[When load torque affects]
Used as shown in the figures below should have the load torque by the gravity work on the
unit, thus the allowable inertia moment drops for the same amount. First, calculate the load
torque and obtain the corrected allowable moment of inertia. Calculate the moment of inertia
in addition to check if it is within the allowable inertia moment.
● Step 1 Calculating the load torque T
T = mgr × 10
-3
[N·m]
m : Loaded weight [kg]
g : Gravitational acceleration [m/s
2
]
r : Distance of load gravity center [mm]
● Step 2 Calculating the allowable moment of inertia correction factor Cj
Cj = (Tmax - T) / Tmax
Tmax : Output torque [N·m]
Example
Load gravity center: offset from center of output shaft
Installation of unit:
Horizontal - horizontally oriented wall mount / vertical orientation
T
