Hi, I need to wind up a rope around a 4" wheel pulley that is mounted on both sides of the motor shaft. This is to assist a disabled person to pull ropes in and out on a sailboat. It would be lifting the equivalent overall weight of about 15 lbs and maintain around 45 rpm. Will this motor/gear accomplish this ? 12V 160RPM High Torque Dual Shaft 31D Motor with Worm Gear Reduction. If this isnt strong enough, please recommend what is. I need 12VDC. I need it to be able to got in clockwise and counterclockwise directions. Thank you
Hello @Jasonh1965 and welcome to the RobotShop forum!
The motor you mentioned is probably not powerful enough for your application.
This one could be a better option:
But you can also find others in the Gear Motors (Rear Shaft) section.
According to my calculations, you should be looking for a 3.4Nm ~ 35 Kgcm motor.

Thank you for responding. The existing drive indicates 32 in-lbs and its way too powerful. These values are reverse to typical lbsin or kgcm you indicate. Can you give me the equivalent to 10 in-lbs ? Thank you
Not sure if I understood correctly but in case you asked how many Nm are 10 in-lbs then the answer is ~1.13Nm.
You can use this online calculator for this.
Thanks. That is what I needed. So the 3.5nm would be too powerful. A 1 -1.5nm would suffice. I’ll check the website for this torque option.
