Urgent Search for 12V DC 1/3 RPM Motor for Telescope Mount Design

Click For Summary

Discussion Overview

The discussion revolves around the search for a suitable DC motor for a telescope mount design, specifically one that operates at 12V and approximately 1/3 RPM. The focus is on motor specifications and potential solutions for achieving the desired speed.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses an urgent need for a 12V DC motor that operates at less than 1 RPM for a telescope mount design.
  • Another participant suggests the possibility of using a geared motor to achieve the required RPM.
  • A participant mentions having attempted to gear a motor but encountered difficulties in reducing the speed to the desired 1/3 RPM.
  • There is a request for elaboration on the problems faced with the gearing setup.
  • One participant notes that 1/3 RPM is quite slow and questions the availability of a motor that can achieve this speed without gearing.
  • A suggestion is made to consider a motor that rotates one revolution per day, with a link provided for a potential supplier, although it is noted that custom requirements may incur higher costs.
  • Another participant expresses gratitude for the suggestion regarding the motor supplier.

Areas of Agreement / Disagreement

Participants have differing views on the feasibility of achieving the desired RPM through gearing, and the discussion includes both suggestions for alternative solutions and acknowledgment of challenges faced.

Contextual Notes

There are unresolved issues regarding the specific problems encountered with the gearing setup and the exact requirements for the motor, which may depend on further clarifications.

I think I'm going to need (( 12 V DC 1/3 rpm ))


please if you can help me !

Why couldn't you gear one to give you the required RPM?

acctually I tried to do that

but I faced some problems with reducing the the speed

and now I need about 1/3 rpm
 


Faced some problems? Could you elaborate?

Perhaps someone could help seeing as you already have that setup.

1/3 RPM is rather slow and I'm not sure if you can get a motor for that speed without gearing.
 


Hi,
Here (at the industry) I've seen a motor that rotates only one revolution each day. You might ask them for your customized requirements. But it would cost more. Here's the link:
