This is correct, but the motor would need to be attached to the same shaft that the material is on, no? Then the motor would limit the free spooling ability. The closest solution that I can find is a coaster brake hub on the bike, but only using the "neutral" state, and what would be the...

Similar yes, keeping the pull out force minimal is why a rotator spring was not pursued. As well as this spool needing to roll out about 7’ of material. So yes, the material is a fixed length and not consumed. The material is pulled up, and in reference to the image, to the right, so both...

Thank you for the reply, Here is a quick mock up to hopefully get a better understanding, I can provide a more detailed image in CAD at a later point if needed. Here the motor is depicted as direct drive, note this does not need to be the case. The retractive force for the motor is around 5...

I am working on designing a roller which contains a spool of material which can be pulled out by hand (Freespin) and then retracted back in by a motor. The first thought was to use a one way (Sprag) bearing but this will not work as the free spool direction is the same as the driven thus only...
