Types of Rotors - Different types of Rotors and their characteristics - Duration: 5:20.
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator,
or alternator.
Its rotation is due to the interaction between the windings and magnetic fields which produces
a torque around the rotor's axis.
In this video we will go to learn different types of rotor.
If you like this video, so please subscribe our channel learning Engineering.
In induction motors, generators and alternators have an electromagnetic system consisting
of a stator and rotor.
There are two designs for the rotor in an induction motor: squirrel cage and wound.
In generators and alternators, the rotor designs are salient pole or cylindrical.
Here we discourse four types of rotor.
1.
Squirrel-cage rotor.
2.
Wound rotor.
3.
Salient pole rotor.
4.
Cylindrical rotor.
Squirrel cage rotor.
The squirrel-cage rotor consists of laminated steel in the core with evenly spaced bars
of copper or aluminum placed axially around the periphery, permanently shorted at the
ends by the end rings.
This simple and rugged construction makes it the favorite for most applications.
The assembly has a twist: the bars are slanted, or skewed, to reduce magnetic hum and slot
harmonics and to reduce the tendency of locking.
Housed in the stator, the rotor and stator teeth can lock when they are in equal number
and the magnets position themselves equally apart, opposing rotation in both directions.
Characteristics of Squirrel cage rotor.
This rotor rotates at a speed less than the stator rotating magnetic field or synchronous
speed.
Rotor slip provides necessary induction of rotor currents for motor torque, which is
in proportion to slip.
When rotor speed increases, the slip decreases.
Increasing the slip increases induced motor current, which in turn increases rotor current,
resulting in a higher torque for increase load demands.
Wound rotor.
The rotor is a cylindrical core made of steel lamination with slots to hold the wires for
its 3-phase windings which are evenly spaced at 120 electrical degrees apart and connected
in a star configuration.
The rotor winding terminals are brought out and attached to the three slips rings with
brushes, on the shaft of the rotor.
Brushes on the slip rings allow for external three-phase resistors to be connected in series
to the rotor windings for providing speed control.
Characteristics of Wound rotor.
This rotor operates at constant speed and has lower starting current.
External resistance added to rotor circuit, increases starting torque.
Motor running efficiency improves as external resistance is reduced when motor speed up.
Higher torque and speed control.
More information about rotor, so please visit www.learningengnr.com
Salient pole rotor.
The rotor is a large magnet with poles constructed of steel lamination projecting out of the
rotor's core.
The poles are supplied by direct current or magnetized by permanent magnets.
The armature with a three-phase winding is attached to three slip rings with brushes
riding on them and mounted on the shaft.
The field winding is wound on the rotor which produces the magnetic field and the armature
winding is on the stator where voltage is induced.
Direct current from an external exciter or from a diode bridge mounted on the rotor shaft,
produces a magnetic field and energizes the rotating field windings and alternating current
energizes the armature windings simultaneously.
Characteristics of Salient pole rotor.
This rotor operates at a speed below 1500 revolutions per minute and 40% of its rated
torque without excitation.
It has a large diameter and short axial length.
Air gap is non uniform.
Rotor has low mechanical strength.
Cylindrical rotor.
The cylindrical shaped rotor is made of a solid steel shaft with slots running along
the outside length of the cylinder for holding the field windings of the rotor which are
laminated copper bars inserted into the slots and is secured by wedges.
The slots are insulated from the windings and are held at the end of the rotor by slip
rings.
An external direct current source is connected to the concentrically mounted slip rings with
brushes running along the rings.
The brushes make electrical contact with the rotating slip rings.
DC current is also supplied through brushless excitation from a rectifier mounted on the
machine shaft that converts alternating current to direct current.
Characteristics of Cylindrical rotor.
The rotor operates at speed between 1500 to 3000 RPM.
It has strong mechanical strength.
Air gap is uniform.
Its diameter is small and has a large axial length and requires a higher torque than salient
pole rotor.

Samsung Galaxy S8 vs OnePlus 3T Camera Comparison - Duration: 3:54.
"Music"
Hey guys its Sagar from Tecworkz.
In my camera review of the Galaxy S8, I called it the best camera on any smartphone in the
market right now.
In this video, we will try to find out, where does the camera of the OnePlus 3T stand, in
comparison.
I know the OnePlus 5 has already hit the market with its fancy dual camera setup.
We have it in the studio, and I am working on its camera review and comparison with the
S8, as you guys are watching this video.
But until that video comes out, let us see how does the camera of the OnePlus 3T hold
up against that of the S8.
Now before we get started, make sure you hit the subscribe button, so you don't miss out
on any of the amazing videos coming up on this channel.
On the S8, You get a 12 Megapixel rear camera with f/1.7 aperture, Optical Image Stabilisation
and single LED flash.
Whereas, The OnePlus 3T has a 16megapixel rear camera with f/2.0 aperture, Optical image
stabilisation and single LED flash.
At the front, you have a 8 megapixel camera with f/1.7 aperture on the S8, and 16 megapixel
camera with f/2.0 aperture on the OnePlus 3T.
The camera module on the S8 is almost flushed in with the back of the phone, but the one
on the 3T sticks out quite a lot.
Interface of the camera app is pretty simple and intuitive on both these devices.
Both the phones offer to capture RAW images and have manual controls, so you can have
better control over the images that you take.
Now lets get to the images and videos that I took with these smartphones.
All the images have been shot in auto mode with auto HDR turned on.
Right from the first image, you can see that the S8 takes detailed, sharper images with
better contrast.
Overall images from the 3T are also pleasant to look at, but the better processing on the
S8 makes its images stand out.
Colours on from the S8 are more saturated of the two, and depending on your preference,
you might like it or you might not.
S8 has captured more light in this image thanks to its wide aperture, and as we zoom in, you
can see lot more noise in the image from the OnePlus 3T.
Here is a quick test between focusing speed of these devices.
OnePlus does a good job while switching its focus from near to distant objects, but the
S8 is even better.
Focusing is faster and a lot smoother to look at, which is important if you plan on taking
lot of videos with your smartphone.
Now here are some close up shots.
Ones from the S8 are brighter and slightly more detailed, but the ones from the OnePlus
3T are equally good to look at.
3T starts to struggle a bit in lower lighting situations, where it captures more noise than
the S8.
As we start shooting in lower lighting situations, S8 starts to pull way ahead.
3T sometimes even struggle to latch on focus in these situations.
This image from the S8 looks so much better and richer, zooming in, we can even see the
text being much sharper in its images, compared to the one shot on the OnePlus 3T.
The 16 megapixel front facing camera of the 3T takes more detailed images, when compared
to the 8 megapixel camera of the S8.
Now coming to the video performance.
Both can shoot videos in upto 4k resolution at 30fps, and have optical image stabilisation,
but the video from the S8 is much better.
As you can see, the video from the 3T is not very stable.
It's not at all bad, but I expect better results from cameras with Optical image stabilisation
built in.
The 3T has another problem of continuously hunting for focus, which is really annoying
at times.
The camera of the OnePlus 3T seems to lack far behind in this comparison, But it can
certainly take good pictures in ample lighting conditions.
And on its own, the OnePlus 3T has a great camera at its price range.
If you are looking to make a decision between these smartphones, based on their camera performance,
you should definitely go with the Samsung Galaxy S8, if you have the budget for it.
If you don't have that kind money to spend on a smartphone, but still want a great phone
with a good camera, go for the OnePlus 3T, if it is still selling in your country.
OnePlus 5 has already hit the market, with improved dual camera setup, and I hope it
stands a better chance against the S8.
That is it for this video guys.
What are your thoughts on the camera of both these devices, let me know in the comments
section.

At The Tate Modern, Art And Play | The Daily 360 | The New York Times - Duration: 3:21.
It is inspired by the ancient quipu idea of talking knots,
which was how the Incans recorded history.
The visitor would come into the room at first unsure of how to
interact with these ropes.
But as soon as they knew that they could touch these ropes,
that they could feel them, that they could throw them around,
everything changed. It was like their bodies became part of the work.
There was a kind of childish delight in moving through the space.
The first thing you encounter is the smell. It was this earthy, loamy smell.
Lewis had filled the entire foyer with couches and this
explosion of house plants that were almost aggressive in nature.
At times it was unclear who was part of the work and who was a visitor,
who was a dancer and who was just there to see what was going on.
I'm not sure the distinction mattered.
"Anywhen" resisted description. Hashtag, you had to be there.
An amalgamation of video footage, of ventriloquism,
cuttlefish and cityscapes, a manic marquee sign,
a graceful beacon lamp that slid the length of the space,
a motley assortment of inflatable fish and a plethora of tiny speakers.
No two moments were the same, and here was the kicker,
this whole universe was controlled by a jar of yeast,
the sounds of the museum and an algorithm.
Sounds complicated? Good. It was.
"London Fog" felt at once minimal and complex.
There was a sort of profound dialogue between the elements
and the artists, between museum and the city around it.
Around me, the fog was changing with the breeze.
It rose up and twisted, obscuring the world beyond.
For a moment, I was trapped in a cocoon, completely transported.
And then the mist broke, and I was standing next to a
museum inside a great and beautiful city.
There's so many different ways to move through the museum.
You can use it as a thoroughfare, as a picnic spot
as a place to declare your love, as a place to fall asleep.
A museum needs to contain all of these spaces.
In a way a city should be designed like a museum.
Places for collision, places for thinking,
places for commerce, places for art-making.
A city and a museum should not be all that different.

Ronan Meets Thanos | Guardians of the Galaxy (2014) | Movie Clip - Duration: 2:07.
You have been betrayed, Ronan.
We know only that she has been captured.
Gamora may yet recover the Orb.
No.
Our sources within the Kyln say Gamora has her own plans for the Orb.
Your partnership with Thanos is at risk.
Thanos requires your presence.
Now!
With all due respect, Thanos, your daughter made this mess.
And yet you summon me...
I would lower my voice, Accuser.
First, she lost a battle with some primitive.
Thanos put Gamora under your charge.
Then she was apprehended by the Nova Corps...
You are the one here with nothing to show for it.
Your sources say that she meant to betray us the whole time!
Lower your tone!
I may be your...
I only ask that you take this matter seriously.
The only matter I do not take seriously, boy...
Is you.
Your politics bore me!
Your demeanor is that of a pouty child.
And, apparently, you alienated my favorite daughter, Gamora.
I shall honor our agreement, Kree, if you bring me the Orb.
But return to me again empty-handed...
And I will bathe the starways in your blood.
Thanks, dad.
Sounds fair.
This is one fight you won't win.
Let's head to the Kyln.

Top 5 Things to Do in the Destiny 2 Beta - Duration: 2:44.
Early access to the Destiny 2 beta starts today, at least on PlayStation 4, so if you've
got a code or you pre-ordered, you should be ready to play when the gates open up at
10am PT, 1pm ET, and 5pm GMT.
If you haven't got a code, and didn't bother pre-ordering, you'll have to wait
for the open beta, which kicks off on Friday 21st.
So once you have access, what should you do?
Well, the Destiny 2 beta boasts quite a lot of content, and it's important that you
see all of it.
To help guide you, we've put together this video.
I'm Mack, for PlayStation LifeStyle, here with the top 5 things to do in the Destiny
2 beta.
Remember the epic Destiny 2 gameplay reveal that we saw back in May?
Well, you'll be able to experience that opening story mission for yourself in the
beta!
Start in the Tower, the social space that your Guardian has been calling home for years
now, and fight to defend it from the Cabal "Red Legion."
Team up with the Vanguards as they do all they can to survive and protect Earth's
last safe city.
The new three-player cooperative strike, called "The Inverted Spire," is also playable
in the beta.
Grab two friends, or matchmake with other players, and go up against the Cabal and Vex
on Nessus.
Beat the boss to complete the strike and get some of that sweet new loot!
Even if you're primarily a Destiny PvE player, Destiny 2's PvP portion is definitely worth
checking out.
Some big changes have been made, including a reduction from a 6v6 player count, to less
chaotic 4v4 matchups.
There will be two modes to play and two maps to play on in the beta.
The Control game type makes a return, along with a new attack and defend Countdown mode.
As for maps, players will be able to check out Vostok and Endless Vale.
The Farm is a new Destiny 2 social space that you'll be able to visit in the beta.
The reason it's so high on our list today, is because it will only be available for a
short period of time.
On Sunday July 23rd at 10am PT, 1pm ET, and 5pm GMT, The Farm will be accessible for one
hour, and one hour only!
So be online and be ready!
It's going to be one hell of a stress test, so try and keep your patience!
Though you may well have your favorite from the original game, we urge you to invest time
giving all three classes a go during the beta.
With new abilities and subclasses, each class should feel different.
Then there's the new weapon categories: Kinetic, Energy, and Power.
The big addition here is the Power weapons, which are extremely lethal and fantastic fun
to use.
Those are the top 5 things to do in the Destiny 2 beta.
What are you most looking forward to trying out?

14 Curiosidades sobre a Jean Grey - Duration: 3:48.
What's up guys!
Another video for the channel
Today bringing the 14 curiosities about Jean Grey, so get rid of them and go for them!
1. Her had his first appearance on Uncanny X-Men # 1 in September 1963
2. Also called by Phoenix or Marvel Girl
3. It was created by Stan Lee and Jack Kirby
4. At the age of ten, Jean saw her best friend, Annie, get run over.
Jean's emotion as she held her friend as she died caused her powers to awaken,
and because of her telepathy, Jean felt all the pain of her dying friend.
5. Jean Gray is an Omega-level mutant
that would be mutants with the ability (or potential) to transcend the bonds of physical existence,
be able to control matter and energy on a sub-molecular scale,
as well as having a body capable of containing size Power without external aid, are other requirements.
The gift of Immortality is also a possibility, but not a requirement.
6. Has as its main powers Telekinesis, Telepathy, Pyrokinesis, Psionic Burst, Temporal Manipulation, Cosmic Power, Resurrection Power of a Phoenix
7. Jean Gray is known to die several times.
Seldom were those she actually died, in some it was only given as dead, or vanished for a while.
And these were all the times she died.
8. "White Hot Room", is a kind of "afterlife" and base of operations of Phoenix.
his is where Jean Gray and Phoenix remain until needed.
According to death itself, the place is "the Alpha and the omega,
the beginning and the end of everything, where the physical universe joins the realm of spirit and imagination."
9. This was invented, for after the Black Phoenix had destroyed and killed several beings,
the editors felt that they should be punished for it. So Jean, after his sacrifice on the moon,
spends a lot of time creating palaces for the souls that were there because of him.
10. Inside the warm white room is also the crown.
Often Jean spoke of the artifact and, according to Phoenix consciousness,
Jean is the "White Feast of the Crown," but what the Crown means has never been revealed.
11. Madelyne Pryor is a clone of Jean Gray, created by Mr. Sinister,
who believed that a union between the Summers and Gray lineages would result in a powerful mutant capable of defeating the Apocalypse.
12. On television, she appeared in X-Men: Animated Series, X-Men: Evolution, Wolverine and X-Men and Iron Man - Iron Man
13. And in theaters appeared in X-Men: The Movie, X-men 2, X-Men 3: The Final Clash, X-Men: First Class, Immortal Wolverine, X- Men: Apocalypse
So that was the 14 curiosities about Jean Grey
I hope you have enjoyed commenting below what you found and the next topics for the 14 curiosities
Thanks and until next time!
