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
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 machine:
DC Machine Construction of DC Machine. The construction of DC machine can be done using some of the essential parts like Yoke, Pole core & pole shoes, Pole coil & field coil, Armature core, Armature winding otherwise conductor, commutator, brushes & bearings.
Construction of a DC Generator A DC Generator is an electrical device which converts mechanical energy into electrical energy. It mainly consists of three main parts, i.e. Magnetic field system, Armature and Commutator and Brush gear.
Therefore, a DC motor otherwise a DC generator can be generally called as a DC machine. The construction of a 4-pole DC generator is shown below. This generator comprises of several parts like yoke, poles & pole shoes, field winding, an armature core, armature winding, commutator & brushes.
Construction of Dc motor. Construction of Dc motor nearly looks like the construction of Dc generator, originally when the Dc machine starts working we can’t identify whether it’s a Dc generator or motor, briefly Dc motor consists of:. Stator: it’s the stationary part containing the field winding and receives the supply. Rotor: which is the rotating part.
A stator is the static part of the DC machine that houses the field windings and receives the supply. A rotor is the rotating part of the DC machine that brings about the mechanical rotations. All these parts put together make up the total construction of a DC motor.
Construction of DC Machine. A DC machine consists of two main components: Stator and Rotor. Stator is the stationary part whereas rotor is the rotating part. Stator of DC machine consists of Yoke, Field Winding, Interpoles, Compensating Winding, Brushes and End Cover. Rotor consists of armature core, armature winding, commutator and shaft. A ...

8 DC Machines Construction The poles are mounted on an iron core that provides a closed magnetic circuit. The motor housing supports the iron core, the brushes and the bearings. The rotor has a ring-shaped laminated iron core with slots.
Construction of dc Machines: The rotor in a dc machine is called an armature. The armature has cylindrical steel core that is composed of a stack of slotted laminations. Slots in laminations are aligned axially along rotor or shaft. Armature windings are placed in slots. The stator in a dc machine is the field part of the machine.
Construction. It consists of a frame called the Yoke, pole core, armature core, armature windings, commutator, brushes, and bearings. The yoke is the outer part of the machine that is used for protecting it against environmental issues. Hence, protecting shield for the machine. It is also used as a mechanical support for the pole core.
Because the AC machines have more advantages compared to that of DC machines. In this article, we shall discuss what is AC motor, construction, working principle, types, speed control, and applications. AC Motor. The machine that turns the class of input electrical form to an output mechanical form.
The DC motor was the mainstay of electric traction drives on both electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. The introduction of DC motors and an electrical grid system to run machinery starting in the 1870s started a new second Industrial Revolution.

DC MACHINES • In DC machines, the field winding is wound onto the stator, while the armature winding is located on the rotor. • Current is supplied to the rotating armature winding through Commutator Segments. • Each commutator segment (also located on the …
Nevertheless, an understanding of DC generator is important because it represents a logical introduction to the behavior of DC motors. In this chapter, we shall deal with various aspects of DC generators. Principle of operation of DC Generator-An electrical generator is a machine that converts mechanical energy into electrical energy.
A DC Motor like we all know is a device that deals in the conversion of Electrical energy to mechanical energy and this is essentially brought about by two major parts required for the construction of dc …
11-4-2019· Construction •Core of these poles are made from silicon steel on which insulated copper wire is wound to make windings. •These poles are bolted and fixed inside the frame. Core 7. Construction • When DC current is pass through the windings it creates a static magnetic field. • There are two types of pole in a DC machine. 1.
Construction of a BLDC Motor. A commutator-brushes arrangement helps in achieving unidirectional torque in a typical dc motor. Obviously, commutator and brush arrangement is eliminated in a brushless dc motor. Here, an integrated inverter/switching circuit is used to achieve unidirectional torque.
A DC motor is any of a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some interna...
10-2-2019· There is no basic difference in the construction of a DC generator and a DC motor.. In fact, the same DC machine can be used interchangeably as a generator or as a motor. Like generators, there are different types of DC motors which are also classified into shunt-wound, series-wound and compound-wound dc motors.. DC motors are seldom used in ordinary applications because all …
