Sliding gate Design

Sliding gate Design

(OP)
hi everyone,

i have slidig gate that i need to install a drive motor. the gate weight is 1500 kg and has 5 v-grove wheels. the dia. of the wheels are 160 mm. We already bought a motor for it but i am concerned about if that motor will be sufficient for this gate. i am trying to calculate the force required to accelarte the gate.
please see my calculations below and let me know if i am on the right track.

Rolling friction (fr) = C rr x Nf = 0.0005 x 15000 N = 7.5N
F - fr = m x a = 1500kg x 0.196m/s^2
F = 294N + 7.5N = 36.9N required to accelerate the gate

Motor Properties
Torque force = 1300N
Output revolution = 52 rpm
Pinion = Z18
Rated Power = 650W


I will be glad if someone can help me.

Situation is similar.  You're not accounting for all inertias that you must accelerate, and it doesn't appear that you are accounting for the acceleration / deceleration ramp times.

Websearch & download PDF file "Smart Motion Cheat Sheet" for all the usual formulas.
