DC AND AC GENERATORS:
Electric generators are devices that transform mechanical energy
into electrical energy. Further transmission and distribution of the generated
electrical energy for household and commercial purposes occurs through
power lines. There are two types of generator, the DC and the AC
generators. Us, students can learn more about this subject and retain the
information more easily if we are aware of how AC and DC generators
works and the difference between them.
An device known as a DC generator transform mechanical energy
into DC ( direct current ) electricity. Electromotive force that has been
energetically induced is the basis for the energy transformation process. DC
generators supply electricity to very large electric motors, such as those
required for subway system. While an AC generator is a type of electric
generator that transforms mechanical energy into alternate emf, or
alternating current, electrical energy. The “ electromagnetic induction ”
theory underlies how an AC generator operates. AC generator is utilized to
run a electrical appliances and smaller motors at home like mixers, vacuum
cleaner, etc. Furthermore, based on the fundamentals of electromagnetic
induction and Faraday’s law, both of these generators generate electric
energy. According to this law, as a conductor travels inside a amgentic
field, it breaks magnetc line of force, which causes an electromagnetic
force to be induced within the conductor. The flucx change rate
( magnetic line force ) coupling with the conductor determines the intensity
of this produced EMF. If the conductor is close, the EMF will cause a current
flow.
To conclude, generators have a big impact in our modern society ,
especially on how they wokrs. Hence, the two most fundamental and
important components are the magnetic field and conductors which
move inside that magnetic field.
DC AND AC MOTORS:
Electric motors are devices that use rotational force to transform
electrical energy into mechanical energy, which can come from either a
direct electrical connection or storeed energy. There are two types of
motors, AC and DC motors. If we are aware of how AC and DC motors
works and what makes them different, we, as a student, cann study more
about this subject and retaiin information more readily.
Alternating current powers AC motors whereas direct current powers
DC motors. An electrical device that transforms electrical energy into
mechanical energy is a DC motor. A current-carrying conductor
experiences a mechanical force whenever it is placed in the magnetic
field. This is the fundamental operating principle of a DC motor. While an
electric motor that uses alternataig current t provide mechanical power
known as an AC motor. The electromagnetic induction theory underslies
the operation of an AC motor. They are divided into two categories,
synchronus and induction motos, based on how they operate. Since AC
motors can produce more torque by employing a tronger current than DC
motors, they are often regarded as being more powerful. DC motors, on
the other, often use their input energy more effctively and are more efficiet.
In order to meet the power requirements of any business. Both AC and DC
motors are available in a variety of size and strength.
To conclude, almost every industry relies heavilly on electric motors.
Our faacility will work more smoothly if we use the proper kind of motor ,
high-quality parts, and routine maintinance. This will aslo stop wear and
power surges from harming the endpoint equipment.
