voltage divider circuits and current divider circuits, respectively. Read through this article to find out more about Current Division Rule and Voltage Division Rule. Current Division Rule A parallel circuit acts as a current divider as it divides the total ...
Read MoreDifference between Conductor, Semiconductor, and Insulator
In order to differentiate the Conductor, Semiconductor, and Insulator, first we have to understand their extent of forbidden band i.e. separation between their conduction and valance band. The main difference between the conductor, semiconductor and insulator is in their conductivity.ConductorA conductor is a type of material that allows the electric current to flow through it i.e. it possesses least resistance in the path of free electrons. In case of conductor, the valance and conduction bands overlap. Due to this overlapping, a small potential difference across a conductor causes the free electrons to constitute electric current.All the metals are conductors. The ...
Read MoreHow to Find the Text on Page in ElectronJS?
Overview A find text on a page is a feature which helps a user to find a word on the page. An electronJs is an open source framework which creates a desktop application which can run on every operating system with its cross platform compatibility. The electronJs has many predefined instance methods with their respective functionality. So to build this feature of find text on page the electronJs provides a "findInPage" method which takes the current focused window and scans all the text on the page. Syntax For finding the text on page, the electronJs provides the below Syntax for ...
Read MoreDifference Between Crystal and Resonator
Crystals and resonators are used as timing devices in electronics to generate precise and reliable signals for a variety of applications. Although they perform some of the same tasks, they differ in terms of construction, characteristics, and applications. Crystals are made of piezoelectric material and vibrate at a given frequency, whereas resonators are made of a coil and capacitor and generate a resonant circuit that oscillates at a specific frequency. Read this article to find out more about Crystal and Resonator and how they are different from each other. What are Crystals? When an electrical voltage is supplied to a ...
Read MoreDifference Between Electron Geometry and Molecular Geometry
Electron geometry and molecular geometry are two concepts that are important in the field of chemistry. These concepts are related to the arrangement of atoms in a molecule and the distribution of electrons around those atoms. Although these terms sound similar, there are fundamental differences between them that are important to understand. What is Electron Geometry? The term electron geometry refers to the name of the geometry of the electron pair/groups/domains on the central atom, whether they are bonding electrons or non-bonding electrons. Electron pairs are defined as electrons in pairs or bonds, lone pairs, or sometimes a single unpaired ...
Read MoreDifference Between AFM and STM
Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM) are two very efficient techniques for examining materials at the atomic and molecular levels. AFM works on the interaction forces between the tip and the sample surface. STM is a sort of microscopy that scans the surface of a sample using a conductive tip. While AFM and STM have certain commonalities, they also have some substantial differences. Read this article to find out more about AFM and STM and how they are different from each other. What is AFM? AFM works on the interaction forces between the tip and the sample ...
