Electrical Engineering: Ch 13: 3 Phase Circuit (4 of 42) A 3 Phase Generator (6 Coil) 

2023 and still the best lecture series for electrical engineers professionals and students alike. Thank you Michael!

Haha I love how you just calmly finish the video with the cat in the background. Thank you as always.

I spent hours looking at many tutorials to figure out the most fundamental thing you didn't mention! Which is this: I discovered that the maximum point of flux produced by the rotor is at 90deg to the N & S pole ends, which is why there's no voltage produced when the rotor pole ends pass over stator coils at 60 deg apart. Hence, now explains why the waveforms are 120deg apart, not 60deg!

The first teacher who explains the magnet position according to the sinus curves in a right way by mentioning the "change of the magnetic flux" at 2:00 - Thanks

Mr Bieze dont need sleep.So many videos...I Just thank him.

This is the cleanest generator winding video I have seen on youtube so far. Keep up the good work.

Your smile at the end is so wholesome, it made my entire day better. Thank you for your contributions to human knowledge & learning. :D

Excellent explanation! I've been curiously digging into learning to make my own generators and especially was interested in 3 phase. This laid it out very cleanly and effectively. Thank you for putting the time and effort into this and sharing it online!

Awesome video, that helped a lot. Thanks.

Dear Michel, thank you so much for your very clear explanations. I sometimes consult your videos to get inspired for better and focused explanations in my own teaching. Of course, I refer to you.

@Michel van Biezen will the efficiency of the generator increase if the stator cores around which the wire is wound are hollow, like a pipe, because then the magnetic field in the stator will be more near the wound wire, around the sides, unlike a solid rod where magnetic field will be distributed along the cross section?

Sir i have a question. Is it possible to get only 240 volts from the output of a 3 phase transformer? While my input wiring is 3 phase 360v? Because I'm planning to buy a 3 phase ac generator dynamo and at the same time i want a 20kva 3 phase step down transformer. Is that even possible?

I am trying to wire a 3 phase generator to single phase using the Twelve wires coming out of the generator wires 1 and 7 are connected to a load wires 8and 2 are connected to a load wires 3 and 9 are connected to a load wires 4 5 6 10 11 12 are all grounded. Do I split 8 and 2 and connect 2 or 8 to 3 and 9 and one to 7and 1?

Excellent. I was playing this over my sound system. I thought that was MY CAT for a minute. :)

Thank you so much sir. One doubt sir flux is actually cutting north pole side (flux is going to North to south) therefore the induced current is produced by North pole side coil only and next 120 degree to produce negative half cycle in same coil because north pole is opposite coil side..... is my concept is correct or not correct sir?

great videos, short and very clear

Thank you

Amazing sir..

Great job and nice to hear kitty meowing as a bonus.

Good explanation. Will be back for more

How many poles does this generator have? and the coil shouldn't be 120 degree different?

Plz sombody share a link from where i can understand generators neutral. That whats its function and how its work in animation

funny yesterday i was pondering how to connect my 3~coils (12 as in 6pairs) with the voltagediagram while evaluating how much voltage my setup might turnout, thank you algorithm and thank you mr. van Biezen for the insight

Great video and well explained

Great video. One question: how are the opposite coil connected to it's "partner", and is the coil wound direction different from the opposite coil?

Hello, great video, can you possibly tell me what factors involved in a magnetic field passing through a winding dictate direction of current?

is it one clockwise and other anti clockwise

شكرا أستاذ شرح رائع و مبسط .متتبع من المملكة المغربية

I enjoy your teaching a lot, greetings from Mexico, one question, when the magnet is pointing to any coil, lets say North of the magnet is pointing to any coil, at the same time the south of magnet is pointing to the secon coil of the same group, how is that, because in some other videos, they say that the same polarity of magnet need to be acting on the coils at the same time.....hope you can find some time to help me on that, I send you my best wishes!!

Why the synchronous generator stator is Double star connection?

Hi, I'd like to ask about at which pole position the generator can achieve its peak voltage. Why does it different with the 3 coil generator? The 3 coil generator seems to have peak voltage when the pole is parallel with the coil, but in 6 coil the voltage reach its peak when the pole is perpendicular with the coil

Thanks Mr Van, it's clear now

Nice sir 👌👍👌👍👌👍👌

Very good video I like very much.

I don't get it. I thought at North pole approaches the coil it starts to induce voltage reaches it's max when half way to the middle of the coil and at zero when it hits the middle of the coil. Then as the north pole is pulling away from the midde and out of the coil the phase is at max negative value. So one full phase is realize in your diagram by the magnet simply moving 2 inches, just approacing and passing out of the phase one coil. I was also let to believe a south pole will cause current flow in the same way but opposite direction. AM i wrong? If so pleasee help me iwth why and shoud the coil windings in this set up be going in opposite dirctions. For exampe one coil is wound clockwise and the other counter clockwise.

Shouldn't there be maximum positive or negative amplitude for a coil when the magnet edges are pointing to it?

Should the coil be wound the way you're showing or big coils with one side on 1st and other side on 4th slot?

How many volt and ampere we have to fill the rotor that it has a quite large electric magnet to produce 220 volt?

Oh dear, I'm so confused. Isn't the flux equal to BAcosx? So when the magnetic field points directly through the windings(as drawn), its parallel to the red coil right? So how does the change in flux end up being 0? Should'nt it be maximum, since cos(0) is 1? I have a feeling I've seriously misunderstood something. I'd be really grateful if someone could clear things up.

Thank you.

Why would there be 2 coils per line? And why are the 2 coils are directly opposite of each other?

Nice video. Congratulations. But I didn't understand why the Emf = 0 when the magnetic flux is maximun in the coils. Could you please explain it? Thank you.

I didnt see if you mentioned the direction of winding for poles (say for A) one pole is wrapped clockwise and the other is counter clockwise. Very important for a sinusoidal input.

your finger moving not make me clear clockwise or anti clock.pl clear me.

Im having trouble understanding why the neutral is connected to the phases.

Someone answer this, if the neutral is a coil and the magnet S\N giving it a flux so why the neutral does not act exactly like a phase, could someone please explain it what is the difference between phase and neutral in this graph

Wouldn't the voltage of the red at point (1) be at the maximum, not zero? Since the strength of the magnetic field is strongest at the red at point (1). Why not?

How many times the current flows out in each cycle? Looks 3 times per cycle?

How do you teach everything? Excellent !

Danke

Sir i am from pakistan... I am a student of B.S Physics...your lectures are very great full...Thank you...

Simple and quick question, to recreate a quick charge for a Tesla with using a 3 phase generator that's equal to the quick charge system, what hp motor would be needed in the drive motor to turn the 3 phase generator? 200 +?

First I would like to thank you for your efforts on these videos I learned a lot from this video but I am 99 percent sure your graph points are placed incorrectly and I am commenting for people trying to learn this so they dont get confused. When the poles of the magnet are near the coil the force is the strongest and the voltage will be the highest. When the poles are perpendicular to the coil it will be the lowest. Point 1 and point 4 should actually be the maximum positive and maximum negative voltage points on the graph for the red phase C. I saw where someone said point 1 is zero because the magnet is not moving. If this were true there would be no voltage on the other phases as well. But from the graph the magnet is obviously moving and when it approaches the coils the voltage is actually the highest and also the lowest. It is 0 when the magnet is perpendicular to the coil.

Is that cat okay :(

If the coil wire touch each other ,then will it not work...? Right..!

Wow...

AA

The cat is complaining about being lost

That kitty is saying "out out". Apparently she's bored of EE topics and would like to go outside.

Awesome video, that helped a lot. Thanks.
