u How to calculate axial and moment load
Caution : • Do not apply excessive load to the Motor.
An excessive load more than specified in Table 4-2 may result in premature
Motor failure.
• Followings show how to calculate the loads.

F
If F is an external force, then
•
Axial load Fa = F + weight of payload
•
Moment load M = 0
F
If F is an external force, then
•
Axial load Fa = F + weight of payload
•
Moment load M = F × L
F
If F is an external force, then
•
Axial load Fa = weight of payload
•
Moment load M = F × (L+A)
