Low RPM, High Torque on dry cell batteries

AI Thread Summary
To achieve a torque of 0.6 Nm at 1 RPM using dry cell batteries, a suitable motor and gear system must be selected. Calculating the required power involves using the formula P = Tω, where torque is converted to angular velocity in radians per second. Recommendations include using Tamiya motors and gearboxes or Pololu metal gearmotors, while considering the potential need for a rotary encoder or stepper motor for precise control. The size of the gear system and motor will depend on the specific design requirements of the project. Overall, dry cell batteries can be sufficient for this application if properly matched with the motor and gear system.

Hello, Apologies I am not an engineer. I am hoping to find the approximate size of a system that rotates at a torque of 0.6nm but a rotation per minute of 1rpm. Ideally this would run off of dry cell batteries (e.g. 6xAA). Roughly how big would the gear system be to drop the RPM for this? How big would the motor be? Can you recommend any particular motor/gear system that would get the job done? Will dry cell batteries be sufficient? Any help at all in any of these questions would be greatly appreciated.
Thanks!

You can calculate the power required from the motor via:

P = Tω
Power (Watts) = Torque (Nm) * angular velocity (radians/s)

(Google how to convert rpm to rad/s)

If this is a one off project one of, or a combination of a couple of these may work:

Or you may need a rotary encoder.

Or a stepper motor (and maybe a small, single stage gear box) may be better.

It all depends on what your design needs to do.

That's brilliant Billy_joule, thank you so much for your prompt and helpful reply! The links are really useful and will definitely get me started. Thanks so much for your help!
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
Thread 'How can I find the cleanout for my building drain?'
I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
