Hello I am kicking around an idea in my head. And needing some thoughts on how to pull off a particular feat.
Suppose I have a motor mounted to a table, and on the end of the motor I have a cable wrapped around the shaft. This cable goes to the ceiling and gets looped through a hook and then back down to the table.
The free end of the cable can be attatched or detached to different weights. If you want to lift a 1 lb weight off the table say 1 foot, you would select one setting that is calibrated to only lift one pound (no more).
If you wanted to lift a 2lb weight off the table 1' you would use another setting. What ever weight, say up to 5lb you could hook up and it would lift it 1' off the table without burning out the motor. (pull the weight up and hold) Hopefully in the hold mode, it is not consuming lots of electricity??
I need this device (stepper motor?????) to be able to kick in, lift and hold with minimum amount of electricity and on my wish list is it runs on DC.
I do not want the 5lb setting to be used every time, each setting has a maximum amount it can lift.
This example may not make sense because it is a super sensitive invention I am working on in my mind. In reality I am not trying to lift something off a table with a motor, but I figure if I could tackle this feat then it would transfer over to my invention.
Anyway thank you for any comments, input, or direction you can suggest so I can start my research.
Thanks again
