With this guide, you can determine the ideal torque in Newton meters (Nm) for the shutter motor.
DETERMINE WEIGHT ROLLER SHUTTER
1.) Determine roller shutter area
(Height + 150 mm) x Width = Roller shutter area (m²)
2.) Determine weight roller shutter material
Take approximate weights per m² of roller shutter area
from the table.
3.) Determine weight roller shutter
Roller shutter area (m²) x weight roller shutter material (m²)
4.) Calculate required traction force
Friction losses must be taken into account
(rail guidance) of approx. 10%!
Roller shutter area (m²) x Weight roller shutter material (m²) = Weight roller shutter (kg) + 10% Friction losses = Required traction force (kg)
Example:
PVC-Roller shutter area 3,00 m² x Weight roller shutter material 5 kg = 15 kg Weight roller shutter + 10% Friction losses = 16,5 kg Required traction force
