Magnetic Linear Motor

A very simple motor with reciprocating motion.

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

Dear Friends, this is the best! Simple and easy to construct. The information on its function is very good.

so much for there being a link in the description. I actually wanted to know how to make that switch.

Extremely helpful for my project thank you. This solved the problem i have been facing from past couple of months

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.

I find this strangely satisfying to watch run.

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.

Can you put a generating coil in between the magnet and electromagnet coil

[amitskanda]

Great video but was waiting for you to raise the voltage to 12v lol.

thank you for making this knowledgeable video

Buen ingles Manuel y te felicito y gracias por tus videos ..

Nice 👍🏼!! An alternative is to put a Reed switch on the other end

[nunoostephen]

Good job that can be made to turn a crankshaft

[roykoffi]

Kind of a relay system.You’re awesome man

[fredriko.zachrisson]

Cool. I have always wanted to make a replica of the Gap Power device since i first saw it online a few years back.

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.

Looks more like a solenoid to more than a motor

What about the collapsing magnetic field?
Can you recover that as well?

[АнатолийБеляев-бу]

Хорошая идея использовать магниты вместо пружины!

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.
