Nope, a railgun works on a different principle. In short you have 2 parallel conductors (rails) and a conductive projectile. The projectile touches both rails and carries a current which produces a magnetic field in both the projectile and the rails. Those magnetic fields opose each other in a way that that the projectile gets shot parallel to the conductors.
I am just amazed that this works as well as it does. I saw coils made for maglev trains. The coils were busbar copper material. The thickness was just fat metal material connected together. They also use aluminum bus bar as the cost is cheaper and you can go roughly twice as far per pound. That is what the working med said. Job well done Daniels Electronics Lab.
It's basically how recent maglev bullet train works, especially with the superconducting traction coils, in order to move them up to high speed. They're crazy fast for a train.
If you staged 3 phase like this inline itd give you rotation but youd still get it to drive out. Much like a rifled barrel if you got your diameter close it'd be more effiecent too
Thanks, so the motor spin-up sound is your single phase to 3-phase converter? I suppose the speed controller was for the single phase drive motor, where then you took the 3-phase from the other side for the linear motor?

Linear motors are very much a thing. This particular one is a good demonstration of a linear induction motor. It runs off three phase power. A 3 phase rotary motor has a rotating magnetic field set up while a linear induction motor has a magnetic field that moves in the linear direction. Just like a rotary machine a LIM also has terms associated with it such as slip, synchronous velocity, slip velocity etc. Instead of rpms its in m/s. The main difference from a solenoid is that a solenoid just has a stationary field that is set up and the coils usually enclose the magnetic element/plunger.
@shakeb raza probably about the same cost. Rather than rotate a shaft powering belts, you're directly moving a ferrous material linearly. This method might be cheaper in the long run but depends on how often this method could become damaged due to pieces of metal sliding over the top of it
Hello we are making the LIM but its length is 42 Cm. we are planning to rotate the Stator (Containing slots) in stead of alumunium! Can the slots be able to displace it self????
There are certainly motors where the coil side move themselves instead of moving the aluminum side. Essentially the two types are called long primary short secondary, and long secondary short primary. All electromagnetic induction trains would be long secondary short primary because the primary is much more expensive. If you can send me more information about your project I might be able to better advise you.
Not 100%. Linear motor is the propulsion part of the train ... Not strictly the «levitation ». In maglev train levitation is done via similar process, but not strictly the part shown here. For levitation, you need to turn the coils 90° up ...
@@Wingnut353 thats a good point, I was thinking it wouldn’t have the same mechanical advantage but it could have a speed and or precision advantage, its worth thinking about. Like I guess you get a rotational energy that can add up when you use a motor with like a belt but Im thinking of like a linear bearing that is actuated magnetically so not a ton of force, I don’t know if a rotating magnetic field actually increases the torque in a way that a linear moving field couldnt. I just don’t know enough to say one way or the other but I can see it being really useful and cuts down on components and cost as well
Thank You. Nice demo. Is the voltage DC or A/C. As I dont know what VFD is. Also could you use a copper plate instead of aluminium? Would you get more lift with a lot more turns of wire? Apologies for so many questions. Thanks
Since it is using a VFD it is going to be AC. The VFD essentially takes the 1 phase power from mains, rectifies it to DC, and then uses IGBTs to create a 3-phase AC current (along with being able to control the frequency too). VFD = Variable Frequency Drive.
Wikipedia magnetism, induction coil ... Lower coil produces a magnetic field every where. That MF produces a circular current ln the alu plate. That inducted current tries to produce an other magnetic field that fights the first one. Magnetic fields from lower coil fights the MF from top plate resulting in a force that pushes the plate ... The same as any motor. But in flat configuration.
