The video explains how electric motors are made, from the design of the bobbin winding to the creation of the rotating magnetic field. The process of trifunctional bobbin winding is shown, where an electric current turns the rotors. The rotating magnetic field is responsible for the rotation of the motor. The video explains how the magnetic field works even when the motors are not spinning, and how the design of the bobbin winding is not as obvious as it appears.

• 00:00:00 In this video, you see how electric motors are made, from start to finish. You see the process of trifunctional bobbin winding, where an electric current turns the rotors. The rotating magnetic field is responsible for the rotation of the motor. Maybe you're curious about how the magnetic field works even when the motors are not spinning, so we'll reveal its workings in detail, and join you along the way. The design of the bobbin winding is not as obvious as it appears, and took years of effort to achieve. With iteration of design, analysis, and engineering fundamentals, engineers were able to develop this design. We then begin the journey of design, by understanding the qualities of a good magnetic field. An RF (Radio Frequency) must have a light weight, be smooth, and not distort during its rotation. We begin by designing a RF using a simple coil. When an alternating current passes through a coil, the magnetic flux fluctuates in this fashion. We add two more coils, which produce their own fluctuating magnetic fields. When we sum these fields, we get the combined magnetic field. This design is a failure, because the field is not rotating, and here is where Nikola Tesla comes in. He observed this disappointing behavior of the
• 00:05:00 The video explains how three spinning coils of wire around a circle create a rotating magnetic field. This generates an electromagnetic field with two poles, as shown here. The more coils there are, the more symmetrical and uniform the field will be. It is easy to see that by altering the number of coils, we can generate a rotating field with four poles. However, if we have a problem with the alignment of the coils, we can fix it by removing the overlap between the coils. This will create an electromagnetic field with four poles, which is more uniform and powerful. Finally, the video explains how we can create a rotating field with more poles by adding more coils. This is done by winding the coils around a mold and then pressurizing it to form a compact bundle of coils. The bundle is then put into a rotating machine, and the connections between the coils are tested and adjusted. Finally, the coils are sent off to be used in various industrial applications.
