Motor के Winding मैं कौन सा U1 Wire और कौन सा U2 Wire है आज पता करना सीखे@ElectricalTechnician

Friends, before starting the video, I have a question for you. Look, I have a three-phase motor here. Three windings of this type have been done inside this motor. Now, if we want to find the two ends of that winding, then By measuring continuity or resistance, we find out which are the two ends of the motor's winding, as can be clearly seen here, but here I would like to tell you that the The winding that has been done, that winding means that the six wires of the winding, all the six wires are sticking out, they are not connected here, the six wires are sticking out like this, now out of these six wires you will get u1 u2 v1 v2 w1 w2 I mean the numbering which is like 1223 u1 u2 v1 v2 w1 w2 you have to find out the numbering in this way so will you be able to identify the polarity of the winding of this motor, no you can't at all You will find it, if you can, then pause the video right now and tell your answer in the comment box. I asked this same question to 40 students. Not even one student out of 40 answered it. Plus, I challenged them to go to your company. Find out how we can identify its winding. Next day he replied to me that Sir I could not figure out, you please tell me. So I thought why not I tell you also because you may also be wondering about it. You will not know the answer nor will you know how we identify the wire of the motor's winding. Look, first of all, let me tell you that the motor has a total of three windings in it. In this way, now all the three windings which are there, have two ends each of those three windings, as if I tell you here, if we have to connect the motor, then in this condition, what do we do first, we here We measure continuity. What we do is we find out which are the two wires of one winding. On checking continuity, a beep sound will be heard here and we will know which are the two wires of one winding. We will put R phase here. Let's do the continuity of the winding of the Y face and the winding of the B face, then find out which winding these two wires here belong to, now after finding out so much, the biggest task becomes that here But how will we know whether this wire is our u1 or u2. Similarly, how will we know whether this wire is our u1 v1 or v2. This becomes the biggest task and this thing Today I am going to tell you, to find out this, you will find a galvanometer of this type here, this is our galvanometer, you will have to use this galvanometer, you must have seen it in the practical room of your ITI, diploma, B.Tech, like this Of Galvanometer is kept there, using this you can identify the winding of the motor. Before identification, let me show you the galvanometer here, in this, for reflection of this needle, reflection of both the positive side and negative side is done. The option to do this has been given, which means that zero is at its center. Now, if I connect the battery here with this galvanometer, as it is written here as positive, then the positive terminal is here. I have connected it to the negative one and if I search here then you will see that reflection is taking place here, so by looking at the direction in which the reflection is taking place, we can find out which end of the motor winding it is Which is u1 and which is u2, for example suppose I connect the positive terminal of the battery here to the positive and the negative terminal of the battery to the negative of this galeno meter, then the reflection will be in clockwise direction on this side. You will see that here the reflection has happened in the clockwise direction. Now if I interchange the batteries here in this manner and then touch both of them, the reflection that will happen here will happen in the anticlockwise direction on this side. Our needle is moving which means that the needle is moving according to the magnetic field which is being generated by this battery. Now using this we will identify the winding here. I will tell you practically, but before that I Let me tell you the theory so that you can understand it well. See, if you want to identify the winding winding using this Galeno water, then in this condition, what you have to do is simply assume that you have a battery here. That there is a battery here, the positive terminal of the battery is here and the negative terminal is here, so what will you do, you will bring the positive terminal and connect it with the positive terminal of the winding and the negative terminal Sorry you will connect it with the negative terminal of the winding with this other terminal, pay attention to one thing here, I have connected the positive wire on this wire on this side, I have connected the negative wire on this side, now like this After connecting, I will take a galvanometer here, so we can make the symbol of galvanometer like this, so I took a galvanometer here, I will connect the wire of this galvanometer at this place, at this point, like this I will bring the positive wire of the galvanometer and connect it to this wire. Then I will bring its other wire and connect it here, meaning that the battery will be connected in parallel to the winding and in parallel to this Here we will connect the galvanometer. Now, after making this connection here, if our galvanometer is moving in this direction, that is, in the clockwise direction, then in this condition, understand that the first one here The terminal where you have connected the positive wire is your U1, it will mean one, you can give any name, you can give it y, v, or d, it will not make any difference, you just have to write one here, positive means one. After this, if the direction of this cyline is flowing here, then this will happen automatically. Now suppose that by chance, the needle of our galvanometer here, which is in the A direction, has started rotating in the anticlockwise direction. So what will you do in this condition, this end where you have wired the positive terminal, you will write 2 here, do you understand, you have to write 2 here, why do you have to write 2 because here our galvanometer is rotating in anticlockwise direction If you have to pay here then you will mention it, then what you have to do is connect the battery in parallel to the battery winding and in parallel to this winding you have to connect the galvanometer and see in which direction the reflection is taking place if Reflection happens in clockwise direction, which means it happens on this side, like if this needle goes to this side, then in this condition, where you have connected the positive wire here, you will consider it as one, that is, consider it as u1 or v1. Take w1, assume it to be anything, but here it will be one, after that the second will become two, so you will mark here that this end is our u1 and this end will become our u2, in the same way you can mark the second winding You will do it at the present time, let's do it here now suppose what I did here, see what I did on this side, I connected the positive wire of the battery, so I will again connect the positive wire here and connect it with the positive of the battery And I connected the negative wire here, in this way now a galvanometer will be connected here in parallel to this, so I connected the galvanometer here, so I connected the positive wire of the galvanometer here and connected the negative wire here, in this condition If I am here If the reflection happens in this direction then what will I do, here I have written u1 u2 but here the direction has reversed so here I will write, suppose this is the u winding, this is the v winding, this is the db winding, so its Here the first end will be this one because the reflection is happening in reverse direction so w1 will come here and w2 will come here like this now friends before checking the winding of this motor practically I would like to give you a small information friends I have I have a book for all of you whose name is Electrician A to Z Wiring Book.

If you like to read in English language then order the book in English. Now let us continue the video, so whenever you go to connect a motor, the first thing you will do is check the continuity with the help of a multimeter, so with this multimeter I have put it on continuity here and after putting it on continuity, I will touch it once and listen to the beep sound. If the beep sound is coming, it means everything is correct. Now here I have to check the first winding of this winding. which is the other end so like you You will see that when I touched here, no beep sound came, when I touched here, the second sound came, which means that the first winding in this motor, one end of that winding is placed here and the other end is placed here, now if I touch this place I should touch this, I have placed the second prop, first prop here, then I touch here, there is no sound of boopee, it did not come here either, it came here, which means that the wire which is connected to this terminal is connected to the winding of the motor The second end is here, we still don't know which one is u2 and which one is v1. Now let's just check the continuity here. In this way you can check the continuity of all the three windings and separate them. Suppose that these are the two wires of this winding, these are the two wires of this winding and these are the two wires of this winding, after identifying this you will know that each wire of this winding is this, each wire of this winding is Wire this and this winding One by one wire is done, now here you have to do the polarities. For doing the polarities you will take the galvanometer here and first of all connect the wire of this galvanometer with one winding like my first winding here, one terminal of this winding But here I will connect the other wire here, what do I do for this, I have connected it here, now I have to take the other wire as well and take it to the other end here I have to connect this wire with this end, so I connected it at this place as well. Now after doing all this work, I will take a small battery here whose voltage is only 1.5 volts. Now here you will take two wires. One end of each of these two wires has to be connected to the positive and negative side of the battery, like I took both of them here and connected them here. Now after this, I put the probe here at this place. am here it got connected here means it has got connected at this place okay this At the same place where its positive terminal was connected, I connected it to the positive one and the negative one has to be connected to the negative, so we can touch it here, if I touch it then you will see where its reflection will be You look carefully here where the reflection is taking place, you can see that its reflection is taking place in the clockwise direction, okay, so here if the reflection is taking place in the clockwise direction, then as I told you, on the terminal which is your positive one The wire with the terminal pit will be connected, its positive wire is connected here, so we will write it as u1, for example, let's assume that our positive wire is connected here, then it will become u1, okay, one number has to be given to the positive one and the second one which What will be left will become two. So I have named this winding u. So this end of it becomes one and this one becomes two. In this way we have found out the first winding. Now suppose if I do a here let me interchange this let's say what I do is here a This winding would be here, if this one was here then in this condition the reflection would be inverted as if I show here, let me just change it, okay I will change it here so the thing is that you have made a wrong change here I have connected the wires in this way, when you connect them you will see that the reflection is taking place in the reverse direction here, so if the reflection happens in the reverse direction, then you should understand that your numbering here will be reversed, which means that whatever you connect here This will become your two and whatever you connect it here will become your one. Now what will I do here again, I will connect this one to this. Okay, where did it get connected at this place, so now I will connect this one to this. I will take it out, now I will check the second winding and after taking it out, its other end is here, so I will plug it in this place, like this, and after plugging it in, I will take this wire and here this is the wire connect There is another wire I need to connect here, its deflection should be in the same direction If its direction changes, if you did not change the wire, meaning that the red wire was connected here and this negative wire was connected here, in the same way you have to connect it here and here and If in this condition the reflection is in clockwise direction then the numbering has to be done in the same way as you did, that is the first end will become your v1 and the second end will become your v2, this is our v winding If the reflection here gets reversed and its direction changes then what would we do in this condition, we would write two here and one here, well if you want then you can also write no two directly here, you can write one on this side, if your reflection It's happening on this side, okay, you just have to see that the reflection should be in the same direction when connected in the same way, okay, so if you believe that when the flow happens in this side direction and the needle goes on this side, you write it as two. So everywhere 2 2 It has to be written. If you write 2 on this side, then it also has to be written as 2 2. Okay, meaning that you only have to see that the reflection should be in one direction. You have to number each wire in which the reflection appears in one direction. I wrote one here in the beginning, then I will write one in all of them, if the direction is this way, then if it reverses, then I will put two here, okay, so this has also been checked, now after this, the last one is left here, so Finally let's connect it here and it will get continuity here, so I connected it at this place, then I will touch its other end here, the direction is same here, so in this condition its name will be W and its name will be this This will become w1 and this will become w2. So in this way we can do identification here. I hope that through today's video you have come to know that how do we check the pole of the motor's winding.
