I'm heading into school soon for 3rd year electrical... I have been using all your lessons for over 3 years now. You have taught me so much. I wish I could chat with you one day. Thank you for all your lessons over these past few years! You have been instrumental in developing my understanding of electricity and I believe I am a better electrician as a result. Really can't say thank you enough. With deep admiration and respect, sir, Thank you!!!
This would explain 3-phase motors in most ebikes today. I’m teaching myself how to repair my ebike. Frustrating but enjoyable process. Funny story😏controller died on my ebike when I got caught in rain. 2nd controller in six months. Fed up😡with mediocre customer service in getting parts (please…never said I’d do it myself. Cut the motor cord to keep me motivated, bought parts, watched tons of TH-cam videos and finally. After about a week of going from knowing nothing to learning the basics, I upgraded my controller (checking MOSFETS, resistance, etc are correct), added new LCD display, and learned all about Hall sensors, 3-motors, amps hour, voltage, power, phases, etc in the process. AND that hub motor spinning the other day 💪🏾 Videos like your help a lot. Thanks. /Bklyn👑
I know im asking the wrong place but does anybody know of a trick to log back into an instagram account?? I was dumb forgot the password. I appreciate any help you can offer me.
@Axel Ali i really appreciate your reply. I got to the site through google and I'm waiting for the hacking stuff now. I see it takes a while so I will get back to you later when my account password hopefully is recovered.
I'm Electronic Engineer working as software programmer, in these days my interest caught by solar and started solar training and your video help me lot to understand clearly 3 phase 😀
I worked in a textile mill years ago and most everything in the mill was 3 phase. You don't need a start or run capacitor on a 3 phase motor. You have a problem you just ohm it out and look for a short or a bad bearing or bushing. I can tell you a little old school secret I learned. If a motor is hot when you check it then it is good. A motor with an open winding will cool off since it isn't trying to run.
@@vxnova1 yes but in 3 phase there is no need for the cap cos atleast 2 of the phases always have torque even if 1 phase has 0 torque therefore start up cap is unnecessary
You are a very good teacher. You can explain in a very simple manner trying to let the listeners understand even if they don't have enough background in electricity/ electrical circuits. Do more videos on basic electricity. Thanks.
I wish you were my instructor when I was in school. Your discussions are clear and well defined. I've learned more from you than I did in school. I've better understood learning on my own but better examples in these videos.
I took Robotics in College, I struggled so much with electricity and electronics. I was able to follow you in your short lesson more than what hours of beating my brains could accomplish.
This video brings back memories of my electrical class in 1978! I hated my electrical class, made no sense. This is great information if you want to teach this math. Simply put, an alternator has equally spaced coils connected into three outputs each is 120 degrees apart. No big deal! I started as an electrical drafter in 1983, fell in love with my job and stayed with it until 2018. I designed residential, commercial, and industrial projects almost all with three phase systems. I became a PE in 2007. The point is, this point should be a 2 minute discussion and done. In the whole time of designing systems, I never used the math shown here. It's useless in the real world. But if you want to teach, it's good to use up time.
Hello, thank you for the informative video. It answered some of the questions I have as I learn about electricity. However, I think there might be a problem with some of the math... if you have a cos b(x-c) + d, you get a magnitude of a, a dilation of b, a horizontal shift of c, and a vertical shift of d. Now the one I think might be incorrect in the video is the horizontal shift of c. If you have +120 degrees, then that should shift left (or negative), not positive. The reason is that c is subtracted, so if you make it +, then you are subtracting a negative. Likewise, if you are going to do -120 degrees, that should be a shift to the right because you are subtracting the positive value of 120 degrees. So if you have cos (x - 120) that means the cosine graph shifts right 120 degrees. If I am misunderstanding something, please let me know because I want to understand this, but I think that might be wrong, so I'm asking for your input. Thanks!
Thank you. You are the best instructor I have on this subject. I probably have this thing more than 30 times since high school, but this is the first time I really find it useful and make sense. It is your "MOTIVE" method makes the new knowledge associate to things I already know, smoothness operation of motor. I guess none of my previous instructors really works in this motor design job. One suggestion, start with a resistor to explain the power thing 3 phase world probably cause confusion. Negative power for capacitors and inductors? Do you mean some thing get colder when pass current to it? If I am teaching this, I will use a running motor as a model only, There is no isolated resistor, capacitor, or inductor. And the power is not just heat, but heat plus rotational energy. Negative power means put breaks on and take out rotational energy. Power hear is Power Flow, with direction, source, and destination. Some of my words may need refine, but I have a clear a model now. on your first video, I watched in 3 sections, about 5 min. each. Rewind a little, paused a few times, until the image of fast turning motor becomes solid at the center of my view. This image probably not good enough for you, but is good enough for me not to push the 3 phase world aside. If a running motor, may be an old record player, is running in the background, with unsteady speed, it might help student. Thanks again.
In the 1980's as a Cadet Deck(Navigating Officer) on ExxonMobil Tankers(then Esso) we had to learn about the 3-Phase System with electrics on Sluice and Penstock Valves in Cargo Tanks. Anybody without "A" Level Physics struggled with this ! Luckily we had a very senior Electronics Officer onboard (not a Sparkie) who explained it all to us and his name was Tom Morley a huge Guy with a beard.(Epaulettes 3 gold stripes with green in between ...a very rare rank)
I told myself I'd learn more about AC power but my head hurts because I just spent two hours learning about machining, 4 hours learning about the current state of world politics, and how the silent civil war here in the U.S. is going and that's enough for my day off. I don't know anything about these phasors you're speaking of, it just makes me think of Star Trek but I do understand the concept of 360 degrees in a wave vs a circle because I've studied sound engineering a bit. I think I'm going to go play some Far Cry 4. If anyone wants to give me some pointers on where to start in learning AC power, I would much appreciate it. I understand just the real basics of what AC is, vs DC and 120/240, 3 wire single phase, midpoint neutral but if I need to start at the very beginning then I will.
Wonderful and gifted tutor! Your skills of communicating your knowledge is superb Sir! Maths was never my strong subject. I wish I had you as a tutor when I was at college. Keep up the great work with your videos!
I used to work with three phase power on commercial airliners where it very useful for instrumentation and for high power. Mostly on 400 cycle systems syncrotels and control servos etc. I had studied an electronic engineering course for 3 years at Miami/Dade college.
I work for the utility industry. We used galvo to check phases make sure the cables are connected right and no cross phases. Am kinda a highly school train doing work where minimal training is needed. When tracing current is comin from the station we used +a+b-c.. just to differentiate on the field low level to the transformers. When cable fail they usually send high voltage of 30 frequencies . Just want to add my 1 penny
Tesla invented the three-phase, 6-wire motor and the two-phase, 4-wire motor. But the high number of lines prevented success. Without knowing about Tesla, the Russian Michael Dobrowolski in Germany perfected the three-phase motor with three lines as we use it today. The first application was an 8000 volt high-voltage line from Lauffen to Frankfurt. Two transformers, a generator and a three-phase asynchronous machine were used for this purpose. Dobrowolski had improved the three-phase motor so that it worked, in contrast to the Tesla patent, which remained in theory. So Tesla patented the 4-wire motor (two phase) and 6-wire motor (three phase) and Dobrowolski got three-phase motors running in Germany with just 3 wires
I enjoyed this video. It all seems to make sense in the context that you explain, but I'm still stuck trying to find an on-ramp for this material. Why are angles a part of this at all? How do angles relate to magnitude, and what is magnitude in this context? I hope we can backtrack in future lessons and explain some basics.
Read something somewhere once where 6 phase AC was discussed. Same principles but!! It would be more effective for motors and transformers, but again why?? For 3 phase - 120 degrees apart and square root of 3 for actual power purposes, is all that's needed to understand 3 phase. One can reconnect a 12 lead 3 phase source to emit single phase. There are also single phase powered 3 phase converters. Not very efficient though for either. Lots of loss in the form of heat. The US Navy during the early submarines, used a 60HZ 120 / 120 3 phase floating wye AC distribution system, to power the boat. No matter what you touched it was 120 VAC to neutral or 120 VAC phase to phase. It was then converted to DC to charge the batteries and run the drive motor for the propeller.
Explaining how a 360º circle is equally balanced in 3 parts when divided by 120º - FOR HALF AN HOUR. Thanks God I made it to the last second without yawning.
So basically because 0 degrees and 360 degrees are the same thing we measure -120 degrees and +120 degrees from the reference of 0. Circles are such a beautiful thing when applied to everything.
That's why Gaia assembled her Avatars as 3 Pole Triple spiral DNA, that lights up each pole to run,positive,positive positive to create a Tesseract hyperdrive Merkaba that supports teleportation with all the original DNA blueprint chromosomal data functions.
We could eliminate tranmission if self power special medical equipment or critical system like pacer or time keeper prevention of influence outside. So piezoelectric may open new road then convert it into internal 3 phses for memory data
I came across a oven yesterday that had had line 2 and 3 switched. It should just cause the motor to run wrong it wouldn't cause the three fuses to blow would it. I wired it correctly replacing the fuses today. Replaced the transformer yesterday thinking that was the short in the system blowing the fuses noticed the wiring after that, elements all checked out fine. The only thing really remaining is the wiring but I'm not sure line two and three being backwards would cause the fuses to blow. It could have been the transformer just commenting for some insight before turning it on today
If you are interested in going in through a 3-phase video series from a single tutor then be aware that this video series is paid-to-watch after the 2nd episode. Go to Kahn or whoever else right now and don’t waste your time.
no mention of Delta and Y winding, they are vastly different and the outputs as 3 phase are the same but if you us a single phase be ready for some changes,

I worked in a textile mill years ago and most everything in the mill was 3 phase. You don't need a start or run capacitor on a 3 phase motor.

Thanks for the tip!!! Greatly appreciated.

I thought a capacitor was to put the current out of phase which gives the motor additional torque to start,

Maybe I somehow had the foundation and didn’t realize it. I still feel that they try to make the math that is easy into something complicated.

With a little theory background he is very precise with his tutorial.
Thank you very much for these videos, they're real treasure.
Thanks for all these great videos!👍👍👍👍👍👍
