The composition of DC motor


   Theory


                    DC motors operate on the principle of transformation in the electrical power of electric power,


  Parts of DC Motor


                                        Parts of DC motors are divided into two sections
                                                         1. moving parts  and 2. Fixed part


Moving part


   Armature:


                   It consists of conductors and a computator in the form of laminated core or sounding of magnetic material, slot mounted in the armature core, in which the conductor is placed in the form of coils.
                   The function of the armature is to rotate in the Uniform Magnetic Field

 Commutator:


                  Commutator copper is of ring type but it is a combination of small pieces. One piece is called a segment. Each segment is insulated from one to another and tightly combines many segments, it is fitted on the armature insulated shaft and it is computator It is said that terminals of winding are sealed on the segment, arm Carbon brushes are kept on this computer for selection on the above surface. Here, it is understandable that the computer is a rotating part while the brush is stable

  Shaft:


                  The shaft is in the shape of a rounded steel steel, in which both the ends are inserted into the bearing of the body of the motor. The commuter, armature, and cooling fan above the shaft is kept on the shaft, with the help of the shaft, Moves in

  Cooling Fan:


                 The clinging fan is shaped in a pvc or a foil made of a steel. It is fitted on the shaft, when the armature rotates, it also rotates its motor into the motor to push the heat out of the motor so that the motor remains cool inside And help the motor not to be hot

  Bearing:


                Bearing is made of cast iron, and it is also included in the moving part. It is fitted into the body of the motor. And the shaft is trapped in it, with the help of bearing, the shaft can move independently.
               So these were moving parts, we will now learn about the frozen parts




Fixed parts:


  Body:


                   The body of the body of the body is made of steel, the body of the body is lodged in the body. The two parts of the body of a mover are to unite all parts of a motor and to carry two magnetic fields.

 Hook:


                 A hook is found in the upper part of the body of the motor body, it is also called the iron bolt. With its help, the motor can be switched from one place to the other and replaced by a space on the other.

mainpol :


              Mainpole is inside the body. It is vibrated on top. This poly can also be found in two or four, it is made by adding a thin band of silicon steel.

Field Coil:


              The vines which are above the mainpoll are called field coils. This string is of the super-anomal type of copper wire.

Carbon Brush and Brush Gear:


            Carbon Brushes are used to supply supplies to the commuter in the motor. The supply is found in the armature. And the brush has the function of brush gear.

Covers:


              Covers are attached to the body of the motor, in which the bearing is attached, which is attached to the body both sides.

Terminal Box:


              A box appears on the body or above the body in which the terminals are found. The end of field winding is attached here, which can be supplied from the outside.

Name plate:


              A plate is found on the body of the motor, in which all the details of the motor are recorded

ERTHING

ERTHING                        Electricity is beneficial for us, but its loss is even more. Electricity can take our lives even if it does not go well. Now we can not get away from electricity because electricity has become part of our life. Light in the darkness, fan in the heat, so much of the electricity around us that we They even use it inadvertently. Along with this, the risk goes up. For this reason, we must definitely adopt a path of goodwill which can secure us and our own electricity so we must definitely do our work in our home to avoid all these. But first, do you know what the meaning is?  What is Erthing?            We have so many electric appliances in our house around us that sometimes we have been using it. Therefore the electrical equipment is in contact with our body, and therefore whenever there is a fault in the instrument then the body of the instrument comes in contact with us, so that the current passes through our body and we feel shock O

D.C 3 POINT STARTER

                                 It can also be called a three point starter. Its structure is shown in Figure. To start the motor, the handle is moved from off position to the first contact position. The total obstacle is in the armature circuit, the field connection is connected directly to the supply through a volt coil. Comes in as soon as the speed of the motor increases in the same way as the archete back emf emits and decreases in the value of current Now the handle is moved to the second step. Again this type of function will be done eventually at the last step of the handle. This time the armature will connect directly to the supply and this time the handle does not come with a no-volt coil. The magnet will hold the handle in the walt coil, and the motor will not need to hold the handle to continue and the motor will rotate in full speed.                   Mechanism of 3 points Starter is done so that if the magnetism of the nvc coil is exhausted for any reason, and the

DC Compound Generator

DC Compound Generator:                     This type of generator is a mixed example of series and shutter generator. In this generator, its internal field has the connection of series and shunt type. Its connection is found in the figure. This type of generator has two main types. 1.Comyutetiv Compound Generator 2. Diffractional Compound Generator Commutative compound generator also has two types again 1.Comyutetiv Short Shunt Compound Generator 2.Comyutetiv Long Shunt Compound Generator Similarly, there are also two types of differential compound generator 1. Differential Short Shunt Compound Generator 2. Differential Long Shuttle Compound Generator              Since the use of Short Shut Commutative Compound Generator is overly used, we discuss that the combination of the shunt field in the generator of this type is done in the acrostic armature. And the direction of current from the shunt field and direction of flowing from the series field is the same.
