Can I buy this device you’re using as both generator and motor?

[@CG-rc4ox]

Hi Paul, Thanks for this explanation. I completed my BTEC in electrical engineering and we touched upon AC gen/motors, and DC gen/motors, I'm an apprentice so I'm still learning, I completed the generator unit in my BTEC around 1 year ago. I have a burning question. I work with AC generators which are ran from a diesel engine- so the camshaft, cam gears and a driving belt and is connected to the rotor (which is the coil) and this is slotted into a stator (magnet/electromagnet). The rotor is spun via the camshaft which then in turn creates AC electrical energy due to the stationary magnetic windings. The stator goes out to two slip rings which have carbon brushes which then connects to the load/cables etc. In DC Generators are AC generators but with split rings? I can make an AC motor by placing AC electrical current (i.e. a plug and wire) into the rotor which causes the rotor to move and creates mechanical energy rather than using my hand to spin the rotor? Similar to DC motors but a different commentator arrangement and DC power i.e. battery etc. To make it even more complicated the engine is started via a motor and a starter battery. So DC power is input into the the rotor via the starter battery which causes the rotor to spin which is connected to the fly wheel. The fly wheel turns the shaft which enables the piston to go up and down (whilst they are being filled with fuel and air). Also, with an electromagnet formation in a car for instance, will the electromagnet receive it's electrical supply from a battery? I'm just wondering if that is correct?

[@thebigdintown8349]

you're doing this for electrical engineering?! Dude, I'm learning this for a simple year 9 physics test 😭

[@ChillCat665]

You asked a lot of different questions there but I can answer only a few. An automobile uses air/fuel to move by exploding it with a spark or glow plug that is powered by a coil powered by the engine but to start the engine an electric starter motor powered by a battery is used and once the motor is running the starter battery is charged. Fuel powers most cars because fuel is much more power dense than batteries and even electric cars get most of their power from gas or coal depending on what is used in your country. Wind and solar are only a small fraction of power generation and although people think wind and solar are "green" energy choices the truth is the construction required to build them impacts the environment harder than gas or coal power. The most environmentally friendly power generation is nuclear energy. Our power grid uses AC because DC can only go around 12 miles without power losses and AC can go hundreds of miles and if we would have went with Thomas Edisons plans instead of Nicola Tesla we would have power stations every 12 miles and the landscape would be much more cluttered up. I hope that answers some of your questions

[@azizrani8148]

really perfect explaination...but i dont still understand..this video is using 2wire for output source...what about single phase motor ..that apply 6wire for output..and can u help me to understood.which one is 100v or 220v output../12v output and which one is using for capasitor..???espeacially when i do the modifidecation for induction fan motor....and really hope can make video or explains about it... #knowledge is for sharing...😆😆😄😄

[@uriaanduplessis4124]

Why doesn't the potential difference in charge just flow directly through the commutator instead of the wire, since the commutator is conductive? I've been wondering about this for a while now, and haven't found any explanation as of yet.

Thanks a lot for explaining this detail help a lot But I have doubt how to connect coil to cometator if possible pls help me

[@MasterFeiFongWong]

Electric Generator Design that's powered by it's self once it gets going & perpetuates more electrical current then is needed for it to run continuously on it's own. Step 1: Calculate how much energy you need pumped into an electric motor to make a vertically positioned circular platter with magnets in-bedded horizontally around it's left side and right side (so there pushing force is pushing out sideways relative to the vertically spinning disc) to spin as fast as you need it to. Also better to make sure these magnets are shielded around their sides & back with metal that has high permeability so the magnetic field they are emitting is focused fully out sideways. :D Step 2: Calculate how many sets of copper coils you need to be interacting with magnetic fields to achieve this & to perpetuate more electrical current flow then is needed. :D Step 3: Build a round horizontally positioned platter covered in all these copper coils pointed down that does not move (Is stationary) :D Step 4: Build a round platter covered in powerful magnets pointed up that can spin and place it directly under platter with hanging copper coils. :D Step 5: Position the vertical platter that is motorized close to the horizontally positioned platter covered in magnets pointing up so that when the vertically positioned platter spins the in-bedded horizontally positioned magnetic fields slam sideways against the edge of the horizontally positioned platter causing it to spin. :) Step 6: Make sure enough of the copper coils are feeding their electrical current into the electric motor and the rest of the copper coils are linked into a set of rechargeable Battery's placed in the closest most convenient spot. Step 7: Build a duplicate setup of horizontally positioned discs with hanging copper coils and disc with upwards facing magnets and assuming the first set of discs are positioned to the front left side of vertical spinning disc, position the other duplicate structures to the front right, the back left and the back right of the vertically positioned motorized disc. As the vertically positioned motorized disc spins the horizontally in-beaded magnets will now hit into all 4 horizontally positioned discs causing them to spin. so you will effectively be using the spin of one disc powered by one electric motor to spin 4 constructs that are each generating electrical current. now build this whole setup multiple times over and use the current perpetuated by it to power up scaled electromagnetic generators that are equal to or more powerful than the ones used in a nuclear power plant. You will now have a device that is self perpetuating off of it's own electrical current perpetuation and no nuclear waist to worry about. Here is the reason why my device does work. You see even tho the more electrical load you impose on a system ends you up with greater back emf hindering your devices ability to move and generate current, there is a way to work around this. My device multiplies the amount of mechanical motion that is taking place because of the 1 motor. On top of that, it eliminates any extra resistance that could have been imposed on the motor by making the other wheels spin by having the magnetic fields hit the rotating discs the way I described. You see, the vertically positioned disc connected to the motor is perpetuating the spinning of at least 4 main discs that are spinning magnets at no extra effort on it's own part because as it spins around powered by the motor, it is the horizontally positioned magnets that are shielded by high permeability metal that are using their magnetic push out sideways to force the other horizontally positioned discs to spin. So even tho each of those 4 discs spinning are somewhat hindered by the back emf it does not change the inescapable fact that each disc is perpetuating the flow of current in the copper coils above them and the amount of electrical current being perpetuated between all 4 discs is greater then the amount of electrical current the motor needs to run at max potential. It is called over unity and the extra electrical current the motor does not need can be fed into larger more elaborate electric generators. Imagine 12 of these designs contributing to the power needs of a much more powerful design (Probably electromagnetic) that is utilizing this same idea of multiplying the number of horizontally positioned discs that spin because of the motion of one powerful motor spinning a vertically positioned disc cleverly positioned so that it spins at least 4 other discs at a much higher velocity because of it's more powerful design. In short its all about multiplying what the first motors disc is interacting with & second, up scaling the design to more powerful designs that utilize the same principles.

How many turns in the coils?

[@alchemy1]

The brush connection and the commutator explanation needs vivid detailed explanation. Otherwise you would have said it would be discussed more some other time. But I don't think that was your plan. I am doing this for those who really want to know but don't want to bother people and are too shy or lack self confidence and or concerned that if you explained it more you might still not be clear so they eat it up and suffer. This is how the details of what vivid explanation should cover. Show the exact path/wire of current with care and clarity not with word slur and haste. From where it is coming and show the exact brush that it enters into and what commutator, then show the path to the rotor coil and how the rotor turns as it experiences the magnetic force and the path of the current going in the coil and the path of it heading out and how by then the rotor has turned ( how? sheer momentum) and as the current heading out, what commutator and brush it exist from.. That is the crux, the very core of this video. If anyone don't get that right the whole teaching got wasted which is typical. Further explain the reasoning for why the so called pioneers had to come up with that transition device the commutator and the brushes although it doesn't look like a brush ( we know what brush looks like). It looks like a strip of metal obviously. I know why you didn't explain it and it shows later as your absent minded attempt to operated it using AC supply and worse yet calling it synchronous motor another equally fancy name for another fancy name induction motor with brushed all twisted in wrong phrasing no matter what terms you would have used. I needed to see closer shots of your commutator, most likely if you left the brushes alone and supplied lower voltage and not 120, you could have got it going with a little starting effort with your hand and then you would have had to turn it off sooner than later so it won't get too hot. You never explained the difference between commutator and slip ring. They are two different term for two completely different concepts. I myself was a pain in everybody's in the classroom and you can see why and you can also see that there is nothing anyone could do about it because I alone was right by every standard with my questions. When you brought up the Eddy current you immediately said that it is for another subject so you didn't leave people empty handed wondering what is that. By the way there is a reason why your attempt to use AC to turn the motor failed. It is because you don't know your stuff. If you did you would have known it already that it wouldn't work. Students don't know so you get away with it by moving on. There is only two types of teachers that tolerated me. The one that knew their shit and the true humble one. Typically one or two teacher in the entire school but mostly maybe one teacher if I got lucky.

[@PhysicsHigh]

[@Mega6501]

I still didn’t get the difference between commutator and slip ring by just moving the brushes?

[@PhysicsHigh]

When the brushes are at the extreme (slip ring) the current always enters one side of the coil irrespective of its position. This results in AC When brushes are in the middle, due to the design, the current now switches every 180 degrees to ensure current goes into coil so the the direction is the same way relative to the static. This results in DC.

At time frame 4:10 he says that now he is going to supply power to the device and then immediately, At time frame of 4:12 to 4:14 what does he exactly say? Can someone put in quotes exactly word by word what he says in that two seconds.

[@secondthoughts-3417]

"-and it's now going to act like a motor"

[@MusaMusa-sw4ek]

People get confused when you just say flux changing, you can't just change magnetic flux and expect to get current on the output terminals of the coil ,but the rule is magnetic flux must cut perpendicular in the wires or any conductor, in order to induce electricity .so man correct this word of magnetic flux changing to magnetic flux cutting OK!

[@surajpharande8432]

At last two years ago when I was applied for electric motor generator hybrid machine (Electric motogen I.e. Generation of motive power and electricity together) but in first examination report because of technical defects in claims (obviousness) is not patentable but novelty and industrial applicability of invention is written. If I get any required technical support for invention then it makes possible as patent. If yours or relative well known person will intrested with it then I will provide necessary information. After first examination report when I prepare for submission again about two months peoples admit in goveroment hospital by kidnapping. Then I keep this work aside, days are passed I fail to submit at respective time report. It may be because of I am not son of western European christians so I don't have right to patent. But it is very necessary to spread my concept with you. Thanks.....
