Induction Motor
Induction Motor
The
Induction motor was invented by Nikola Tesla who was a great inventor in the
centuries XIX and XX. The induction motor is also known as asynchronous motor
these are A.C. motors, these types of motors generate electrical energy or can work with currents oscillating A.C. depending of the objective of its use while the
D.C. motors consist on generators that
establish currents continuous,
meaning that the currents has the same direction every time but can change its magnitude or has
continuous magnitude for some time, all these things depends of the source and these type of motors can also employed in generation of currents D.C. or many other applications with currents D.C. REMARK. A D.C. motor is different to a A.C motor. When
we say alternating currents A.C, this means the change of direction of the
currents i.e. these currents has a direction in some instant of time and another
direction in other instant of time. This behavior is illustrated in the next
graphic.
These AC motors are used in industrial drives because they are rugged, reliable and
economical.
The
induction generator or asynchronous generator is a particular induction motor to produce power from mechanic energy transformed on electrical energy,
these are used in the generation of electrical energy. Thanks of these types of
motors Nikola Tesla thought on generating alternating currents and used these
currents in the electric energy transmit. All these things happened in 1893 in
a public exhibition in Chicago, with this exhibition Nikola Tesla demonstrated the
higher power of the alternating currents because before the cost of energy
transmit were very expensive because
were used continuous currents D.C. and the wires were very widths. With
the alternating currents Tesla only needed thin wires and the efficiency on
transmit energy electrical was higher and cheaper than the cost by transmit electrical
energy with continuous currents D.C. Today this system of transmit power A.C. it is used in all the world for the reasons that are explained in this text. Additionally the induction motor today is used
in many works as in the kitchens with the use of the blenders and mixers and
many others appliances and tools in the industry.
The people in the scientist world say that Tesla invented in all your life more of 300 patents and many of these were discover after the dead of Tesla. Today many of these patents everybody knows its existence.
motor these are AC motors--punctuation
ReplyDeletethese types of motors generate(s) electrical energy
this meaning changes in the directions (this means the change of direction)
these currents has---has? a direction
that are explained
the use(d) of the blenders
world scientist --word order
I made all the corrections in this text. Thanks very much teacher.
