Conveyor Power & Ratio

Motor power for horizontal, vertical and inclined conveyors plus the reduction ratio from sprocket teeth.

Total load weight (kg)

Conveyor speed (m/min)

Track friction coefficient

Drum/belt efficiency

Gear/reducer efficiency

Service (duty) factor

Driven sprocket teeth

Motor sprocket teeth

Motor rated speed (rpm)

Incline angle (deg)

Formulas

i     = Zd / Zm
v     = vs / 60                [m/s]
P_h   = W·g·μ·v / (η·1000)     [kW]
P_inc = W·g·(sinθ + μ·cosθ)·v / (η·1000)
P_v   = W·g·v / (η·1000)
P_sel = max(P_h, P_inc, P_v) · kd

Multiply the computed power by the service factor and add margin when selecting the motor.
