One of the best (and simplest) explanations I've seen!

Guy you are my original teacher for induction winding.Salute sir.

this demonstration qualifies as a piece of art, not just the psychedelic coil, also the dreadful computer voice ("just kidding, that's crappy!") combined with a reassuringly human voice, proving your professor wrong, testing your fields to the limit with that delta configuration, and the text annotations. Classic!

the guy actually sounds like the scientist who goes like "Gordon, What have you done?"

"Professor don't know shit, I'ma show you what happens" I love watching these... I feel like I might learn something someday

Good video, I myself love seeing these sort of demonstrations. Would just like to make a correction as to how the flux lines where described. The flux lines do not pass through the centre of the can in a straight line as described,as basic physics stipulates flux lines never cross. The flux is actually moving to the pole adjacent to it, basically, as he described for the 3 coil experiment (the flux lines are guided/attracted through he tin can because it has a lower reluctance than air).I suppose it would look cool if you placed a piece of paper over the stator with iron filings, and you should see them. This is why the motor spins slower when there is more poles. After he reduced the number of poles, he has effectively doubled the distance from one pole to the other, since the flux density is proportional to distance, the flux density is 25% that of the 6 winding design, which explains why it spun slower. Also, I think what the professor was saying is that if you increase the distance between the stator and the rotor (the air gap), the motor loses power, or becomes less efficient. You experiment worked because it was unloaded and didn't require that much power to turn it. If there was a load connected to the original wide can, I bet the smaller can wouldn't be able to develop enough torque to turn it due to the loss of power (remember, air has a high reluctance) over the larger air gap.

Oooh, that`s very interested, Good Job guys

Nice build! Looks like you put a lot of work into that, good job :)

There's a rotating magnetic field around the coffee can. The direction that this field rotates determines the direction the can rotates. Essentially the can is trying to catch up the magnetic field at all times.

thanks bro just because of u i came to know how AC motor works thanks alot.

pretty good demonstration :) helped me with my physics assignment~ thankyuuuuu~

what happens when rotor weight is more,?

Gracias por tu video saludos desde Lima-Peru

This is actually pretty sweet! ;)

It is very nice demo. Thank you and youtube who brought so much practical knowledge to us- Kamlesh Singh Raghuvanshi

Nice project!

Hello, thank you for sharing your project, I have a quick question, what's the input voltage into the project from the 3-phase supply?

i had a dreamed that look like that once...

The time is 3:42 Am in the fucking morning, god damn these videos are cool!

this one is really vry attractive nd knowledgeable tutorial. so thanks

رائع جدا شكرا لكم على المجهود

good project,thanks.

Great job my brother!! : )

Do all the neutral connect together with a wire-nut or connector? And did you run 3ph AC? Im wondering if I take the C connector and put a run capacitor on it then just run single phase power it should run as well because the capacitor will provide the phase shift.

Is this same principal applied on 3 phase linear motor

Watching it at 10.19pm 25th of December 2020, happy Christmas 🎉🎉🎉

@hapmyster Ah other way round. More poles means more torque but less speed. Less poles gives more speed but less torque. Motor speed = 120F / p where f is freq and p is no. poles.

very nice video

If you look at a real rotor in a motor, you will see impregnation of aluminum or copper. This will act as a short circuit to changes in the magnetic field in the rotor itself. When you oppose change, the magnetized iron will tend to remain the same and that is most likely why you couldn't get the rpm up.

If someone could help me out on this it would be greatly appreciated. At 0:08, when it shows the diagram, does "A" "B" and "C" all come from different power supply's or the same such as a series of batteries? Also, does "Neutral" just mean the ground? Thanks.

Thanks a lot. Explain about rotor winding.whether it is 3 phase or single phase. And it is squirrel cage,or slip ring

That's a nice motor

I know this is really old, but I'm curious whether the rotor would achieve higher rpm (and torque?) if 40% or so of the metal mass on the walls of the can was removed by cutting away even, vertical sections. To me, it seems like you have to consider the less than optimum weight of the can, where the metal is actually quite durable so you have a lot of leeway to remove some mass. How would that affect the magnetic force on the rotor? I think the video would have been that much more interesting and maybe a bit informative if you removed some metal from the sides and top of a can and discussed the effect. I wish more ten minute videos would run a little longer and elaborate on their subjects.

3 phase is just like regular 60 Hz AC but is has three lines and alternating currents on those lines are offset timewise. When line # 1 is at 120 Volts, for instance, line # 2 and line # 3 will be at -50 Volts with line # 2 voltage going up and line # 3 voltage going down. Basically, you have peak voltage on any of the given lines every 1/120 of a second instead of every 1/60 of a second.

This idea came from Nikola Tesla in 1880.. The person who electrified the world

im interested in this video..can u upload a clear layout on how to install the 3 phase wiring or they called it diagram?....thanx jim....

Nice job!!

Separate AC power supplies, where each one is 120º out of phase. Or simply put, it comes from a 3 phase AC power supply. Yup Neutral means ground.

good job

Given that 3 phase power is used in this demo, would this motor be termed a 2 pole motor or a 6 pole motor? I am thinking that 3 phases connecting to three of the transformers is ONE pole, and the same for the other three transformers makes a second pole.... ie 2 pole motor.

At time 5:40 i was starting to trip out... Lol 😹

4:55 you're getting sleepy, you're getting sleepy.

Sir, I just wanted to clarify...Does it need for the turns to be equal in each coil ? I badly need the answer, please.

can we reverse it..and make a generator at 120 out of phase 3 phase?

those are some fast hamsters, lol

very nice

How does the coffee can start spinning to begin with? Don't motors need actuators or a push to start them up?

Awesome!

That depends on which of the three phases turns on first, second, and third. You have three phases. A, B, C. If A has a phase of 0 degrees, B has 120 degrees and C has 240 degrees with respect to A. In this case the motor would spin from A to C because A turns on first. It helps to see a picture.

Very Loveful video

Hey Jim can you do a video on which wires to connect to each transfomer? I see that schematic is simple what if you wanted to connect more transformers like 12.which wire will you conne to?

we need to get you some bearings and balanced weighted rotor!! : )

What is insde the can please'?

How many turns each of coil 🙏

Sir,please give details about wire gauge and number of turns

What is the rating of this three phase induction induction motor..?

Very nice... Can you just explane me how do you calculate number of turns for each phase? This video is very helpful.

Was it synthetic 3-phase? What frequency of 3-phase power was applied? Great video, but a little more of the background facts would be nice. Maybe add as captions?

All electricity is "produced" at a power station in 3 phase's, then it goes to substations and is "stepped up or down" in voltage but remains 3 phase, even in your street it is 3 phase which each house draws a different 1 of the phases that is why sometimes during a power cut at your house. Some others (2/3rds or 1/3rd) may still be on in the street. As for 3 phase motors they are mainly used in industry as they consume less power than a same HP single phase and are more powerful torque wise

in that last part, there was a buzzing sound.... doesn't that mean it was AC? not that it wouldn't work with DC because we're attracting a can with iron in it, but the buzzing was probably AT the AC frequency, and was essentially the vibration of the can reacting to the field (essentially, the same thing as a speaker)

@kingfaisal550 Well, sort of. This is not any free energy generator/ motor if that's what you mean. The constant switching on and off of electricity from a power source to a coil causes a temporary magnetic field, (which lasts about a fraction of a second) which spins the rotor.

+jimbob Are there magnets behind those can walls?

How do you have all of that equipment available for you. Is that where you work or your own personal stuff? I am extremely interested in working with motors and motor controls and I guess im just wondering what you do =D

Good engineers, tnx

Hey, great video.. I'd like to do this project for school, but I have few questions... How many windings do coils have? And is there any magnet or something in/around that tin can? Thanks.

what did u use to find the rpm & how much does it cost

how could we fix the number of pole in induction machine as 2 pol ,4pole......??

GLADOS DOES THE INTRO

thank you, very good indeed

Nice.

Cool video. I have a few questions if anyone knows the answers? If you added magnets to the interior of the can would it spin much faster? Also, if you did use the magnets and spun the can by wind or water to generate power would you just merge all three phase ends of hot and the three phase neutral together to combine the power generated? Sorry for the basic question, i've been trying to learn more about induction motors and generators and would like to try constructing a simple generator.

Does enibody know hot to calculate number of turns of wire in each coil... Thanx a lot

are the connections at 0:10 drawing correct, shouldnt the 120 degree ones be grounded together, you have grounded the adjacent connections instead of the ones that are 120 degree apart.

i like this

Cool

Great vid , nice experiment and prac . My only opinion is couldn't you have just given the intro your self instead of a CGV =/

If I wire it like this can it be used as a generator if throughout in reverse

Single-phase induction motors do, three phase ones don't because the timing of the phases creates a rotating magnetic field.

put an magnetic band on the rotor,

nice ... tell me about the minimum air gap between stator and Rotor , regards

if the crt & other parameters w.r.t RPM is shown quiet it was a such a good exp

Whats inside the can? Permanent magnets??? wires?

Nice!

this is an eddy current motor, not an induction motor as the term is defined in engineering. though eddy current is of course generated by induction. note that there is no squirrel cage winding in here

i would like all lesson on youtube that you provide

Is this similar to the way Tesla motors their cars? Are appliances (sorry if that's just the word for toasters) like the one you have created in any form patented?

0:08 Where to the wires A B and C go? Could anyone explain to me in detail how to wire A B and C further?

This automated train is provided for the security and convenience of the Black Mesa Research Facility personnel

I already did that. We didn't get to do these kinds of prjects though =(

Get in a technical college program to start off with. I am in a 6 quarter tech college program that covers residential,commercial, and industrial aspects of working as an electrician. We have every utility company, IBEW, Boeing, etc. who recruit striaght out of our programs. I am in motor control class right now. This is what we do and study. I work as a resi/commercial electrician apprentice. You don't see this at work. Go to school!

Does each magnet have a different charge(+ & -)?

great but you have to make some mechanical modifications on rotor good luck

It is good Demo regarding 3 phase Motor.

Hahahah no credit was given to professor Osorno xD

it was a set up, D: he's trying to use hypnosis to control you, don't look! hehe neat vid, thought it was awesome

HOW DO YOU FIGURE IT IS A 2 POLE?

Standard 3 phase motor.

What professor told you the force is upwards?

You did not connect the six coils in a delta! Wye not?

interesting...
