basically I am making a spirographic drawing machine, where spinning disks will rotate and push, pull, and move rods that are connected to a pen on a large drawing surface to pull and push the pen around creating cool designs. So the motors need to spin the disks that have the rods to push the...
thats a great idea, but a whole a whole complicated expensive design, I was looking for cheap small 12v brushless motor 100rpm or less that I can use a PWM motor controller with for speed modulation. that's why I asked about how to calculate torque. I know what wheel setup I want to turn, but DC...
I need a 12v DC with appropriate torque. In my design, the axle of the motor would be pointed straight in the air and I want to affix a wheel to it and have the wheel spin flat, sort of like a pottery wheel sort of design. I know what the wheel is made of, its dimensions and approximate weight...
