I'm trying to calculate the torque of my model so i can correctly spec a motor to rotate it. As we all know, t=Ia where 't' is torque, 'I' is moment of inertia, and 'a' is the angular acceleration.
The mass is going inside a torque motor... think of the motor as a donut and the mass as a munchkin spinning in the middle, however the mass is not symmetric.
Center of mass: ( millimeters )
X = 0.1283
Y = 3.6911
Z = 0.4753
I have centered the model such that it will rotate at the output coordinate system about the Y axis like it would in real life.
Moments of inertia: ( grams * square millimeters )
Taken at the center of mass and aligned with the output coordinate system.
Lxx = 9009.2180 Lxy = 116.3216 Lxz = -179.7757
Lyx = 116.3216 Lyy = 9102.2187 Lyz = 86.0433
Lzx = -179.7757 Lzy = 86.0433 Lzz = 10804.8404
What values do I use to calculate the torque?! What is their naming convention for their variables?!
NOTE: The velocity is going to be 120 RPM, but I haven't yet figured out the actual acceleration.
