Awesome! I will definitly try to build it myself! Always wanted to build a small pressure pump. A linear motor would be much more easy than translating a rotation to a linear motion afterwards. I am so happy I found that right now :D
Having identical magnets at both ends could make for a better demonstration, and using this to drive a bass speaker would be a great video, especially since a version of this concept is used in a subwoofer that's much more efficient and powerful than traditional drivers by keeping the coil stationary and making the magnets move, the amazing Powersoft M-force.
A spring can also be used to push the piston down. Speaker driver has a similar design with voice coil moving up with electric signal applied and then being pulled down by the magnet.
Have you considered using a reed switch or a Hall effect sensor to commutate the current? Also instead of spring (magnet) on the idle end why not put a similar commutating circuit there too and double the output power? It would become a one-stroke engine! Speaking of which, what kind of power does it produce, have you tried putting some kind of load on it? Good effort btw.
Use an opto isolator switch and transistor in place of the the mechanical magnetic switch and you could fine tune the timing and duration of the coil energizing.
Hi, Could it be concluded that the amplitude of the oscilation is mostly affected by the intensity of current and the frequency is given by the second magnet?
Wooow! What about if you use the Gravity pulls to make work this linear motor? It would to be produce energy for charging capacitor/battery/or running a light lamp?
Simple answer is look up MAGTOR motor. All the AC, Frigs and dehumidifiers use compressors that use a ton of current and create LARGE amounts of Co2 the energy Co have a demand when we all use AC and all these Refrigerators are ON and being used. This motor idea you saw is how a MAGTOR works, it will become the new PUMP for all those units. Why is that great? Because MAGTOR uses much much less energy to start and to run. Peace!
Good concept but you are better to have two coils and turn one on at a time. This way the force going right is the same as the force going left. Here your magnet pulls the armature steel back at a different force than your coil is pulling the armature.
Looks like it! I was making a current balance for our physics lab (short thick copper conductor), and the easiest way to regulate DC current in that wire was to have a thin copper coil in series to act as the resistor.
By the way I tested the transfomer thing. It kinda works, but the transformer does not like the chopped, low frequency pulses and efficiency is horrible. Nevertheless it is interesting so I will upload video. Maybe it will work better with a relay.
That isn't a linear motor and what you made earlier wasn't a reed switch! But I don't care because I love your videos and wish you could make more. Best regards, Mike
I assumed the smaller coil in the supply line served as an inductor for this purpose. I'm embarrassingly ignorant to the ways of lightning magic though, so there's a very good chance I missed the mark on that.
@@jasonjohnson3282 Hi Jason... The coil generates a magnetic field when current flows. When the current stops, the magnetic field collapses and reverses the polarity of the coil. This current, if not redirected, returns back into the voltage source, and usually, that is not a good idea! A diode can be used to redirect the collapsing field away from the source. Current lags voltage in a coil by 90 degrees. The added small coil does nothing to redirect. The smaller coil will represent a different impedance than the larger coil thus may have been added to control the current draw. I am always open to being shown if I am wrong. I am always interested in learning something new.
@@valveman12 Thanks so much for your response and explanation! This stuff is so fascinating, but I'm still trying to wrap my head around the basics. This was very helpful.
Lazar Jakovljevic I mean if you use a.c., the reversing magnetic field in the coil alone can make the oscillation happen without using the third magnet, right?
If you use low voltage AC, say 5hz this motor will become much simpler and somewhat more useful if you want to make an actual motor out of it. One can become low frequency AC via variable frequency drives.
Solar panels, super caps and oscillation crystals. Just use frictionless (reduced) rotation of orbital planetary systems. If one sun can power life for a (lifetime*) then why not capitalize on physics outside of earth bound batteries.
Interesting. It's not a linear motor though. I would describe it as a reciprocating motor. Oh, I've just seen your description, "with reciprocating motion"...
one small question here: why use the coil? why not just put that rod with magnets on both sides inside a tube and put two repelling magnets on either sides? like..... | S N| -- |N S| -- |S N|
