How to calculate loads of Harmonic geared type
Use the calculating formula below for the axial load and moment load of Harmonic
geared type.
Example 1; When an external force F is applied on the position of distance
L from the center of the output flange
Axial load: Fs [N] = F + mg (Load mass)
Moment load:
∆
M [N·m] = F × L
F [N]
L [m]
Load mass: m [kg]

Moment load:

M [N·m]
Example 2; When external forces F1 and F2 are applied on the position of
distance L from the mounting face of the output flange
Axial load: Fs [N] = F1 + mg (Load mass)
Moment load:
∆
M [N·m] = F2 × (L + constant a) *
* Motor frame size 51 mm (2.01 in.): constant a = 0.0129 [m]
Motor frame size 61 mm (2.40 in.): constant a = 0.0140 [m]
