Oct 13, 2016· ROTOR • The Rotor is the moving part of a D.C. generator. • The rotor rotates because the wires and magnetic field of the motor are arranged so that a torque is developed about the rotor's axis. 12. WORKING of DC GENERATOR 13. • The Dc Generator Converts Mechanical Energy into Electrical Energy.
The rotor is a rotating electromagnet that requires a DC ( Direct Current) electric power source to excite the magnetic field. This power comes from an exciter. DC Exciter. In the past, the exciter was a small DC generator coupled to the same shaft as the rotor. Therefore, when the rotor rotates this exciter produces the power for the ...
Direct current is a bit easier to understand than alternating current. Rather than oscillating back and forth, DC provides a constant voltage or current. Generating DC DC can be generated in a number of ways: An AC generator equipped with a device called a"commutator" can produce direct current Use of a device called a"rectifier" that converts ...
Sep 08, 2019· No Load Saturation Characteristics of a Separately Excited DC Generator. Here, we measure the terminal voltage of a no-load separately excited dc generator for various fields currents. We control the field current by a rheostat connected in the field system as shown in the figure below.
Brushless DC motors (BLDC) have been a much focused area for numerous motor manufacturers as these motors are increasingly the preferred choice in many applications, especially in the field of motor control technology. BLDC motors are superior to brushed DC motors in many ways, such as ability to operate at high speeds, high efficiency, and better heat dissipation.
Mar 29, 2019· DC motor construction parts. A DC motor is composed of the following main parts: Field coil or stator. This is a non-moving part of the magnetic circuit on which a winding is wound in order to produce a magnetic field. The electro-magnet that is created has a cylindrical cavity between its poles. Armature or rotor
Oct 05, 2016· Direct current or DC machines are used for the conversion of one form of energy to another. Similarly a DC Generator is used to generate the energy which works on the principle of converting mechanical energy into electrical energy. Basic law or principle behind the generator is the Faraday's law of electromagnetic induction which states that whenever a conductor is moved in the .
Jul 28, 2015· A.C. generators or alternators (as they are usually called) operate on the same fundamental principles of electromagnetic induction as D.C. generators. Alternating voltage may be generated by rotating a coil in the magnetic field or by rotating a magnetic field within a stationary coil.
Module 2 - Basic DC Theory This module describes the basic concepts of direct current (DC) electrical circuits and discusses the associated terminology. Volume 2 of 4 Module 3 - DC Circuits This module introduces the rules associated with the reactive components of inductance and capacitance and how they affect DC circuits. Module 4 - Batteries
Jan 24, 2018· Introduction An electrical circuit is a complete conductive path through which electrons flow from the source to the load and back to the source. The direction and magnitude of the electrons flow however depend on the kind of source. In Electrical Engineering, there are basically two types of voltage or current (Electrical Energy) source which defines the kind of circuit and they are ...

DC Generator. 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.. Construction of a DC .
Sep 14, 2019· An Electrical Generator is a machine that converts mechanical energy into electrical energy. This machine is further classified into two other kinds based on the power supply i,e ac and dc. The basic difference name a generator as an ac or dc is its input power supply.

Jan 13, 2019· Before we can explain the working principle of a DC generator, we need to cover the basics of generators.. There are two types of generators – DC generators and AC generators. Both DC and AC generators convert mechanical power to electrical power.A DC generator produces direct power, while an AC generator produces alternating power.
Just like a DC Machine, a same induction machine can be used as an induction motor as well as an induction generator, without any internal modifications.Induction generators are also called as asynchronous generators. Before starting to explain how an induction (asynchronous) generator works, I assume that you know the working principle of an induction motor.
Categories Alternator, DC Generator, Electrical Machines, Generation, Power System The machine which produces 3 phase power from mechanical power is called an alternator or synchronous generator. The working of an alternator is based on the principle that when the flux linking a conductor changes, an emf is induced in the conductor.

Direct Current (DC) voltage. Batteries and DC generators produce DC voltage. Alternating current: With this method, voltage forces electrons to flow first in one direction, then in the opposite direction, alternating very quickly. This type of voltage is called Alternating Current (AC) voltage. A generator is used to produce AC voltage.
