Power

[Ilovthevu']

Which ride in your opinion uses the most power to work?
I would have to say that D Vu needs the most power because of the force that it put on the cables in the 90 degree angle. My second would have to be V2 because of the speed. Third would have to be Whizzer because of the lift and all the little motors.

Someone once told me that D Vu does not have a generator. On a white box like near the ride, there is the name Kohler. So, I checked the website out and they make generators. Funny coincedence. I also can hear the blue and green box humming. However, that could be the water. http://www.kohlerco.com

Someone also told me that would absolutley stupid for every ride to have a generator. This is probably true, but on IW it looks like it has one also. It is green and looks like the shape of a oil tanker. The only way I know that this could be a generator is because I go to carnivals also and that's how they generate there power, through what this looks like. However, it is bigger because it's just not one ride. I'm sure other rides also have one, but can't be seen.

Lastly, how much the power does the whole park need to operate? Considering that I'm not skilled in amps, volt, and other stuff, compare it to something like Wrigley Field, or Gurnee Mills.

I think Deja Vu uses the most, but I remember when the blackouts happened a while back, they shut down the rides that used the most energy and it was Vu, V2, and sky trek tower( i dont remember what else or if that was it)

[Virtua Tennis]

Superman The Escape. By far. No ride will ever waste as much power as that (even with 1 side open).

[Timmy179]

pshh v2 and whizzer take the cake, and beat Vu by a longshot.

[DejaVu The Ride]

How could Vu really use the most power? Definately V2 uses the most.

Superman The Escape. By far. No ride will ever waste as much power as that (even with 1 side open).

It doesn't get the chance to waste power because it is never opened to do so .

After working an Impulse, I would have to say that V2 uses the most power in the park. When S:UE would launch sometimes it would cause power failures in the park (SFWoA). I hear that each launch uses around $50 worth of power. That is speaking in terms of SFGAm, but I do believe Virtua Tennis is right when he says that S:TE uses the most in the entire industry (when it's open).

[sfgamer2]

Yeah V2 and Whizzer. V2 because of the LSMs and Whizzer because they have motors in the bottoms of the cars to get up the chain lift, that is why the chain lift on whizzer is just sharpe things. I guess there isn't a chain lift.

[Virtua Tennis]

that is why the chain lift on whizzer is just sharpe things. I guess there isn't a chain lift.

The motors and the anti-rollbacks are diffrent.

[sfgamer2]

okay

Is that what the so called chain lift on whizzer is called an anti rollback?

[planea380]

V2 has LIMs.....Superman the Escape@SFMM has LSMs. Whole different technology.

[sfgamer2]

I read in a book that V2 had LSMs.

[Virtua Tennis]

Don't feel like explaining so i'll copy paste:

Linear Induction Motor (LIM) Launch - Launch mechanism introduced by Disney. Premier Rides was the first to introduce the LIM launched roller coaster.
LIMs are electric motors which create linear (straight line) motion. Conductive aluminum fins are located on each side of the train and stator (electrical) coils are located in a series of anchored motor housings which extend out from beneath the loading platform along the track to more than 200-feet, ending at the base of the first hill/element. An electrical current pulses through the stator coils, which in turn creates an electro-magnetic force that pulls at flat metal bars, accelerating the train out of the station. As the train accelerates, each fin passes between a pair of stator coils which are powered consecutively in a time sequence, pulling the train forward till it reaches its maximum speed.

Example: Flight of Fear, Paramount's Kings Island

Linear Synchronous Motors (LSM) Launch - Launch mechanism first used by Intamin AG.
A series of extremely powerful rare earth magnets are mounted on the car. Linear motors, which are placed on the track, are activated by electricity. The motors then create magnetic fields which pull the car forward by attraction. Magnetic fields also repel the magnets which are mounted on the vehicle, increasing speed.

Example: Superman: The Escape, Six Flags Magic Mountain

V2 uses LIM's by the way.

[sfgamer2]

Oh I was wrong. I thought I read in my book that it said LSMs but it really said LIMs

[Mr. SFGAm]

okay
Is that what the so called chain lift on whizzer is called an anti rollback?

If you've ever noticed on Whizzer's lift, there is a third 'rail' that runs up the middle of the track. This 'rail' is electrified. When the trains(motors) come into contact with this, it electrifies them, therefore propelling the train up the lift. (At least that's how I came to interpret it, I read it in a book. Correct me if I'm wrong).
As for the anti-rollbacks, almost all coasters have them(except V2 and Vu). It is not a means of lift, it is a ratchet strip that is there to stop the train from rolling back down the hill if the chain or motors should fail. That is what makes the clanking sound as the train progresess up the lift.

[Timmy179]

The clicking sound is the chain dog moving from one notch on the anti rollback strip, to the next.

[twixmix0303]

I always thought that V2 worked more like an LSM, but it's an LIM. LSMs seem to use much less power (if I'm correct, they're powered mainly by polarity of the magnets, and not by a magnetic field created by electricity).

[coasterzak]

I would think that LSMs would use more power - if S:TE really uses as much power as everyone says, I would think it would be LSMs over LIMs.

[twixmix0303]

I don't have a definate answer, but all the sites I've seen conclude that LSMs are more efficient than LIMs.

[sfgamer2]

I was gonna say that.

[coastrcorey]

LIMs are simpler than LSMs but are less efficient.

[Supreme_Overlord]

here's the deal between LIMs and LSMs

LIMs are much simpler, and cheaper to build, Where as LSMs are much more complex and more expensive.

In terms of power consumption, a Single LSM motor uses less power than a single LIM motor but also produces much less acceleration.

Therefore, you will need alot more LSMs and a longer area to launch.
Example(I'm making up numbers): Let's say you have a ride that goes 50 miles per hour. To get it up to speed it will need 20 LIMs or 35 LSMs. Lets also say that for each launch it costs $1.00 per LIM or $0.75 per LSM. It would then cost $20.00 per launch using LIMs compared to $26.25 using LSMs. So despite being more efficent, it costs more per launch to use LSMs.

Also I believe that LSMs can only produce force in one direction (ok for S:TE but not for v2 where it accelerates you backwards).

Now back to the topic. V2 Uses the most power, and Wizzer actually is on the lower end. All of the rollercoasters (except v2) have eletric motors somewhere. These are usually at the bottom of the lift hills. Wizzer Uses less power than there rollercoasters (RB for example) because:
1) The motors only run while a train is on the lift as opposed to other coasters where it runs continously
2) The trains on Wizzer are significantly lighter / less massive than just about any other train at the park
3) The lift hill has a gentler grade(angle) than any other lift hill at the park. This means that the motor has to do provide less force on the train to get it up the lift. Which allows them to use smaller less powerfull motors. And as a general rule smaller motors are more efficent than larger motors.

The only thing I can think of that would increase the cost of wizzer is the age of the motors it's using. Older motors are less efficent than newere motors because as things age they just get less efficent, and because technology has improved. I still don't think that this would increase the cost of running it higher than a larger more modern coaster.

One last thing.
There is a generator near Deja vu. It is there incase power goes out and the train is still on one of the towers.

The End
*sorry about the novel*

[Ilovthevu']

You forgot to answer how much power the whole park would use compared to a Wrigley Field or a Gurnee Mills Mall.

There are more motors than just the lift of the Whizzer. They are in quite a few places. I know that at least IW, BTR, and RB lifts shut off after the train is done is going up them. However, I believe that even the big tires shut off on IW too. I believe that BTR and RB little tires are always on before the lift hills.

If you are saying that since the lift hills are on an angle, that means that they need more power than Whizzer. D Vu must need even more because they are two vertical "lift hills". The way I look at it is pushing a 50 lb box up a slope compared to lifting it. Yes, a pulley (wheel on top) does help somewhat reduce the weight, but that is still harder to lift something than "push" it.

[twixmix0303]

Yes, Vu needs more power than most other coasters, however, you also have to take into consideration the size of the train, as Supreme_Overlord said. All motors are made differently, so some will also be more efficient than others.

[playerplex]

So its V2 then.
