What gears to use to reduce fan speed from fast moving motor

AI Thread Summary
To reduce the fan speed for better visibility of each blade panel, a gear system with a belt is suggested. Key information needed includes the desired RPM of the fan, the length of the blades, and the RPM of the motor being used. The type of motor, such as whether it is an AC induction motor, is also crucial for determining the appropriate gearing. The requirement to see each panel on the blade is noted as unusual, prompting questions about the design choice. Clarifying these specifications will help in selecting the right gears for the project.

hey, I am building a fan, but I need the fan blade to move relatively slow, slow enough to see each panel on the blade. I am expecting to use a gear system with a belt. What gears should I use to active this?

Welcome to PF.
First we need some actual numbers.
What fan RPM do you require ?
How long are the fan blades ?

What is the RPM of the motor ?
Is the motor an AC induction motor ?
 
Slow enough to see each panel of a blade is a very unusual spec. Why have you assumed your blade will be made of multiple panels rather than single pieces? And why do you need to see each one?

Thread 'Turbocharging carbureted petrol 2 stroke engines'

Hi everyone, online I ve seen some images about 2 stroke carbureted turbo (motorcycle derivation engine). Now.. In the past in this forum some members spoke about turbocharging 2 stroke but not in sufficient detail. The intake and the exhaust are open at the same time and there are no valves like a 4 stroke. But if you search online you can find carbureted 2stroke turbo sled or the Am6 turbo. The question is: Is really possible turbocharge a 2 stroke carburated(NOT EFI)petrol engine and...

Thread 'HP Required to move a robot 10meters at 1.5m/sec'

I need some assistance with calculating hp requirements for moving a load. - The 4000lb load is resting on ball bearing rails so friction is effectively zero and will be covered by my added power contingencies. Load: 4000lbs Distance to travel: 10 meters. Time to Travel: 7.5 seconds Need to accelerate the load from a stop to a nominal speed then decelerate coming to a stop. My power delivery method will be a gearmotor driving a gear rack. - I suspect the pinion gear to be about 3-4in in...
