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. For example, underground subway cars, as well as trolleys, may utilize DC motors. In the past, automobiles were designed with DC dynamos for charging their batteries.
Motor components are classified into five main portions 1 to 5 as Fig. Of these components, the parts most closely related to the basic classification method for motors are the stator and the rotor. The following four types are listed as the typical stator structure:. In the following Section 1. The following is a summary of nominal designations for the stator and the rotor in different languages. Wire is the material the current travels through. The wire is also called a conductor.
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.
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. These basic constructional details are also valid for the construction of a DC motor. Hence, let's call this point as construction of a DC machine instead of just 'construction of a dc 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.
