Damn I love your videos man, so easy to follow and you make everyday things so fascinating.
i invented a electric car with five wheels, use the fifth wheel as the alternator to recharge the battery but i don’t know if it would turn fast enough 🤔🚗🔋 the alternator would be on the road, it might drag the performance down 😐🤷♂️
i subscribed to your channel but i want to ask you something
*why and how short circut happen?*
@@DonaldSleightholme better to use connect alternators to the engine instead of using fifth wheel just for that purpose
I'll buy you a couple Starbucks coffee worth if you do basic HVAC ladder diagrams and schematic energized animations. Even a basic HVAC circuit board would greatly help engineers and HVACR tech's alike. Thanks for all your hard work in your videos Paul 🍻
You've explained 3 phase way better than my robotics instructors! Good job!
Glad you liked it!
animatated videos are much better than chalk and blackboard
now that's electrical engineering
@@tintinfan007 agree i now fully understand what happens on them besides the fact that they make power. lol
Same. Why you need school when you have “The engineering mindset” CZcams channel
OMG!!! No words. This 18-minute video is way too much informative than my 2 years in high school. Never thought electricity could be this much fun.
Keep it up guys. Keep educating and keep growing!
Glad it was helpful!

Yes, Der Steppenwolf, electricity is BEYOND fun; it is the basis of ALL we see as 'REALITY.'
Yeh more informative than 3 years of electrical engineering that i studied 😝
@@tomboytomgirl5356 Q
QQq
can't believe i'm watching this for free while i had to pay for my engineering degree.
but you can't apply for an engineering job with youtube's certificate
I'm not an engineer, I do engineering stuff as hobby, that's why I watch this video
And thats why we're all doomed, i would much rather hire someone that seeks knowledge like you instead of yet another bot coming off some college because "he has to" and "engineering" seemed cool
Well I have a masters degree in mech engineering, and I still watch these videos to gain practical knowledge about existing solutions. Degree gives you theory. principles and knowledge about ways of designing stuff. These videos give that practical knowledge that you dont really get from universities, but if you want to calculate the thermal expansion of the engine block under load, a fitting degree could be quite useful in order to validate the results. Hence the importance of a degree should very much vary depending on the specific needs of a company.
Good lesson!
@@CitySwimmah well said, well spoken 👏🏾👏🏾👏🏾👏🏾
I am a former college electronics department instructor, you do a good job explaining basic concepts without going into the mathematics. I think this is how students create an interest in electronics.
Hey man I'm interested in electrical engineering and was just wondering if you had any advice for me. I've never been to college but I'm mechanic apprentice and was also wondering if there is more things to teach myself about electronics in a vehicle.
@iwishtobetexan6060 Well, there is obviously a lot of electronics in vehicles. You can learn about microprocessors, ac/dc motors, transformers, digital circuits, analog circuits, and some of the basic chips and how they are typically used.
Once when you know how all the parts work, it's honestly crazy how simple this setup actually is considering how clever it works.

This channel is soo underrated.
I’ve been trying to wrap my head around 3 phase power generation for years! Im a hobbyist, so I’ve never really studied it, but as with a bunch of other comments I read, you explained it way better than any resource I’ve come across. I can now say I have a basic understanding of how 3 phase works!! Yay!
Thank you!
There's no better place to learn about 3-phase than by watching videos about DC power generation!
This is without question the best explanation of three phase, rectification, and regulators I have ever seen.
Exactly what I have been yearning for....thank you Engineering Mindset.
Glad to help
great format
The way you showed the phases and then turned into DC , was absolutely one of the best you tube videos on it i've ever seen , Great work !
There is something satisfying about the -ve flow electrons in every video for precise demonstration
I will never forget it now lol
AS a former lecturer in electrical science I commend your brilliant produced explanations of 3 phase without the encumbrance of mathmatical calculations.
I wish our teaching plan was more in line with yours !!!. In another life you could have shared the Royal Society lecture hall with Mr. Faraday ..thank you
Electrical science? I've never heard such a course. maybe elec eng.
@@davemwangi05 No...this was a course designed by Prof Derek Williams and I took part in it's delivery where we took the practical aspect of electrical engineering and examined the subject from a scientific approach...a bit different but turned out to be very sucessful.
@@georgestyer2153 Oh okay. And here's this eng challenge that has always puzzled me, and I ask people and they seem puzzled as well. You know that case of current passing through a solenoid? We know that if you open the switch at time t, the magnetic field will collapse and generate a spark. Now, if such an inductor is placed in a vacuum, and then one opens the switch when it's 'carrying a high current, what will happen? and we know one cant destroy energy or create it. Really interesting question, try figuring out and tell me. or you already know the answer in your fingertips.
I find myself coming back to this video again and again to remind myself of how this important component works. I had no idea I was generating 3phase power in my cars' alternators. This is great stuff. Many thanks for this vid.
I agree. 3-phase surprised me
There is some seriously good teaching material on this channel. Colleges should take note
A civil engineer specializes in structural design, now knows EE and Electronics basics in 1day watching in CZcams. Thanks The Engineering Mindset.
The quality of this series is absolutely superb, one of the very best edutainment channels. Thank you!
This is insane! what a simplicity! You made it so easy to understand as always, that's why I love this channel, thank you so much ❤
Great to hear!
❤️❤️
Super great visualization. You guys have helped me gain a greater and greater understanding of electrical theory and components over the past couple of years. Keep it up!!
Videos and explanations like this should be mandatory on engineering colleges. Excellent! Many thanks!
These videos are well done. I never knew how complicated a car charging circuit was until seeing this. Thank you! I think my favorites are 3-Phase Motors and Star-Delta controllers so far.
The fact that you show electricity as the actual transfer of electrons rather than the flow of current is super refreshing. Great job.
How can you even create such an informative video and have it be just 18 minutes long. This would have taken forever to grasp at school or by reading online... Super good job! You explain and show things so well!
Came for an alternator in depth, instead met half of the electricity basics. What a video!!
I’ve a BS in Chemistry - and didn’t understand 3 - phase power until now. Thank you for a clear and concise explanation!
You explained deep theories in a simplified way. Thats great
Your videos are always awesome. I know how much it takes to draw, animate such thing. Welldone, u r truly appreciated mate !👍
Love the way they explain things so simplified and informative
That was very simple and cleared everything up. Thank you!
*I LOVE* the lad's accent and voice. And, of course, this is a great explanation, as always.
Happy that you take the time to make this videos. They're super educative.
This literally has to be the most informative and simple ways an alternator has ever bee been explained. To me anyway, I have a hard time understanding electrical but man, not anymore this was a real help
Best exlpanation for the altenator that I have ever seen or hear!!!
These illustrations make me fall in love with electricity again and again 😍
Glad you like them!
Thank you for this, I have just self diagnosed my car issues that have been plaguing me for months. It's the bloody alternator. Cheers
Bravo! Fantastic demonstration on how an alternator functions and your animations were superb!
I was just wondering this while driving home the other night. Thanks
Seriously the best Engineering content out there!! Keep the good work going!!
Brilliant video, wish I had these videos 30 years ago when I was studying electricity.
OMG Phase was explained in the most pragmatic and simple way I have ever seen on youtube and iv'e seen alot of youtube
Hi The Engineering Mindset, Great video you have produced here, I really enjoyed it, great content, great animation. I particularly enjoyed where you made so easy for non technical persons to understand. I felt it was really informative and you really brought the point across well. I am really interested in engineering and have had a career in engineering for over 28 years from everything from starting as a mechanics assistant to now a Project Manager. I enjoy sharing my skills and knowledge as well with others like yourself. I have provide training to others and had apprentices work with me to kick start there careers. Many thanks, Great job.
No words. You guys at engineering done a great job for humanity.
Superb! The lightbulb went on at around 7mins once I twigged what the electro magnet was doing (damn clever!) but the fuller explanation was greatly appreciated, especially around the phases. Thanks truely excellent video!
Paul, you have been a great help over many electricity questions.
In my home little kids of 12 years are there they can get minimum knowledge by your videos sir
Kudos keep it up!!!!☺️☺️☺️☺️☺️☺️
Congratulations for 1 million ❤️
Thank you!
You answered what I've had trouble understanding for so long. Thank you!
brilliantly explained man... appreciating your hard work
Great video! So well described and explained.
Damn GOOD! explanation. Pity we did not have The Engg Mindset (& CZcams) when we were students eons ago.
Such a well explained, i had this video in my suggestions for a long time and now i finally clicked on it and it blowed me away. Good job, keep them coming.
*blew
The best tutorial ever!
Bravo.
Your way of explanation is fantastic and your animation is to good
Thanks for making this video
Thank you!
Brilliant video as usual! Could you do automated voltage regulators for a generator?
and now I finally understand AC and DC and how it is generated.
Thank you
just love how this channel simplifies complex topics!
Gosh! I graduated with a bachelor of electronic and telecommunication 4,5 years ago. I completely changed my life since then, ending as farm manager. Have some huge old mill here. Always thought about running it as a hydro plant, but I missed 0,1% of the knowledge required to build my generator... You did it! You filled my missing bit! It's sooooooooooo amazing, cant wait to build it :D If it's gonna work you'll save thousands of tonnes of carbon footprint ;)
Nothing wrong with carbon!
This was a most excellent presentation...it was very informative and entertaining..definitely a 7 on a scale of 1 to 5. Thx so much 😎😄👍🎈
Now I understand a lot more about alternator. Thanks for great explanations.
I would love watching and learning more on electrical components in a car♥️♥️
Brilliant timing! Love your videos, thanks for taking the time to produce them
Glad you like them!
this is mind blowing, how we can support you fella?
I can’t even imagine creating these 3d models 🤯 great video man!
Perfect explanation now it turn my toughest lesson to easiest. Thnk u so much.👍
Now this is what I call an education 👌
Exceptional work with exceptional animation and pictures,
easy to understand,very analytical,leaving no blank spaces.
As we all know how much hard work is behind this task of videos and explanations,
a big thank to you is the least we can do.
Very good explanation..complex things made very simple that some people takes years to understand !! Great work.
Very good video. I learned a lot. I had to replace one recently in my car so its good to know how that works and why was it so important to the car.
@The Engineering Mindset ......u r a god level explainer with such simplicity ......the way u explained 3 phase AC was ingenious....love ur work bro...a huge fan from the past....keep teaching us .......U R THE BEST.........
Very glad to hear, thank you

why i found it now damn i must to watch your all video can't believe this is free thank so much keep it
The video was so smooth, the way he explained, I wished the video never finishes.
Somebody has a crush! oooOOOoohh!
Fantastic overview. Wish I had seen this 35 years ago...would have saved me a lot of head scratching 😀 A little mystified at the mention of the capacitor @ 14:36...perhaps it’s mentioned in the interest of aiding understanding. Thx! Great piece 👍
The capacitor charges up with the voltage, and when the voltage is dropping, it discharges to keep the voltage up. This makes smoothens out the waviness. The higher the capacitance, the smoother the output will be.
Also, I agree, this was super helpful.
@@MrCoolerMan1 Hello... totally understand they mean to imply it’s a smoothing cap and for a description of operation all good... But you will struggle to find one in reality on an automobile...at least all the vehicles I have owned over the years...Cheers
Your explanation is wonderful. Thank you!
This is without a doubt the best and easiest way to understand how an alternator (or generator in GM speak) works! I wish I had this when I went to automotive training many years ago instead of how and what was taught back then!
That is rightly an ingenious engineering explanation. Only those who understand the basics can explain it well.👍
👉 Most of the teachers have no idea and they sell it as a doctrine.
Good video as always, but there's one thing that I think should have probably been changed as it gives a wrong impression of how the car works in general. When talking about the regulator, it was stated that, " the output voltage of the alternator varies with the speed of the car", and "the faster the vehicle travels, the faster the crankshaft rotates." This brushes over the fact that the speed of the car, and the rotation speed of the engine are not directly linked.
A car can be moving at the same speed in 4th or 5th gear, but the difference in gear ratio will mean the RPMs will be drastically different to compensate, which will cause the alternators shaft to rotate faster or slower, changing the output voltage. Changing, " the output voltage of the alternator varies with the speed of the car" to, " the output voltage of the alternator varies with the speed of the engine". Obviously doesn't require explanation of the transmission, but it also does not cause confusion by directly correlating movement speed of the car, and rotation of the engine.
That's a valid point. Maybe I can link this in as I cover the transmission gear set

Thank you very much !
That was so clear and well explained. Instant subscription.
Every time you talk calmly about ‘’ full bridge rectifier’’ l hear ‘’FULL BRIDGE RECTIFIAAAAA !!!!!’’
a goldmine of quality content. thank you
The 3years I been electrical engineering never understood the wye system the way I do now after watching this video. That it’s a shame how it’s made do difficult to learn basic fundamentals these days.
I studied 4 years in college but I didn't understand how AC current and.magmetic field works until now. 😅😂
Excellent visual presentation. Thank you.
The best aternator education that I have ever come across... many thanks.
Great video, but here's a couple of small criticisms: 1. "diode trio" is a bad term to use, a proper term is "half bridge rectifier". 2. The reason for using a half bridge is not explained in your video, but it's easy: it's there to prevent the battery from draining when the engine is off. It's a very nice way to passively and reliably control the flow of power. The current returns through the main rectifier, and you only need to use a half bridge to isolate the field winding from the battery. Some alternators rely on residual magnetism of the core to start producing power, this is why some cars need to be revved at start up for the alternator to start producing power.
G'Day Alex,,yes you are right,,but the reason you rev them is to charge a capacitor in alternator to supply field power to the Rotor,,once yo get a couple of volts charge in the cap,then ya ready to charge,,and the other systems take over,now we have the charge to excite rotor wingdings,,
I don't think so, , the cap does not hold a charge to start the system. it's the residual magnetism in the rotor which excites the system. it's not a refrigerator . That cap is only to block radio interference.
In today's alternatives the voltage regulators are inside the alternator. In much old cars they were separate from the alternator.
They also used a more mechanical way of regulation, bi-metal strips with resistance wire around them that switched the rotor winding on and off
Thank you “Engineering mindset “You explained it so well.Again,,,Thank you so much 🙏 ...
wow very detailed video. I like it. I can it understand perfectly even though I speak almost german. Thumbs up.
Nobody:
Me thinking about how my brain send me electricity when i need to pee...
You just sent electricity to make my brain realize I need to😱
objective
What is the minimum RPM required for automotive alternators and what determines that?
Good question, it will charge and produce 14v while idle but I don't know the exact rpm below which the voltage is unusable. There's also voltage drop through the diodes.
Firstly the warning lamp, normally 5 Watts, the "Cut-In-Speed" is determined by the amount of current and the speed of the alternator. Imagine that the current is limited through the rotor by the warning light, as the alternator spins, this allows the currant to become stronger due to the production of currant, then the warning light will extinguish as the rotor has full currant (3-4 Amps), then cut in speed is reached, some 900 Alternator RPM and not engine RPM as the pulley is smaller than the crankshaft pulley, if you want the alternator to cut in earlier, simply put a bigger bulb in the warning light, thus higher initial currant to the rotor QED cut in speed lower engine speed. Not to forget that the alternator is taking BHP from the engine, higher the output, the more it takes, turning the alternator without output can take 2 BHP, depending on what you are doing with it, I guess power plant to charge batteries then inverter to power the home. If you can find brushless alternators (CAV ) used some in military applications 90Amp quieter and no parts wearing out except bearings. I see many projects on the internet using car alternators, putting permanent magnets instead of wire-wound ones. The capacitor is purely for interference and not for balancing the peaks and troughs, although it does do that to some degree . Hope this helps
