Hello,
I'm trying to size a motor for a project I'm working on, and I'm really confused. I have a flat square panel that I'm rotating, with the length and width parallel to the ground. The center of rotation is through the center of the panel, and perpendicular to the ground.
I've calculated the angular acceleration I need in radians/(s^2), and the moment of inertia of the panel in Kg*cm^2. So the torque I calculated has the correct unit of Newton meters.
But most of the motors I've found for sale list their rated torque in Kg*cm, which is not the same units as Newton meters. Do they actually mean kgf*cm? Or am I missing something?
Any help would be greatly appreciated.
these are my numbers in case they're helpful:
These are the dimensions of the panel:
H = 3.5cm
W = 62cm
L = 66.5cm
mass = 10.2kg
I got a moment of inertia of 7.033 Kg*cm^2 using I = (1/12)*mass*(L^2+W^2)
The acceleration I want is .314 radians/sec^2
The torque I calculated was therefore .11 Newton meters
