Maximum rotating velocity:
Angular acceleration of the ball screw:
Ball screw weight:
Moment of inertia of the ball screw:
Moment of inertia of the ball screw + coupling:
Accelerating torque and decelerating torque for the ball screw + coupling:
Preselecting the motor
Based on the calculated t
orques, if we select the 1FL2306-2AC motor:
n
n
= 2000 rpm, M
n
= 4.78 Nm, J
motor
= 1.326 × 10

Then the inertia ratio:
Wherein, J
W
is the moment of inertia of t
