These videos are AWESOME ! And, you are an excellent communicator. Please don't stop making these videos. The keys points are summarily transmitted simultaneously verbally and visually making for a powerful combination. You are educating the next generation of electrical engineers ! 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 !
Wow, I watched all your videos and I learned so much. I love how you explain so much information so well in such a short video! Would love to see both videos about the windings and more! Hope you don't stop making videos as I want to learn more, you deserve way more love!
Thank you for your nice feedback. It always costs a lot of time to make such a video. I just want to give people the knowledge that really helps them. Your comment definitely helps me to reach more people. Thank you again
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.
Thank you, but unfortunately most of them have more subscribers than I have. I saw that you have a playlist about system engineering. Do you work in that field?
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?
The video on BLDC is important and I have it scheduled, I think the month after next. I give everything, but you know how it is, too many tasks and always too little time. Thanks for your feedback and I wish you a nice weekend.
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?
Thank you very much for your positive feedback. You have seen that I have only a few subscribers and therefore need every support. Wish you efficient day
if i wont to rewind a generator to produce 240V how meny time's must i wind the coiled & which is the best practice i know to wind a coil at 60 terns will give me 120 volts if i ues a Varick to inches the field windings , on the rotter, so di i wind a aster by to 120 windings to Give me me a power out put of 240'v output What did the KVA of that put out . ?
Could you please do a video about fractional and integral slot windings and whats the difference with the distributed and concetrated windings. Thank you very much. 😊
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.
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
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 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).
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?
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!
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.
Wish you a happy new year. Have the topic already on my To Do list for 2022. But may I ask how you come to the conclusion that axial flow motors are very efficient?
@@Electric-Motor I have electric motor from Toyota Prius gearbox, which have 8 pols but i want to know how many Hz have and if is something different in windings?
Because the area under a trapezoidal back EMF is larger than under a sinusoidal one. But this is a general statement and there are of course exceptions.
Sorry, we do this to help keep the viewer's attention, so that the viewer understands the whole context, as this is more complex with electric motors. And maintaining excitement is not so easy with the topic of electric motors.
Over all the video is nice, but I would suggest to consider stop moving your hands that much. They offer nothing extra to the explanation and it is rather annoying as it takes the eyes off the animation
Wow. I loved the animations, the waveforms, the technical terms, and your passion for explaining this. Many thanks for sharing this for free!
Thank you for your nice feedback 😃

Thank u.
What is the winding difference between a motor that works with 50Hz vs 200Hz?
Do you mean for standard induction motors?
@@Electric-Motor I have electric motor from Toyota Prius gearbox, which have 8 pols but i want to know how many Hz have and if is something different in windings?
Because I want to use it as an electric generator!
Jai Shree Krishna 🙏
Thanks for your nice feedback :-)
"A motor with a concentrated winding can generate more torque due to the trapezoidal back EMF."

Because the area under a trapezoidal back EMF is larger than under a sinusoidal one. But this is a general statement and there are of course exceptions.
