If you cannot describe the physical details of a circuit, you should go back and learn what's necessary so that you understand it. In your case, it's 100% clear that you fully know the operation because your explanation is clear, accurate and correct. I taught STEM topics at UC Santa Cruz for five years and I discovered the following: 1) when a topic is new to students, like all new knowledge, it requires effort to learn. Even if you explain it correctly, it takes effort to acquire the knowledge because it is new. 2) if the experienced person decides "I'm not going to tell them everything they need to know - that will motivate them to work harder to understand! Besides, nobody helped me!" A large percentage of yt videos use method (2). In some cases, it's because they do not understand what they have so they cannot explain it. If you really want people to understand what you're trying to convey, the method you used to explain the Bedini motor is a model because holding back details does not motivate students. They are already facing the challenge of understanding something brand new to them. I congratulate your effort, very good job. Nice build on the motor, too - thank you.
Me parece fantástico haberte descubierto, y a demás ahora en ingles!! Gracias, aprecio mucho todo tu trabajo. Muchas gracias. Tus videos son oro puro. Realy.🤩
7:20 your description is wrong, it should turn transistor on then while the magnet not cross the coil the transistor is turn off, repeat on off make it rotate
@@ludicscience So this is a more direct way of describing the operation of sensorless BLDC drivers. In other words, the ones that don't use hall sensors? Instead of saying such terms as back EMF. The only difference is, the sensorless bldc driver does start without help. So I would think that the magnet's back emf ( sending current) is used to show its location. In other words, it is doing what this experiment is doing, triggering the base/gate of some a transistor/mosfet or what have you. When I use one of them drivers to run my make shift bldc motor, I typically need to give it a helping hand except once in a while. I guess it depends on its mood, temperature, humadity or what have you. Plus the motor is not exactly machine made to precision with an uneven airgap etc. And once in a while when it is just at the right spot, it runs like grape ape with only 5 V. Too fast for my comfort so I actually have to lower the voltage. And sometimes I have to really give it a helping hand and it still fights.
You can also use a 10mm or 20mm Neo sphere magnet and get a really high RPM!!! One of my favorite projects. The bigger the magnet, the easier it is to spin it with your hand.

The effect of the thin wire is to produce enough emf from the induced current to trigger the transistor. The thick wire won't be efficient because of its higher resistance.
The coil creates AC at the base. You need to let the negative part of the cycle flow as well or you will get voltage spikes that destroy the transistor.
Nice video and good explanation. Bedini motors are good starting points for beginners. And you can extend them to create a mechanically switched boost converter using the flyback spike from the drive coil. It's a good way to teach students the difference between voltage and energy. Instead of a bifilar coil, you can experiment with a separate fine-wire coil placed in the center the drive coil. Lots of fun projects here.
Is this what I have in my ebike? I have a brushless hub motor that needs momentum in order to start. I think it is a sensorless controller I'm using. Thanks for the video :)
it is a transformer but with a diode so it just take the inductive current by the movement of the magnet and that current switch the transistor to feed the other coil that turn the magnet.
Hello Ludic How many turns for the 2 wires? And can I use a BU406 npn Mosfet? Thank You my Main Teacher and helping hand ( I look in you"re vid's for an item I'm working or playing with and see the right way,You're an inspiration Amigo, Bye from Holland Antony
I like your setup. Recently I tried the circuit aswel. It looks like the transistor doesnt shut. There is a circuit on the thick wire. Resulting in a north pole magnetism in the spool. Do you have any idea?
What would be the point of that? If you have a coil anyway just use it to create the magnetic field. Electro magnets can create much higher field strengths than any permanent magnet.
It needs to be a good electrical conductor and not contain iron. I'd rule out steel wire. Good options are silver, gold, copper and aluminium. It needs to have an insulating coating (usually varnish) so that adjacent turns don't short circuit.
I don't like the name "Bedini motor": Bedini is nobody, he didn't invented anything. This is a simple ancient pulsed-inertial motor, by an electronic commutator. Who is Mr Bedini??? Nobody.
You cant use bare copper wire, it has to be insulated wire ( some call it magnet wire), motor winding wire is insulated although it looks like bare wire!!!
Hi there! I really like this simple version as yours, much easier to understand. I'll try it on my linear style motor soon! Greetings from Hungary! BLADE
Hey, came across this video today. You explained that in really nice way. Could you please make a similar video explaining how to make and how it works for the Single battery operated badini magnetic charger
Yeah! Bedini "motor". I built 4 of them. About 10 years ago. BTW, you can use it to charge a big battery while depleting a smaller one (the run bat). Is it "Over-Unity"? Is this a big bat. really conventionally 'charged'. I will not discuss these kinda controversial considerations. Guess what? With the DadHav very clever circuit you do not need a 'trigger coil. One coil is enough to run a pulse motor. You also do not need any reed relay, any mechanical switch or whatever. The few experimenters interested in this kinda stuff can consult : "1 Coil Brushless Motor Driver (Multi-Phase)". (DadHav) ua-cam.com/video/8b4xlCKn3LQ/v-deo.html This circuit can be simplified (cut in half) but is very tricky to get it run.

I wonder what effects on heath or body or psyche would be, to be close to a fast rotating magnetic field, with some improvements to build you can rotate a magnetic ball or wheel quite fast, i have built design and made it "better" I will sit by it while it runs, i have some copper rings that will vibrate when it gets close in the field range of device, Ive yet to know if it improves or not my well being but not much out there on the study of magnetism effects on the body for healing but hey just being weird on UA-cam and throwing it out there.
0:16 : you say wrong when you say "no commutator": there is a commutator: the transistor. It's an electronic not mechanical commutation, it's a simple and not double commutation: only off/on and not inversion of electrical polarities, but it's a commutation at all. Only homopolar motor has the privilege of not having any commutation.
This build has many problems. Wrong coil geometry, wrong magnets, no core material. Output energy is totally wasted, which defeats the purpose of this device. This device has very little in common with a proper built bedini ssg.
I love the way you explain everything in such detail it really helps us self-educators out here in the world
The Bedini circuit also provides back emf pulse of negative charge that can be dumped in a capacitor bank and fed back into the loop.

So the magnet passing the coil acts as generator turns the transistor on, sending current to the base of the npn
Yes

Can you also use a BD139 for this circuit?
Yes you can.

What voltage is the motor running at ?

Can this motor use a starter capacitor to kick the rotor into operation without help when you apply power?
No
What if you replace the resistor with adjusting resistor. So then with motor running, you can adjust best position for rpm.
It's a 1:1 ratio coil winding.
The effect of the thin wire is to produce enough emf from the induced current to trigger the transistor. The thick wire won't be efficient because of its higher resistance.
What is function of the magnet? Is it switching core for the coil? Thanks
Could it become self start by adding a 1m ohm resistor from vcc to base?
No
What for is the diode in the scheme?
The coil creates AC at the base. You need to let the negative part of the cycle flow as well or you will get voltage spikes that destroy the transistor.
@@superdau This type of solid-state driven motorization circuit can operate without a 'clamping' diode'.
Remember those Cosmotron's from the 1980's?
@@chadcastagana9181
If you want to fry your transistor, leave the diode out.
Very nice friend. But Why diode is used?????

Did you really fall for this hit piece? 😂 Flyback spiking
There is no protection in the event of a short circuit between the windings.
What is the practical use of this product?
So id I spun the rotor with a propeller in the wind, could I charge the battery?
Is this what I have in my ebike? I have a brushless hub motor that needs momentum in order to start. I think it is a sensorless controller I'm using. Thanks for the video :)

Can you make a simple Bedini battery charger ? BSG.
There are much more efficient ways of xharging batteries

I like your setup.
Recently I tried the circuit aswel. It looks like the transistor doesnt shut. There is a circuit on the thick wire. Resulting in a north pole magnetism in the spool.
Do you have any idea?
That is not Bedini’s motor, as Bedini’s SSG collects transient spikes of collapsing magnetic field. All you have there is a unipolar motor.
Can neodynium magnet be made more powerful by wrapping copper coil around it and powering the coil with variable volt or corrent or both.
Yes. However, The wire will repel itself from the magnet if you do that. You'll need to fix the wire to the magnet
What would be the point of that? If you have a coil anyway just use it to create the magnetic field. Electro magnets can create much higher field strengths than any permanent magnet.
Nice job !
Is there any substance other than copper which can be used to create electromagnet.
any conductor?
You can use bananas. Lots of them. Of course your power requirements will be different but that is another problem.
It needs to be a good electrical conductor and not contain iron. I'd rule out steel wire. Good options are silver, gold, copper and aluminium. It needs to have an insulating coating (usually varnish) so that adjacent turns don't short circuit.
