                Two ways are used to improve the power factor, as follows
By combining the
      1.capacitor into the parallel of the load
               This is one of the easiest and easiest ways to improve the power factor. The capacitor always takes the leading current. This eliminates leging currents and improves the power factor.
      2.Cicronas motor connection
           
               The power factor can be upgraded by running the cicronas motor in parallel with over-extension on the line which is to be upgraded in the power factor. Now this is very expensive in the motor cost, where it is used only when there is more advantage in comparison with its price Should be done

      3. Using a phase adwanser can also be improved in the power factor

What is the meaning of dc motor? Work theory, construction and working knowledge of motor

                  The machine which is converted into energy from the DC DC in the form of DC energy is called a DC motor, its working principle is as follows when the current carrying conductor is placed in the magnetic field, it feels a mechanical force, whose direction is flaming The right hand side can be shown as per rule

                 The vision of the composition is that there is no difference between the DC generator or the DC motor, ie the use of DC generators can be used as a DC generator, DC motor and DC motor are only slightly different in the outer appearance. Generator frames are open type When the motor's frame is of close type, DC motor like the DC generator also has a shunt wound, a series wound, and a compound wall type.

                      Fleming is the clock vise  direction of rotation of the motor of the left-hand rule, but the conductor's magnetic field have to cut prices in the opposite direction of the basic electric current flowing in the conductor direction of the EMF produced is present vijacalaka force of the electromotive force default Acting against the flow, called BACK EMF, is fused from above that motor work can only be given to The output voltage is higher than the generated voltage,

                   The direction of the rotation of the armature is based on the direction of the field of the Archeture and on the direction of the main field. Even if the orientation of the field of Archeture is changed, the orientation of the Archeture rotation direction changes. But if the orientation of the archete and the main field is changed together The orientation of the armature does not change,

Cycle, frequency, period, technical value, maximum value, average value, phase, impact, out of phase, lagging, leading, form factor, Q factor?

cycle

              The value of alternating zodiac sign and a complete change in direction is referred to as a bicycle.

Frequency

              The number of cycles per second is called frequency. It is seen separately in different countries. India is usually 50 c / s frequency.

Period

             The time taken to complete a cycle is called a period

Technical value

             The value that is received at any time is called the value of the value

Maxim value

              The maximum value of the zodiac sign during the given time period is called a maximum value and the peak value of the other is also

Average value

                 The average value of the typical values ​​found in the semi-cycle is called its average value, which is also called the average value.

Phase

                 An orgular displacement of two or more alternating zodiac is called phase

Enough

               If the maximum or minimum values ​​of two alterative ones occur in the same direction at the same time and at the same time, then the zodiac is called ineffective ones.

Out of Phase

            Now if the maximum or minimum values ​​of two alterative ones are met at different times, then the zodiac is called out of phase.

Leging

             In comparison to the voltage, its current maximum and minimum values ​​are later on at the time of value, the curtain is called the leging currant.

Leading

             In comparison to the voltage, the current and the minimum values ​​are preceded by the minimum value of the biceps, the currents are called the leging currents.

Form factor

              R.m.s. The ratio of the value and the average value to the form factor is the value of 1.1

Q Factor

             Indicator and capacitor are given the supply of resonance frequencies to the pair in the series, if the voltage in the indicator and capacitor increases, the ratio of Xc / R is that the Xc / R ratio is called the Q factor of the circuit.

What is a power factor? Disadvantages of Low Power Factor

Power factor:

                       The power of true power and the power of aprent power is called power factor.
                                          That is, the power factor = true power / simulatory power
                                                   
                                                          Where true power means the reading of the watts meter
                                                           And simulatory power means the volt meter and ammeter's reading

                                                           I.e. pf = w / vi
               
                           That is, the value of the power factor is the cosine of the phase angle between voltage and current.

Impact of Low Power Factor (In Distribution System):

                           Distribution method increases the power factor as the power factor decreases, Increasing the current increases the amount of power consumed in the line and increases the voltage drop.

On the Impact of Low Power Factor (Household Appliances):

                            Due to the low power factor, the efficiency of this type of equipment is reduced and the speed of the motor decreases with it.

Disadvantages of Low Power Factor:

 If there is a power factor, the power flow will increase for that same power power because the voltage is constant, increasing the current of electricity will increase the copper efficiency and reduce the efficiency of the machinery.
The cost of transmitting lines will be higher for less power factor, so the cost of transmitting power will increase.
Due to the low power factor, the terminal voltage is greatly reduced, so a good voltage regulation is needed for the transformer, generator, and transmission line.
Electricity flows from low power factor to transmission line and switch gear, or in other words, the cost of generation and transmission that means generation and transmission increases

The composition of DC motor

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

DC generator and motor

DC generator and motor

                          The machine mechanical power (mechanical power) that is converted into DC electrical power is called a DC generator, when the machine or machine DC is converted into electrical form in the form of mechanical power, it is called a DC motor, There is no difference between creation of DC generators and DC motors, both of which differ only in their work culture
