Low RPM high Torque Motor with enough power to rotate 30 pounds?

[kakashi1027]

Hi, I'm working on an engineering project and I need to get a 30pound base to rotate at speeds between 6 rotations per hour and possibly 1 rotation per hour.

Does anyone know where to get such a motor, or if it is even possible?
Can anyone think of a better more efficient way of doing this task?
Thanks!

30 lbs? That's all?
1-6 rph? That's VERY slow.
Not sure why there is any problem.

A "winch" motor comes to mind, as it can be very slow.
Cheap and widely available for less than $100.

for the winch motor, what kind of power source do I attach it to?

DC. Car battery.
In your case, the load is so low that a very small car battery would work just fine.

Edit: Of course, with such a low current load, a simple AC/DC converter rated to your specs will work as well, with the benifit of just plugging it into your AC wall outlet.

I would recommend using a low RPM high torque motor with a gear reduction system. This will allow the motor to have enough power to rotate the 30 pound base at the desired speeds. It is possible to find such a motor, but it may require some research and possibly custom ordering. Alternatively, you could also consider using a stepper motor or a servo motor with a controller to achieve the desired speeds and torque. Another efficient way to rotate the base could be to use a pulley system with a motor, which can provide the necessary torque and speed. Overall, it is important to consider the specific requirements and constraints of your project to determine the best and most efficient solution.
