How to select your tubular motor

 

Expressions:

Torgue=Radius*Load/100*Safety-factor

The Nominal Torque is denoted in Nm (Newton per meter)
The rolling tube radius should be contained the shutter slat thickness.

For example

The rolling tube radius: 30 mm
The shutter slat thickness:
5mm
The load:
40 Kg
The Safety of attrition quotiety and friction:
From 1.2 to 1.6 times,

Torgue=radius*load/100*Safety-factor
? Nm =(30mm+5mm)*40kg/100*1.6=22.4N.m
So you can install our Yygl-25 tubular motor on this shutter.
