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. Note: Theoretically, a DC generator can be used as a DC motor without any constructional changes and vice versa is also possible.

Working Principle of DC Motor

A DC Generator is an electrical device which converts mechanical energy into electrical energy. It mainly consists of three main parts, i. The other parts of a DC Generator are magnetic frame and yoke, pole core and pole shoes, field or exciting coils, armature core and windings, brushes, end housings, bearings and shafts. The Magnetic Field System is the stationary or fixed part of the machine. It produces the main magnetic flux. These various parts of DC Generator are described below in detail. The outer hollow cylindrical frame to which main poles and inter-poles are fixed and by means of which the machine is fixed to the foundation is known as Yoke.

What Are the Functions of Parts in an Electric Motor?

A DC motor is any of a class of rotary electrical motors 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 internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor. DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor's speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings.

Each DC machine contains two separate terminals with a magnetized center between them. There are two main parts, the stator and the rotor. The stator contains parts such as brushes, magnets and housing for the whole motor. The rotor contains the windings, the communicator and the output shaft. The two parts work together when voltage is applied to create a moving motor. DC motors work in two directions. A DC machine that produces electricity by consuming mechanical energy is a generator.

In any electric motor, operation is based on simple electromagnetism. A current -carrying conductor generates a magnetic field; when this is then placed in an external magnetic field, it will experience a force proportional to the current in the conductor, and to the strength of the external magnetic field. As you are well aware of from playing with magnets as a kid, opposite North and South polarities attract, while like polarities North and North, South and South repel. The internal configuration of a DC motor is designed to harness the magnetic interaction between a current -carrying conductor and an external magnetic field to generate rotational motion. Let's start by looking at a simple 2-pole DC electric motor here red represents a magnet or winding with a "North" polarization, while green represents a magnet or winding with a "South" polarization. Every DC motor has six basic parts -- axle, rotor a. In most common DC motors and all that BEAM ers will see , the external magnetic field is produced by high-strength permanent magnets 1.


What are DC Motor Parts and how they work? Stator. A stator is one of the DC motor parts that is, as the name suggests, a static unit containing the field windings. Rotor. Yoke. Poles. Field Windings. Armature Windings. DC Motor Commutator. Brushes.

Facebook Twitter. Want to know what is an electrical dc motor. It is an electrical machine which converts electrical energy into mechanical energy. This electric dc motors can be operated by giving both AC current and DC current.

The conversion of this mechanism is known as the commutator, thus these machines are also named as commutating machines. DC machine is most frequently used for a motor. The main benefits of this machine include torque regulation as well as easy speed. The applications of the DC machine is limited to trains, mills, and mines.

Интересно. А что по этому поводу думает Энсей Танкадо. - Я ничем не обязан мистеру Танкадо. Он зря мне доверился.

 - Где его вещи. - Alli, - ответил лейтенант с желтыми прокуренными зубами. Он показал на прилавок, где лежала одежда и другие личные вещи покойного.

Она зажмурилась. - Попробую угадать. Безвкусное золотое кольцо с надписью по-латыни.

 Успокойся, Сьюзан, - сказал Стратмор, положив руку ей на плечо. Это умиротворяющее прикосновение вывело Сьюзан из оцепенения. Внезапно она вспомнила, зачем искала Стратмора, и повернулась к. - Коммандер. Северная Дакота - это Грег Хейл.

 - Позволь мне объяснить.  - Голос его, однако, мягче не.  - Во-первых, у нас есть фильтр, именуемый Сквозь строй, - он не пропустит ни один вирус. Во-вторых, если вырубилось электричество, то это проблема электрооборудования, а не компьютерных программ: вирусы не отключают питание, они охотятся за программами и информацией.

 Где она? - Сердце Беккера неистово колотилось. - Пошел к черту.

 Прошу прощения. - Шекспир, - уточнил Хейл.  - Гамлет.
