Angular Acceleration

Required torque and angular acceleration for a rotary (non-screw) motion profile.

Rotation angle (deg)

Reduction ratio

Positioning time (s)

Accel/decel ratio

Load inertia (kg.m2)

Safety factor

β = 2θ / t_acc²     (output angular accel)
T = J·β
T_S = 2·T ;  T_M = T_S·S

If inertia ratio > 5, use a reducer to improve matching.
