Calculating the Motor Axis Load Torque (TL)
T
W
: Load torque (load axis, N·m)
F: External force (N)
D: Cylinder diameter (mm)
(Generally speaking, the force of friction is F =
µ
Mg (N).
µ
: Coefficient of friction
M: Weight of drive mechanism (kg)
g: Acceleration of gravity (g
≈
9.8 m/s
2
)
T
L
: Motor axis load torque (N·m)
Tw: Load torque (load axis, N·m)
Z1: Number of motor-side gear teeth
Z2: Number of load-side gear teeth
G: Gear ratio (reduction ratio) = Z1/Z2
