(1) Max. traveling speed (v)
If the reduction ratio is 1/1 and the rotation speed of the motor shaft is 3000 [r/min]
v = (3000/60) × 10×(1/1) = 500 [mm/s]
(2) Load inertia converted to motor axis (J
L
)

Screw (J
1
) Suppose Ø20 and 500 [mm] in length.

Moving parts (J
2
) Suppose a transfer mass of 20 [kg].
(3) Load torque converted to motor axis (T
L
)
Suppose a transfer mass of 20 kg, friction coefficient (
µ
) of 0.1 and machine efficiency (
η
) of 0.9.
