SUMMARY

The discussion focuses on methods to reduce the RPM of a 1.5-3V motor for use as a winch. The user, WidgeT, discovered that using mechanical gears, specifically worm gears, is more effective than reducing voltage or employing pulse width modulation. This approach enhances torque and allows for better control of the motor's speed. Additionally, the user seeks a solution to enable the motor to lock when current is removed, further emphasizing the need for a reliable mechanical solution.

PREREQUISITES
  • Understanding of DC motor operation and specifications
  • Knowledge of gear systems, particularly worm gears
  • Familiarity with basic electrical circuits and battery usage
  • Experience with mechanical applications in hobby electronics
NEXT STEPS
  • Research the design and implementation of worm gear systems
  • Explore torque calculations for DC motors with gear reductions
  • Learn about motor locking mechanisms and their applications
  • Investigate alternative methods for speed control in DC motors
USEFUL FOR

This discussion is beneficial for hobbyists, robotics enthusiasts, and engineers working with small DC motors, particularly those looking to optimize motor performance in mechanical applications.

Ok so I posted a question before and it didn't get answered, however I am very tenacious and read around on the net for about 4 hours and finally got my answer. My new question is this: I went to Radio Shack and bought a 1.5-3v motor, I have tested it and it works with my AA battery (as I expected it should). Now my newest problem to arise is that since I am using the motor to act as a winch if you will, I need to slow it down.. Even with a much wider apparatus on the spindle it still is much to fast to do what I want it to do without damaging the motor itself or the actual item to be lowered.. Also, the motor doesn't lock when the current is removed, is there a way I can set it up to do that also..?

That is the function of the motor only my container may be slightly larger..

Thanks in advanced

Toy and hobby stores sell motors with attached gears. They are just plastic gears, but probably rugged enough if your load is not too great.

This is better than trying to slow down a motor with reduced voltages or pulse width modulation as the gears produce much better torque.
 
A worm gear should solve both problems.
