Stop And Start Going Round In Circles.
This not a bulk handling topic. However the most important issue of stops and starts has been overlooked.
You need to do a lot more homework; find out the parameters and then approach a fairground constructor.
At Nottingham Goose Fair (est circa 1284) I pointed out to the showman that he could almost double his takings by installing 2 loading decks on each side of t.d.c. but he was too busy taking money to realise what I was saying. It also halves the acceleration interval frequency which will be quite important with your monster. ■

Going Round C/W People
Hello Shaks,
i'm sorry but i feel your approach is not a sufficiently professional one on this issue. You talk about some high end engineering: The design of mobile equipment destined for the transport of persons. Besides some solid design knowledge in this discipline, you shall need something more than one formula (and one engineering discipline's knowledge) to get the results you need.
Also, this here forum handles bulk transport issues, and the specific background you seek will be rather scarce.
I'm rather sure, even if you meet someone willing to talk generals, a diligent engineer (as John did) will point you either to the entrance of an engineering school or else to a relevant and knowledgeable supplier.
Finally, consider the situation you understate: You want to design a ferris wheel on the base of a formula you got in some forum on the internet, just like that.
I hope you catch my drift correctly and come to the right conclusions, so i remain, with
Kind regards

Hmmm. You have certainly posted this query on quite a few forums.
As mentioned above, this isn't really the right forum for a question like this. ■
Calculating Torque and Required Motor Power to Rotate a Ferris Wheel
Hi Guys,
I am pleased to join this forum to learn something from experienced guys and thanks in advance for helping me to understand physics.
I am trying to design a Ferris wheel with maximum SPEED and maximum PASSENGER capacity. I want to know formula to calculate MOTOR POWER IN KW to rotate that Ferris wheel. Here are general specs of the wheel.
Diameter: 106 Meter
Radius: 53
Wheel total weight: 1000 Ton
Exclude Wheel standing structure: 30%
Rotating Wheel weight: 700 ton (Everything including spindle, hub, bearing, spoke cables, rim, cabin, riders weight, etc)
Minutes Per Round: 10 (1 round completed in 10 minutes)
Round Per Minute: 0.10
Wheel Speed: .55 meter per second
For this calculation if only rim, spoke cables, cabin/rider weight is required then you can make rough estimate what might be the weight of spindle, hub, bearing, etc. which are creating force. You can make an assumption and then calculate on that assumption. I will fix formula in Excel as per given here and then adjust weight.
I want to know
1. What is total torque generated by wheel (Newton Meters / Joules)
2. What power motor in HP or KW I needed to rotate this wheel
Once I get formula then I can set that formula in Excel and try to change speed to find good results.
Please help me.
Thanks
