Hello, I'm 3d printer master. From today on, I'm going to take the course. We're going to be doing it as a pyphity. I've been trying hard to fill it up with data. I can't finish the course, so ... I'm going to take this course. In the case of a theoretical course, I'd like to take it a little lightly. I'm going to do it, so I'm going to do it in ppt. I have attached all the ppt data to the following data Anybody who needs it gets downloaded. I think it would be a good idea to keep this in mind. Actually, I'm a little bit like this. Let's skip over all the boring theories. Just how to create a 3D printer in one go I wanted to go ahead with this. It's not in the position of the person who's doing the course. I had to do all this. So we're forced to be as simple as we can. I'm preparing for the course easily now. But it's still very hard. I'm trying to explain the difficult principle with a grain of salt. I think it's much more difficult. I'd rather do an amount of Anfer's law. This is how it works with the formula. This is much more comfortable. How can I understand the rules of Angkor Wat? It's harder to do this. Where is this really? Top Level instructors in Noryangjin had fun. I can easily tell you why it's a top tier instructor. I think I know now. This is really what I was born to do. I just started studying. It's hard to explain easily because he's such a person. So I'm going to show you this video now, and it's been a week since we took the last class. I still haven't uploaded the video. I've been trying to film it so easily. The video took a while. But I'm going to do it as fast as I can, and I'm going to do it as quickly as I can. Let's just get this straight. Why does a motor come out when I'm working on a 3D printer? That's because the 3D printer is moving with the motor. In fact, when it comes to motors, You don't have to study so hard. It's just that the motor works this way. Just knowing how much you can handle a motor. It doesn't bother me. So don't think too hard and just listen to it lightly. When you're a motor, what do you usually think? A lot of people imagine a motor that is simply spinning. But this is an electric motor. In fact, the range of the motor is very wide. We typically have a motor in our bodies. Where would it be? That's right The heart can become a motor in our body. Because if you look at the motor and you look at the definition in a little bit more specifically. A motor consumes energy. Working is called a motor. So, technically, Our heart has a way of keeping food can not be careful. They use energy to circulate blood. If I don't eat, our hearts will stop, right? This is what we call a motor. It's a very wide range of motors. Well, our heart could be a motor, too. The fuel in the rocket could be fuel. But one thing you need to know is, Because a motor uses energy to work. Windmill, I'm a waterwheel. The energy that simply converts energy, like this, is the energy. It is not referred to as a motor. So, what is it about electric motors? What kind of principle would it take? Don't take it too hard. I'll just take it easy. In fact, a motor, if you give it electricity, it just needs to run. You don't have to think about it that hard. The motor is basically Lawrence's strength. And then you move on to the laws of Fleming. You've heard a lot of it. Now, Anfer's law! You simply give electricity to an electrified hand. This wire becomes a magnet. Isn't it easy? And then we're going to be able to connect the wires that run through the wires. If you put it between them, The power will be generated. This power is called the power of Lorenz. I'm just going to think about it very simply, and the magnet is now going to be the next big thing. Because they have a push-and-pull nature. Electric wires make seats. But I'm not going to be able to use the magnetic wire If you put them between magnets, they're like magnets. You'll feel the power to move, right? It's Fleming's law that indicates the direction of power. Isn't it easy? You don't have to think hard, just simple. What if we run the electrical wires? The wire becomes a magnet. I'm going to take this magnetic wire Put it between the magnets, and of course generate power. So I'm going to use the electric motor to move around. If you look at this motor a little bit more carefully, Now we have a brush motor. There's a brushless motor, and the difference between these two is that they're not. What it is is, as you can see by its name, It's the difference between a brush and a brush. What is a burush? When I was explaining Anper's law earlier, I told you, with electricity, you become a magnet. This brush provides electricity to the motor. Then why is there a burush? The simplest way to think about it is, the motor keeps running. But if we connect the wire to this turning point, What will happen? Of course, it's because of the constant fornication. The wire's gon na twist. So, after much consideration, I ended up with a spinning player. I'm going to apply a brush that serves as this wire. In friction with the shaft The way electricity is transmitted is the brush motor. Of course, it keeps on friction, so it causes heat. That's not efficient, is it? So, in order to solve this problem, After a hard study of one's ideas This is the brushlese motor. This brush gives electricity, and then it's gone. How can I give you electricity? There's a little bit of a shift in thinking here. It's not that simple, it's that they don't just run the electricity all at the same time. So we can turn around and give them electricity, like a magnet is spinning. So the magnet on the axis of the revolution ... Keep the wires from getting the signal. It's the same thing that makes it follow, makes it spin. Brassiery motor. It's like cutting carrots that you can't keep up with. It's a horse shape, a little bit of explanation. Was it difficult? And it's just that I'm going to stay up all night. I prepared an animation. The magnet has two different poles. It has a pull. And in the end, if you turn this magnet around, The magnet on the axis of rotation will rotate along it. But if you give them electricity in sequence, Because in sequence, he becomes a magnet. The magnet for the naturally rotating shaft will move along. How hard could that be? Now, let's drill down a little bit. To tell you this, I've been explaining this. The motor is basically what we see now. DC motor AC motor and so on. Mechanically, we don't have to worry about precision machines. Usually used in machine tools Most motors for control are used. The typical example is a servo motor and a step motor. This servo motor is designed to determine how much it rotates on a rotating rotary motor. I'm gon na put a sensor on it. We attach gears to control them precisely. The increase in force is called a servo motor. And the Step Motor Step Motor. The brushless motor principle that I mentioned earlier is very similar. Like this brushless motor, you can see the inside axis of rotation. We divide the magnets and wires into small pieces, and we give them electricity in sequence. It's the same principle, right? But this step motor is more powerful than the brush motor. We did it by segmenting it. One step is to give you electricity. One step at a time. It is called step angle. Let me put it more simply. A step motor is called a step motor. Once we give them electricity A constant angle of movement is known as a step motor. It's easy, isn't it? You can handle a motor just by knowing it. There's a motor. How does it work?
