Twin Rotor Bedini DC Motor

[crisisofconsciousnes]

so does this bedini motor create current or just alter the voltage?

[drijfkip1]

"...done some load tests with this motor and found current draw decreases under load..."

As a good scientist you should first think of measuring errors don't you think?

Did you use a True RMS power meter? Because digital multimeters are useless in this situation.

Actually, digital mutimeters are the only reason why people think those bedinini spinning things are something special...

[swallin19]

@drijfkip1 It beggars belief that people fail to understand measuring AC power in watts so easily, it only works with meters and DC, and power meters are designed for sine waves, not the choppy back EMF ridden output of these devices. Try feeding the power to a lab heat sink and measuring the heat increase and do the physics to calculate the power.

[truvak]

please!!!! a DYI! thanks.

[ZPDM123]

Ah one more thing, if you flip the electromagnet vertical, you could put in as many coils as you want around the two (vertically spaced) rotors. I suspect that has occured to you.

[ZPDM123]

Can't thank you enough, was thinking along the same lines. Have you tried a C shaped core? On a horizontal rotor, North and South facing vertically? Should see the same effect I would think, though perhaps other things as the magnetic flux would be closer to a closed loop. Thx again.

[jonnydavro]

Hi ZPDM123.Thanks for your interest and suggestions.A U shaped core would be an interesting experiment,maybe a flyback core but you can get multiple rotors spinning of a standard bifilar coil like in this vid you just have to use the right type of rotor which is a single diametric magnet.Have a look at my one magnet no bearing bedini coil orientation test as it looks like you can spin a magnet in any position in relation to the coil.Thanks for your comment.Jonny

Hi, so the red lead from the meter gos to positive on the battery what about the black lead. Im still confused

[jonnydavro]

@333kgb.The black lead goes to the circuit wire you would normally connect to your battery positive so the current flows through the meter before it enters your circuit.Jonny

[333kgb]

@jonnydavro Thanks for the info. So how is ur motor doing are u getting more Mamps out than put in. I know the secret to get overunity with the bedini. I would have told u but I dont know ur email.

[jonnydavro]

@333kgb Hi.You have to be careful when measuring the output of motors.You need to measure the output power in watts and compare it to input power in watts.It is quite easy to get a higher mA output than input but the voltage will be lower so its best to measure in watts.Did you manage to hook your ampmeter up ok?I would like to know what you think is the secret to ou with these motors.Send me it in a pm or i can give you my email no probs.Happy experimenting.Jonny

[333kgb]

hi, nice work! I have a meter and I want to know how much amps are coming out of the battery were do the 2 leads of the meter go

[jonnydavro]

@333kgb.Hi.Set your meter to Ma and put the red lead on the battery positive and connect the black meter lead to the positive input lead of your circuit so it is essentially in series with your circuit..Jonny

[KippTheKidd]

Will this run for more than a month without needing an external power source?

[333kgb]

The negative on the primary battery go’s to the inner 20 gauge wire on the coil which also go’s to the emitter on the transistor and the inner 24 gauge wire from the coil go’s to the collator on the transistor then the neon bulb is connected to the emitter and collator does it matter which way I put the neon bulb? And is there any problems you see in this hookup? Thanks for you help!

[333kgb]

The potentiometer is connected to a 24 gauge outside coil wire. My 1N4007 diode is connected to the positive on the secondary battery. Then the outside 20 gauge wire runs to negative on the secondary battery and on the positive on the primary battery

[333kgb]

Hi I have been trying to get the bedini motor to work, but the wheel just comes to a stop. My setup is 1N4001 diode is connected on the emitter to the base on the transistor. Then the base is connected to a 470 resister. Then resister is connected to the potentiometer.

[TheKaos90]

Your idea is good ... i mean , the energy on the other side of the coil is almost never used , now you just made evetything more efficient

[jonnydavro]

Thanks TheKaos90.Each end of a coil is an electromagnet so it makes sence to use both poles and get more work from a coil for the same input.I took this idea a bit further with my 4 rotor bedini,have a look if you get a chance.Jonny.

[TheKaos90]

@jonnydavro I had the idea (and yeah,still have it :)) ) to make a motor out of 1 coil to move the rotor wich is the motor's hull

[RadicalRC]

What about the motor I see when you flip over the right hand CD drive unit. I see it's connected to 2 wires bolted into the lower left terminal block. Makes no sense.

[jonnydavro]

Hi Dave.This motor is a DC/Bedini hybrid.The "more information" to the right of the vid and circuit diagram explain everything.Jonny

[ParaglidingManiac]

Are those magnets on a disk? In what patern?

[jonnydavro]

Hi.There are 4 magnets on each disk.On one the north poles face out and the other,the south poles face out.Jonny.

[chucknorris0325]

if you spin those suckers fast enough theyll explode!! can your motor do that?? haha

[larryllix]

The only loses are mostly dues to the heat in the coils and pulsing circuits.

Even 50 rotors only have 50 times the air resistance and bearing resistance. Those factors are very slight due to the dsign of the smooth rotor and efficient bearings.

[jonnydavro]

Hi pkrska.One rotor has North facing magnets and the other south facing.The coil has a north and south pole so the north rotor faces the north on the coil and the south rotor faces the south pole on the coil.Hope this helps.Regards jonny.

[pkrska]

Do you have N or S pole facing the coil?

[TARSEMSINGH1000]

this is important for you

[PhotonDrive]

No torque - the problem with ALL pulsed-coil arrangements: even worse for all mag-to-mag only - "perpetual" devices. Now that magnetic generators are beginning to propel magnetic-drive vehicles, all new research is focusing on this new fuel-less/battery-less powering of self=propelled transport - some of which uses multiple mag-wheels (these are rapidly disappearing from the net so you will have to do some searching and inductive thinking)!

[pkim0526]

Can you tell me what was the total input power and output power in Watts? I want to know the efficiency.

Thanks

[dyldyljkj19]

How long will this run for? Can you attach anything external to keep it running? I'm into robotics :^)

[dllabarre]

Nice... funny though - just the othr day I was trying to figure out a way to use both ends of a coil with a set or North and a set of South magnets. Thank you for showing me 1 way to do this.

[jonnydavro]

No problem.If you are interested in using both poles of a coil,have a look at some of my other vids,you may get some ideas from them.Good luck regards jonny

[MegaJATINDER]

hello ther my name jatinder i love u

[jonnydavro]

SWEET!

[MrWombatPPC]

I was realy hoping to see the CDs keep on spining when the guys removed the battery connection !! :-)

[PSPTUBE256]

It looks like a PlayStation 1 disc motor.

[jonnydavro]

Hi PSPTUBE.The motors are from portable cd players.Regards jonnydavro.

[chazdaspazman]

nice job =)

[BeginnerThought]

Hello,

I am VERY new to this but have a few questions about the coil and 2nd wheel.

1. When the coil fires, does it produce the opposite polar reaction on each end of the coil?

2. What is the polar arrangement of your magnets(all N facing out, etc.)?

3. Does the second rotor have the opposite arrangement of magnets than the first?

4. And lastly, what are the wire gauges and number of wraps you prefer for your coil?

Thank you very much for your time,

Beginner

[jonnydavro]

Hi Beginner,In answer to your questions.The coil has a north and south pole.One rotor has north facing magnets and the 2nd has south facing.The coil is wound bifilar using two 250 gram rolls off 26swg enamelled copper wire. Each roll was 170 meters long and i just wound all off it onto a third empty spool at the same time.Hope this helps,if you need any more info,let me know.

regards jonnydavro

[fdoca]

jonnydavro , You and thedaftman are the two has multi motors running at the same time as I found on youtube,

Wondeful job, I would start to getting parts together and try to replicate this, Can you help? I'll be really appreciated .

[jonnydavro]

Hi fdoca.I suggest that you build a simple Bedini motor first and learn how to tune it for low current draw,high rpm,get to know the motor and then move onto the twin rotor/4rotor motor.This way you will be able to solve any problems that you may have and you will have a lot off fun on the way.I will help all i can. Regards jonnydavro

[LinkBlink]

What if you placed 3 disks & 3 coils in a triangle.

[jonnydavro]

Hi LinkBlink.Have a look at some off my other video's. One off them is a 4 rotor Bedini motor with 4 coils.If you use 3 coils or any odd number there will be a conflict with one rotor having a north and a south pole acting on it so i think its best to use an even number off coils/rotors. Thanks for your interest and comment. regards jonnydavro

[bluanvil1]

Hello Jonny

I am a complete novice here so could you give it to me in a nutshell? Whats going on here? I have an idea of a magnetic pulse motor running a flywheel to then run a generator. Is this close to what you have here? Sort of an overunity device? Thank you for your time and that is a nice clean demonstration you have here. Hope to see more.

Best regards Mark

[jonnydavro]

Hi Mark,Thanks for your interest and kind comment.What I am basically trying to show here is that by utilising both poles off a coil you can get twice the mechanical output for the same current draw for 1 rotor and by combining a bedini motor with a dc motor and feeding the output back in you can get high rpm motor with low power consumption.See the more information for more details.Hope this helps and thanks for your interest. Regards jonnydavro

[bluanvil1]

Thanx Jonny But there is on thing that I have to know. When you run them and stop them do they always sync up like they did when they came to a stop? Or were you just showin off for the fan's?? Thanx again for the help. Keep up the good work. Best regards Mark

[jonnydavro]

Hi Mark,This Dc hybrid Bedini motor syncs very easily and worked first time straight out off the box.The Secret is to make the magnet placement on the rotors identical so both rotors are triggering the coil at the same time.Out off all the motors i have built so far,this is one off my favorites.Hope you liked it and it has given you some ideas. regards jonnydavro.

[pirondinimarco]

It is wonderful.

[TodMcInerney]

Very interesting, you say they are drawing 18 milli amps. Do they have a power output as well ie: are you recharging the battery?

[jonnydavro]

Hi TodMcInerney.They do have a power output but i am using it to partly run the motor,it can recharge a 2nd battery but at the cost off increased current draw.Have a look at the schematic at the start off the video and you will see what ive done.One other thing ,this motor will spin in sync quite quickly at 7mA.

Thanks for your interest. Regards jonnydavro

[kevininbc]

Nice work! A pair of those would make a nice skateboard!

[Darkbain]

Looks like the first rotor also picked up more speed after the sync.

[jonnydavro]

Hi Darkbain,The 1st rotor does speed up after the sync along with the 2nd rotor as both rotors are triggering the coil at the same time so they arn't fighting each other.Thanks for your interest.Regards Jonnydavro
