SureTrack Users General Discussion

[Nick_Taylor]

Hey guys, do you want me to start a new general discussion thread if this gets too long or do you want me to just let it go as long as it can. I actually don't know if the forum has a limit to how many pages a discussion can go on.

Nick.

I say let it grow, of course I would be one to grow something

[greasybob]

Let it go and let it grow, it doesn't seem to take any longer to load, maybe it will get long enough and we'll go into unchartered territory and bring the whole web crashing down.
I was thinking maybe get a hulu hoop and wrap it in copper wire then spike up the voltage with more batteries and maybe bigger magnets. I wonder what the best magnet to voltage ratio would be ? Do the magnets need to make contact with the copper wire or would the plastic hulu hoop be to much air gap ?

[liljoe]

The magnets need to contact the wire coil, the magnetic field is created between the two magnets on the ends of the battery and it is out of phase with the magnets on the ends of the battery, this out of phase condition is what propels the train forward.

Thanks for the reply and explanation, my other thought was to energize the copper coil and use a steel ball..... hmmmm ?

Id have to look at exactly whats happening here, but in real world applications, "maglev" magnetic levitation/suspension/propulsion systems dont require any contact, this is the primary benefit. No friction/mechanical wear of the track or train and no mechanical transmission of vibration/noise.

[liljoe]

For that to work you would have to be able to energize small parts of the coil at a time to create a single magnetic field that would pull the ball then collapse the field and create another one just ahead of the first and so on.

[liljoe]

The cool thing with this set u is that the field is constantly moving due to the battery moving, the field is only created in the part of the coil that has current flowing in it.

so, Daughter comes home 11:30 at night telling me their's a bad noise in her explorer. going for a ride not even 1/2 down the block backed up to the house and told her that is preaty bad, bring it to work and I'll check it out. Next morning I get a call from her stating now it is making even more noise and pulling to the right. "Well bring it up so I could look at it". I can't she said, I'm on my way to take her friend home, wich by the way is 25 miles one way, by hwy. and hangs up. 10 min later ph rings again with now the truck caught fire and broke down. Sent tow truck to get truck. Arrive at shop to find tire leaning in and back. driver said wheel is locked up. Needless to say nothing left of wheel brg. axle frozen solid and boot melted off ( fire) rotor junk, caliper and caliper bracket distorted form the heat!!!! now the question. "When the heck did it and how long ago was it making noise?" reply???? yup, That just started 2 days ago. "Realy? (nodding my head) hummm" Takes me to another one of my sayings. Cars don't lie, people do.
Nick, lets do the test and see how long a post can be.

Mac Greasy spoon bob, me/flock did a 2000 f150 heater core-blender door in 32 minute yesterday. A dude from Camden,SC. He was amazed and me too. It just plain went well. The dash was coming back at 7 to 8 minute dept.
Think me should be teaching others how to.??

Today I had them replace the heater core on my 2000 Ford F150 and they pulled my dash and little over 7 minutes and took out my heater core and 11 minutes and they were done in 38 minutes with some talking to the boss for 5 or 6 minutes. No rattles and it was a nice job and they were the nicest guys. I drove 125 miles one way but it was worth it. and you can watch.

On the maglev the train has electro magnets as does the rail, the current is controlled by a controller and it moves the field to create movement. In one of the machines I work on it has a linear motor which consists of a shaft with alternating magnetic poles along its length and the part of the motor that goes around the shaft has four coils in it that are independently controlled and the controller switches current from one coil to the other to make the carrier move, one coil moves it a bit then the next one turns on and moves it a bit then the next one. By the time all four have moved it the carries is at the next section on the magnetic shaft and it starts all over again. The controller has great control over the speed and position of the carrier.

[liljoe]

For levitation and movement you need two opposing magnetic fields to push away from each other. You can create movement with one field and a metal object to get pulled, but cannot create a push action without two fields.

thats all also very very similar to the way EC or "brushless" motors work.

Man , if my theory works , you could go into an MRI machine at Cape Canaveral and Exit 2 minutes later in a hospital in Houston.LOL

The same principles apply, this is just a brushless motor laid out in a line instead of a circle is all.
