Linear Motor Demo

This is my lab built linear motor. The supply is a 1 phase to 3 phase 120V VFD. The coils are 150 turns of enamel wire. The “rotor” is an aluminum plate.

The metal core is my own design and was laser cut from 1/8in steel at Loftis Steel in Nashville TN.

Now i finally understand the maglev car's basic working

Stacking two of them with a gap between them, and you have yourself a rail gun

It's a 3phase linear induction motor. Perfect ❤️❤️❤️

Lenz’s law is strong with this one. Don’t use your hands, use the force derived from it.

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.

what will happen if instead of using a bar-shaped rod he uses a ring, will it cause revolutions?

Now.... Put another one on top of the other with a gap for the metal to go through and now you have your very own mail gun ^^

cant wait to drive one of these down the interstate

Now to hide it under a table and hand someone a metal tray of hot drinks to put down. Mission complete.

Hi, nice project you got there.

ur coil is in star or delta configuration? Seems like star.

[TheMono]

U shud try that with a bandsaw blade see if u can get it moving a constant loop

[tarodchaoslord]

I see that cheeky little ideal pushfit, love those

Eu tenho um sistema de porta deslizante com o sistema de motos linear, maglev. É muito silencioso

After watching a billion versions of the "Magnetic River" video, this was recommended to me lol.

[headbanger]

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?

It might turn out to be an induction heater if the frequency is too high.

Look up Eric Laithwaite from 1971 he had this device in his lab at the Imperial College in London

[TheNynja]

uma otima demonstração amigo. continue com estas demonstrações pois ajudam muita gente.
alguns podem achar bobagem mas quem esta em busca de conhecimento é sim muito util. parabéns

I don't think electroBoom needs to rectify this tho...

[JonathanZigler]

Just like my power systems course used to talk about.
