you just need the battery to kick start the motor or provide the kinetic force it needs when you push it. Run it to a generator and controller to run an off grid or on grid
I once built the same, but with three magnets, for stabilization and frequency. For two magnets, use two coils in parallel or in series at the same time. 🖐️🐬😉😂🍀
I wood like to know what the pulling force the magnet has. I am trying to use a reed switch in an engine powered by batteries and want to be able to turn off the switch with a magnet as i have switches that are normally on and need to turn them off. Thanks...
i think i heard ur dryer in the background.. it would go good with the 9 hours of washing machine sounds i found on here... seriously 9!! hours look it up grt job
Hello , which it is the last element that mostras in your video, and that is the type of relay you're using , and where it connects to charge a battery . thank you
can i pass one inductor in parellel to reed switch with diffrent supply.. Thanks, also what is its switching speed, i want to use it in oscillator circuit
What is the role of this diode ? If the input voltage is Dc why you must use a diode ? With dc input the relay gives constantly north and south electro magnetic pole
Salut am si eu citeva intrebar daca se poate in legatura cu reed motor. Daca pui magneti mai mari poate functiona? Poate scoate si curent sa incarce o baterie de 12v? multumesc mult
Where should be the reed switch be? Next to solenoid, or at 90 deg counterclockwise position to create maximum pull on the rotor magnets? I guess it is the rotor magnets which control the reed switch.
Great job very tidy, never seen that kind of reed switch before, I was wondering what it was out of :) it looks like a magnetic head out of an old VCR, I have a couple of coils the same as yours out of an old TV set but the reed switch has me stumpt.I have been using the ones on ebay from China and an LED diode for the arking works well.
Hello again; would like to know what amperage the reed switch could handle and where to find heavy amp reed switches for my heavy flywheel pulse motor project. My power supply tells me that my circuit draws an amp and more as I raise the voltage. I should use a coil with higher number of windings and thus draw less current? Please reply cause I actually cooked my reed switch a couple of times.
Connect the reed switch to open the gate of a MOSFET or other transistor, then your reed switch only needs low voltage. Even could go far as connecting a reed switch to arduino (or other microcontroller) and a motor driver for real time speed control.
What kind of “magical” sourse of power do you use? You didn’t even mention it while it’s the biggest problem with reed switches, they burn really quick.
What kind of reed switches are you using ? The reeds don't fatigue , the contacts are in a inert atmosphere the life is in the billions of cycles , one billion cycles with two poles at 3000 RPM would be 19 years continuous , a reed switch rated for 10 billion would last almost 200 years .

It stops the back emf from the coil arcing across the reed switch contacts, When the coil is turned off and the magnetic field around the coil collapses, it generates a high voltage spike, this can arc across the contact or damage other stuff connected to the circuit. At least that's why I put it there.
The diodes are connected in inverted parallel with the coils of relays, solenoids or stepper motors to protect the drive components such as, for example, transistors or SCRs. This is because, when the inductive load (motor, relay, etc.) is turned off, the magnetic field created contracts and generates a high reverse voltage which can burn the drive transistor or SCR. With the diode, it does not lead with chain drive, but puts on short induced at shutdown, thus protecting the transistor or SCR current. See the link below for an example circuit with diode.
I get t it. The field collapse can ruin the motor. Blar blar blar check out lidmotor on RU-vid. You will see what I mean. His recent video shows it without the diode working fine. I've built tons I mean tons of these reed switch motors. Check it out.
Ary Junior yes the diode protects the reed switch from back emf currents that could trigger sparks and damage the reed contacts..you can also place a capacitor there where the diode is..that will also absorb the arcing that occurs between the reed contacts when they switch on and off continuously!
Digi-key has reed switches rated to 3 amps at 100Hz and there is no reason you can't put multiple switches in parallel for higher amperage , but it would be hard to go over 3000 RPM . still that covers 80% of the motors I own.
Cristiano isso e um cabeçote de um vídeo cassete velho, e se não me engano dentro desse coisa preto ai é um reed switch , só não sei se é um NA ou um NF, pois pelo vídeo ele serve de chave abrindo e fechando a alimentação da bobina que se opõe ao imã pregado no cilindro de cabeçote de vídeo cassete, esses imãs voce encontra no mercado livre.
yes it has a ready made coil and iron in between, cheap electromagnet available rather than winding ourself..that's all nothing else is used in the relay
+Darryl Edington No, you said "free means humans don't pay for it" and that is an open ended statement. and FYI our Sun is a star. Just like the Suns of planets in other solar systems are stars.
+Darryl Edington "JUST LIKE IT TAKES MONEY TO COLLECT AND DISTRIBUTE ALL ENERGY. Any questions?" Yes. if it cost money to collect and distribute all energy, then oil is just as free as solar. We didn't pay for the oil we paid to have it found, pumped up, refined and distributed. They will do the same with solar, charge us for collecting it, storing it, converting it to AC and distributing it to our homes.. So all we will be doing is switching from one power company screwing us to another power company screwing us..
+Genma Saotome Each time you disconnect the coil it "kicks back" and can generate a high voltage in the opposite direction. The diode shorts this to protect the switch from arcing.
Motors are basically large windings of coils, and a coil is basically an inductor. The thing about inductors is they like to store a portion of their electrical charge in the form of a magnetic field around themselves. In motors, this storage of energy is what enables them to move. The magnetic field attracts to an opposing pole, and then it is switched off, the other coil generates a magnetic field, and it is attracted to another opposite pole. The problem with inductors and coils is this stored up energy has to go somewhere. This particular motor uses a reed switch to quickly open and close the circuit giving the motor power. When the power is rapidly oscillated like that, the coils will have to dump their stored up energy somewhere. Since it can't send it through the rest of the circuit (because it's been opened), the current builds up at the switch, and when it is closed again releases all of that current and then some, more than likely in the opposing direction of the normal supply current, which is dangerous. Think of it like putting a kink in a hose, then opening the faucet even more and unkinking the line. Much, much more water will come out the end and at much higher force for a second or two before going back to normal. This is bad. In this design, the diode used is known as a flyback diode, and any diode can work in this configuration. It goes by other names, but the basic principle is that it directs that buildup of current away from the switch and only enables it to flow the way it's supposed to. This can be used with a pull up/pull down resistor to make sure the stored up, unused current is given a safe path to ground with the cycles of the reed switch. As for what a reed switch is, it's like your every day switch that either opens and prevents the flow of electricity, or closes and allows it to move. Reed switches are different than regular switches because they use magnetic fields to close or open. That's what those magnets are for that he puts on the motor. When one magnet passes by the switch, it closes and then by the time it's gone, it opens and power is cut to the motor until the next magnet passes by. It uses the natural momentum of the motor to give it most of its speed. Kinda like going down a hill on a bicycle. There's no need to keep pedaling when you can just let gravity do the work for you.This means the motor is only actively drawing current for milliseconds at a time, versus constantly sucking current from the supply. And it can still attain the same speeds as pumping it full of power constantly. The benefit of this is you can theoretically run the motor at a much lower voltage but end up with usable speeds. A much more common and practical approach is to give the motor a PWM signal. PWM is Pulse Width Modulation, and think of that like the digital version of what's been done here with the reed switch. Let's say you have a motor that runs at full speed on 12v. By PWMing that 12v line with the appropriate oscillation, you could run the motor at 12v speeds on say, 6v. This is relatively normal, and is how most motors in every day use function, especially RC toys. If they didn't, then the batteries would die much much faster. EDIT Actually, on further inspection it looks like this motor is relying purely on magnetic force to move. The power lines hooked up to the terminal blocks feed power to that little orange box, and the black thing is the actual reed switch. And the power lines are wired with the reed switch so it opens and closes power to the orange box. The orange box is a coil most likely, so the reed switch closes when one of those magnets gets close, which therefore turns that coil into a small electromagnet which forces the magnet away from the coil, turning the motor. Then the field quickly dissipates and re-energizes when the next magnet passes by. That's fucking genius.
+Javier D.F. (DF) Put the reed switch on the other side of the coil and spin the motor in the other direction. You should also be able to put the reed switch on the opposite side of the rotor, across from the coil, and then the direction would be set by the direction you spin it on startup..
it looks like an NO reedswitch to me..as the magnet approaches the relay coil, the reed switch senses it and closes the circuit and the coil becomes a magnet..the electromagnetic field is induced and it repels the N faced magnet on the rotor, as it repels, the rotor magnet leaves the reed switch and the electromagnet dies down..this happens repeatedly inducing motion of the rotor..
Grant Anderson if we placed a large heavy spin flywheel it might also spool up an alternator fixed along its axis..lidmotor made some experiments and it showed that reed switch pulse motors tend to draw less current as loads are placed on them unlike conventional dc motors which start burning up more current as you load them
+Baymax I really like this clean, simple implementation. I purchased a number of reed switches, which are closed and pass current when in a magnetic field and I'd like to make a motor with one. It looks like the fellow in the video actually used a small magnetically-triggered switching relay, but it's electronically similar to a reed switch. I need to figure the positioning of the inductor that moves the magnets on the wheel relative to the reed switch. And how to wind the inductor - I imagine you want an iron or ferrite core in it.
MUY BUENOS Y BONITOS PROYECTOS, PERO ESTAN COMPARTIDOS POR UN PROFESOR SORDO MUDO Y EGOISTA. LO LOGICO ES HABLAR Y MOSTRAR UN PLANO PICTORICO DEL PROYECTO, CON DETALLES DE LAS PIEZAS UTILIZADAS.
pulse motors are not fake, I have been building all these so called free energy devices, none of them work, they are great for learning how to manipulate electricity and multiply power, but they aren't running themselves. I'm building a pulse motor, I will be able to run my old laptop off grid and run lights. Trolls be trolling.
