If you give electrical input then it will give mechanical output. Basically, a DC generator can be used as a DC motor as well. That is why they are commonly known as DC machine.
Aug 26, 2020 Construction of DC Generator - Each Part Explanation. Electricity generated at all the power plants is alternating i.e., ac, in order to generate direct current i.e., dc, a commutator is used to convert the generated ac supply into dc supply. Hence, an electrical generator with a commutator fixed on the shaft is known as a DC Generator.

Nov 27, 2020 Construction of DC generator Working Principle of DC generator. A simple DC generator consists of a coil of insulated copper wire. The coil is placed between the two poles of a strong horseshoe magnet. In actual practice, a large number of turns
The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. Any dc generator can be run as a dc motor and vice-versa. Read Working of DC Motor. All dc machines have five principal components.
Feb 24, 2012 But for large construction of DC generator, where weight of the machine is concerned, lighter cast steel or rolled steel is preferable for constructing yoke of DC generator. Normally larger yokes are formed by rounding a rectangular steel slab and the edges are welded together at the bottom. Then feet, terminal box and hangers are welded to the ...
Jul 25, 2017 Construction. The basic constructions of DC tachogenerator are shown in fig. The dc tachogenerator is a small dc generator. The armature is driven by motor shaft whose speed is feedback. The rotor iron cored and field is a permanent magnet. The armature of a dc tachogenerator is of similar to design to that of conventional dc motor.
Nov 26, 2020 DC Generator construction. The construction of a DC generator is similar to a DC motor. So, a DC generator can work as a DC motor and vice-versa. The basic constructional features of a DC generator are described below. YOKE The yoke is the outer covering of the DC generator and is made of cast steel or cast iron. It serves two purposes
Mar 21, 2021 Construction of the DC Generator The DC generator is constructed by keeping the two conductors A B and C D between two magnets both these conductors are connected to the commutator and the brushes are mounted on the surface of these commutators to which the external circuit is connected. Whenever the conductors cut the magnetic flux lines the EMF is induced that causes the
Apr 13, 2019 Construction. A DC generator is also used as a DC motor without changing its construction. Therefore, a DC motor otherwise a DC generator can be generally called a DC machine. The construction of a 4-pole DC generator is shown below. This generator comprises of several parts like yoke, poles amp pole shoes, field winding, an armature core, armature winding, commutator amp brushes.
Jul 02, 2020 1. Separately Excited Generator. 5.2. 2. Self-excited Generator. 6. Applications of D.C. Generators. An electrical DC generator is a machine which turns mechanical energy into electrical energy. Or in other words it is a machine which converts mechanical energy into a direct current.
U1.3 Construction of DC Generators The parts of a simple DC generator are shown in fig.1.3. The principle of operation of a DC generator is similar to that of the AC generator, which was discussed previously. A rotating armature coil passes through a magnetic field that develops between the north and

An AC generator is a device that converts mechanical energy into alternating electrical energy for appropriate use. Based on the type of power input, there are two types of generators AC generator and DC generator.Slip rings are used in AC generators to produce alternating current, while direct current is used in DC generators.
Jun 07, 2020 A DC generator is often used as a DC generator motor without altering its construction. So, a dc generator motor may usually be called a DC machine. The key parts of DC generators are yoke, poles, pole shoes, armature core, armature winding, commutator, brushes, magnetic field system, commutator, end housings, bearings, and Shafts.
DC generators produce direct current and are typically found on light aircraft.
