00:00As-salamu alaykum. Today we are going to talk about fan motor wires. These are the AC wires.
00:08These three wires are on the side. These are for communication. These are called feedback wires.
00:17There are three of them. And I will tell you today how these three wires work.
00:24I will tell you how these three wires work.
00:28Look at this. Pass it to me.
00:32Look at this carefully. There is a long line here.
00:38Look at this long line. Show it to them.
00:42There is a long line here.
00:44These are positive. They give 5 volts.
00:47Like VCC is positive. It goes from here.
00:51It goes from here.
00:52And where this cross is, there is a negative voltage.
00:56We have to give.
00:58And from one negative, and this third wire, there is no mark on it.
01:03See, on this third, it comes out.
01:07I will show you on this also.
01:10This negative will come here.
01:13This will be positive.
01:15And see this, show it carefully.
01:18See, there is a mark on it.
01:21It is written on it. It is very finely written.
01:24It is a mark.
01:25Let's see in the camera what is written on it.
01:28But it is not necessary.
01:30You have to follow these two marks.
01:32See this.
01:33These are long marks.
01:35This is for positive.
01:36And this is for negative.
01:37This is written on it.
01:38See this.
01:39See the frequency on it.
01:41You can see it clearly.
