I was wondering if anyone knew how much voltage runs through bumper cars when they are running. I searched and I really couldn't find anything (although 90V seemed to be suggested, I wasn't made clear) Anyone?
ZNitroMan said: If no one knows, I'll have to just stick a volt meter onto two wires, or wire hangers and stick 'em on the floor and ceiling during the ride :)
I can picture some one using a Simpson Meter(VOM), or a DMM on a bumper car ride. Plus I dont know how well that would work, because to measure current you have to break the circuit. ------------------ So you believe that you are studying us, then kindly explain why you are the ones trapped in your seats.
I always wondered what would happen if someone touched the floor on the new style one's that are powered by an electrical floor. The voltage can't possibly be too high, otherwise it would be a liability waiting to happen.

Touching the floor would probably be harmless, since that's going to be the ground (electrically speaking as well as physically). However, touching the "ceiling" and floor at the same time could be a different story.

Just wondering...is it a delusional memory from childhood, or did they used to run with considerably more force *back in the old days*...seems like you used to be able to get a solid BUMP on a bumper cars, now they all (except for KG's) seem to run a LOT slower...SFMM's was the same on the I-5 as it was in the park...bumper-to-bumper-gridlock, no acceleration whatsoever...;)
Greg, nelson is talking about the new kind of bumper cars that don't connect to the ceiling, a'la Buzz Lightyear's Astroblaster at Disneyquest (Or even WhirlyBall for those in the Chicago area) http://taddeo.4t.com/dqc5.jpg which are powered by parallel metal strips in the floor.
If my hunch is correct, nothing happens unless you touch two strips at the same time while the power is on. This is the way to complete the circuit... and as you know, without a complete circuit, there's no electricity.
Update: I did some poking around today and found a web page which includes a history of the Lusse bumper car. In that history it is suggested that the original Lusse cars were 110v AC and that the industry standard shifted to 90v DC. If that is the case, then I wouldn't be surprised if it's really 84v DC, the same as is used for many projection lamps, provided by simply rectifying standard AC.
I know that there are now battery operated models available, so I suspect that there are some 24v units out there now. So I don't think we have a definitive answer (anybody know anybody at Majestic we could ask?). But it seems that 90v DC is or at least was an industry standard.
A lot of the difference in the thunk available depends on the construction of the cars, not just the voltage used. Older cars had steel bodies with steel springs used on the bumpers. Modern cars have lightweight fiberglass bodies and air cushions. If you like the old cars, go to Knobels. They have wonderful vintage bumper cars.
When I worked at Great America, Rue Le Dodge had 5 settings in the back. They normally operated on level 2 (second lowest). On occasion they would run the cars for employees at a higher level after hours. However, after a couple motors burned out, they stopped soing that.
Actually, we used to play a basketball-like game called Rue-Le-Ball. Very fun!!!
I've wondered that too, Greg. I don't know where the contact strips are placed on the cars, but I have to assume that it's geometrically impossible to ever be out of contact with a hot and a ground. I've never managed to do it. I've wondered if maybe the same strip could alternate hot & ground, but that would seem much more dangerous that just alternating.
The floor-pick-up cars have a minimum of three brushes on them (I think they actually have four) which are tied into a network of steering diodes...in essence, the power comes in through a full-wave bridge just like the ones used for converting AC to DC. That way, any pole can provide any current polarity, and the geometry, as ThemeDesigner suspects, is such that at least one brush will be on each pole. What the motor (and lights and everything else) "sees" is plain DC.
One time my bother and I took a ride on the bumper cars. We both sat in the same car. He took the wheel, while I stood up and climbed on top the car to touch the ceiling. It wasn't a pleasant experience. -But, there sure is a lot of volts running through those cars! lol
That's proof positive that Darwin's Theory of Evolution isn't always true ;) ;)
