6. Calculation of maximum velocity (Vmax)
× Acceleration time × Vmax + Constant-velocity time × Vmax + × Deceleration time × Vmax = Travel distance
× 1.0 × Vmax + 1.0 × Vmax + × 1.0 × Vmax = 1
2.0 × Vmax = 1
Vmax = 1 / 2.0 = 0.5 [m/s]
7. Calculation of motor velocity (N [r/min])
A single rotation of pulley : › × P
D
= 0.157 [m]
N = 0.5 / 0.157 = 3.18 [r/s]
= 3.18 × 60 = 191 [r/min] < 200 [r/min] (rated rotation speed of GP series 50 W, gear ratio 1/15)
