Hi guys, I bought a high-torque DC motor, that says at the back: 6,000 (gf.cm). I am intending to use this motor to power a plinth on a turntable. So the motor will be upright, with its shaft pointing up. My question is - What is the maximum weight i can put on this turntable, where the motor will still be able to turn? (ie. what does gf.cm equate to in terms of kg?) Thanks so much for your help!
