There are two types of windings for electric motors. In this video I will show you the advantages and the disadvantages of the two types of windings. Windings for electric motors can be divided into concentrated windings and distributed windings. In a distributed winding, the winding is always wound over at least two stator teeth. In a concentrated winding, on the other hand, only one stator tooth is wound. Electric motors with a concentrated winding are shorter and easier to manufacture. A motor with a concentrated winding can generate more torque due to the trapezoidal back EMF. However, the losses in the copper and sheet metal are bigger. With a distributed winding, you can achieve a higher efficiency, which is very important for electric vehicles. Other distinguishing features, which are important for the design of the winding, are fractional and integer slot windings as well as single layer and double layer.

My personal wish would be to see a video for each section of a classical book on AC and DC electrical motors and drives. In particular, how torque is evaluated analytically and experimentally. Thanks again, and as the number of videos boosts, so will the subscribers. Have an excellent performance and wish you the highest efficiency !

thank you sir i love it and also we would be very grateful if you could explain hybrid axial and radial flux motor that is used in keoingsegg car

@Electric-Motor 2 жыл бұрын

Very complex question. So Koenigsegg uses an axial flux motor because the installation space length is very short. This is a main advantage of axial flux motors compared to normal radial flux motors. But the biggest disadvantage of axial flux motors is the complex lamination of the stator to reduce the losses in the laminations. That is why compound material is often used, which is not electrical sheet but pressed powder. Sounds good, but the losses are greater for medium to high speeds. Therefore it is not often used. However, for very high speeds, the losses in the electrical sheet are greater. It is not the mechanical speed that is important, but the electrical speed. Since the Koenigsegg motors have many poles, the electrical speed will also be correspondingly large. So the use of compound material makes sense. Funnily enough, the market leader for this compound material comes from the same country as Koenigsegg ;-) This is probably not a coincidence. Hope I could answer your question Grayson?

Thank you for creating this videos, their very useful to me :) I am more interested in difference between single layer and double layer

@Electric-Motor 2 жыл бұрын

In short, the difference between a single layer and a double layer winding is very small. With a single layer winding, there is only one winding in a stator slot, with a double layer winding there are two windings. The problem with a double layer winding is that the two windings in a stator slot can be of two different phases. Depending on the winding configuration, this can lead to unfavourable current displacement. Thanks again for your question, I will explain the details in one of the following videos.

Could you make video for design of distributed windings, how much in numbers and how many turns needed and from where we should take our phase in and phase out wires. And how the motor is connected to drive and controller.

@Electric-Motor 2 жыл бұрын

The design of the winding is quite complex. I do not even know a book that describes the design of the winding well. As a small tip, when you compare winding configuration, always look at only one phase. That simplifies the analysis of the function and unetrschiede enormously. Thanks again for your nice feeback

Thank you for share these very useful information. Why magnetless switched relutance motors are not used for automotive traction ?

@Electric-Motor 2 жыл бұрын

Switched reluctance motors have a smaller power density than an electric motor with permanent magnets and the efficiency is lower. However, car manufacturers also use the reluctance torque to reduce the expensive magnet material. The motors are called IPMSM and are a combination of a PMSM and a synchronous reluctance motor. Thanks again for your question, I hope I was able to answer it in a few words?

Concentrated windings does not automatically mean worse Back-EMF! It is a common misunderstanding that the increased losses are caused by higher harmonics in the BEMF. What is generally true, though, is higher losses due to more spatial harmonics in the airgap!

@Electric-Motor 2 жыл бұрын

I am very happy that people like you, who know a lot about electric motors, watch my videos. However, exactly in the video I said the following: "And also with concentrated windings a sine wave back EMF can be achieved by adjusting the rotor design". But I understand that when people are already well familiar with the subject matter, they don't listen that closely anymore. I also try to keep the complex context as simple as possible, so that people who may not have studied and are from poorer countries can easily acquire knowledge about electric motors. So everybody has the possibility to write questions about electric motors under my YT videos and get simple and uncomplicated answers. Nevertheless, many thanks for your comment and your support.

Maybe it would be worth analyzing my work on the new generation of a synchronous motor, the Brushless Hybrid Fast - Rotation Motor, operating on the basis of the winding angle of 135 and 180 degrees. My analysis and tests are very promising! Happy Easter, greetings!

@Electric-Motor Жыл бұрын

Looks very interressant, what is the essential and difference in function?

@ZygmuntKiliszewski Жыл бұрын

@@Electric-Motor Thank you for your answer. A. Base angle 135 degrees. The symmetrical winding, based on a pole angle of 135 degrees, generates a delta function current on two pairs of motor control lines [L1 - L3 and [L2 - L4]. This effect has been confirmed in numerous load tests in the generator function. The engine mode is dominated by the function generated by the controller supervising the operation of the engine. B. Base angle 180 degrees. The asymmetric winding, based on the pole angle of 180 degrees (phase A - B: 90 degrees; phase B - C: 135 degrees; phase C - D: 90 degrees; phase D - A: 45 degrees), generates on two pairs of motor control lines [L1 - L3 and [L2 - L4] isosceles trapezoid function current with vibrations at the peaks. The winding system is slaved to power the synchronous machine, in four steps per revolution, with a sine function current or any dependent on the calculations of the supervising controller. Regards! --- I gave a detailed answer a few hours ago, but I still don't see my comment (16.04.2023 r., 19.08).

@Electric-Motor Жыл бұрын

You can achieve great things with asymetric winding. However, this usually leads to asymmetrical use of the stator laminations. This often leads to high losses in the laminations. Have you ever measured the efficiency? And if so, what efficiencies do you get?
