1.Yoke:
The outer frame of a dc machine is called as yoke. It is made up of cast iron or steel.
It not only provides mechanical strength to the whole assembly but also carries the magnetic flux produced by the field winding.
2. Poles and pole shoes:
Poles are joined to the yoke with the help of bolts or welding. They carry field winding and pole shoes are fastened to them.
Pole shoes serve two purposes;
i) they support field coils and
ii) spread out the flux in air gap uniformly.
3. Field winding:
They are usually made of copper. Field coils are former wound and placed on each pole and are connected in series. They are wound in such a way that, when energized, they form alternate North and South poles.
4.Armature core:
Armature core is the rotor of the machine. It is cylindrical in shape with slots to carry armature winding. The armature is built up of thin laminated circular steel disks for reducing eddy current losses. It may be provided with air ducts for the axial air flow for cooling purposes. Armature is keyed to the shaft.
5.Armature winding:
It is usually a former wound copper coil which rests in armature slots. The armature conductors are insulated from each other and also from the armature core. Armature winding can be wound by one of the two methods;
lap winding or wave winding. Double layer lap or wave windings are generally used. A double layer winding means that each armature slot will carry two different coils.
6.Commutator and brushes:
Physical connection to the armature winding is made through a commutator-brush arrangement. The function of a commutator, in a dc generator, is to collect the current generated in armature conductors. Whereas, in case of a dc motor, commutator helps in providing current to the armature conductors. A commutator consists of a set of copper segments which are insulated from each other. The number of segments is equal to the number of armature coils.
Each segment is connected to an armature coil and the commutator is keyed to the shaft. Brushes are usually made from carbon or graphite
They rest on commutator segments and slide on the segments when the commutator rotates keeping the physical contact to collect or supply the current.
This video was very helpfull to understanding of dc generater in practical thanks a lot sir ..
pls do a video only on windings of a dc machine
Very useful videos sir. Thank you very much
thanks for this type of videos
Super bro. Please do a video on types of windings in the armature.
GOOD JOB 👌👌
very useful sir.thank you...
the background music is hillarious
+Sabbir Mahmud
Sorry next time
I will do my Best
Thank You for watching
🤣🤣
thanks for this videos
+Raji E
Thanks for Watching
Share this videos
It helps a lot to me bro keep it up bro.Add more videos on electrical subject.Thank u:)
+Vadi Raja
Thank for Watching
Share ur friends
THANK YOU Sir
loved it :)
Very helpful Video
Share ur friends
Tq bro
video is good but if there has explaination of parts it's going to be excellent
See my
Construction of DC Generator teaching videos
Tq
Super sir 👍
Very nice
Very helpful .. but music is really irritating..
Thanks
really too good💪
+Vinoth T
See
Construction of DC Generator teaching video..
U got more ideas
Thank you
+Lowe Frank
Share ur EEE related Friends
Tq
thanks bro
excellent :-)
+Ovi The Hypocrite
Thank You
Are you sure that is a DC motor?, because it sounds like a universal motor.
Commutation converts ac current to dc current not voltage
+santhosh kumar yadav
Thanks for watching
It covert voltage polarity as well
Good
Sir ek permission laina hy appsa main apke video sa screenshot lay lo awer use krlo please
super sir
thank you very much .....
video is too much shaking... also slides changes so quickly that u cant read it properly... n if there would hv been proper explanation it would be better
+Aviya Archana
Thank you for Watching
I will do Best
LEEEZZZZ GOOOOOO 🔥 🔥
great news bro
+shaju rs
Thank You
Share ur friends
Thalaivaa......neenga endha clg la work panreengoa....plz tell me
What are the difference between generator and alternator..
nyc
Es sa main screenshot laina chahta ho aur apps main karonga ye pictures
👍👍👍👍👍👍
the video is cool but the song though, whats the name ?????
sir where is conpensating winding located ?
the stator shown is of a induction machine...NOT dc
thank you
+JIM HARLEY
Thank You for Watching..
Share your Friends about EEE VIDS
Please show slow
BGM is the only drawback😬😬😬😬😬 irritating
+Prakash Aryan
So sorry
Next time I will do best
Thank you for watching
2 fast movement of slides, no time to read
In King Lord Master Friend and my Father Jesus’ Name, Amen.
this is not a DC machine
single phase induction Motor
Yes
Just for example
Tq
Wrong explanation, it is not a dc machine, u dont have clarity on machines
at the start thats not the stator of DC machine but of induction machine...get your concepts right before making a video
this is not a DC machine
single phase induction Motor
Some AC parts
Some DC pars
