Good day everyone,
I am designing a sort of winch system, where the user can pull the package freely, and once they are done, the winch reels back up the string around a drum. I would like to use a DC motor connected to the drum to reel back the string. This means that when the user is pulling the winch, the drum will spin in one direction (let's say clockwise), but when the motor is reeling back the string, the drum will rotate in the opposite direction (anti-clockwise). This also means that the motor - which is not engaged in the first part - will be forcefully spun clockwise, and then it will kick in and spin anti-clockwise afterwards.
I am worried that when we are forcefully spinning the motor in the clockwise direction, it will act as a generator. This means we are sending current back into the system - possibly damaging electronics. How do I overcome this? I was thinking we simply have a switch that disconnects the motor from the main system. This way we can forcefully turn it and allow it to act as a generator. Then we want to spin the motor anticlockwise, we just turn on the switch.
Thanks for your comments!
