What Motor Setup is Needed to Rotate a 75 lb Cube at 6 RPM?

[PortCityMardiGras]

TL;DR

First time here, with basic understandings. Im building a front end for a mardi gras float.

It will be 2 rubiks cubes stacked, with the top cube standing on an axis. I am looking to make the cube rotate on axis. I have a lazy susan that the platform, picture of smaller concept of platform included, will rest on. This should help minimize friction. Total weight of top cube and stand is 75 lbs. I need to know what type of motor setup would be needed to spin this at 6 RPM. I am currently looking at a 12v dc gear motor, but the size itself looks as though it would burn up. Any help would be much appreciated. Thank you

Your best bet is to build the system, then measure the torque to rotate it. Be sure to look at worst cases: tilted sideways, tilted uphill/downhill, somebody stumbling against it. You measure torque with a spring scale and multiplying by the distance from the attach point to the center of rotation. Take the resulting number, multiply by a safety factor, then look for a gearmotor with the right RPM and output torque.

Thank you. I will finish assembly and locate a spring scale. Thank you for your time
