To choose the right tubular motor there are some points to consider.
We describe the most important ones.
Our Superrollo tubular motors are available for two shaft sizes.
40 octagonal steel shaft = motors with the designation RMxxMSx(the S stands for small)
60 octagonal steel shaft = motors with the designation RMxxMMx (the M here stands for medium).
Control by switch/timer or radio
Switch/timer control = motors with the designation RMxxMx
Radio = motors with the designation RMxxMxF (the F here stands for radio)
Select the appropriate power by measuring the shutter area. For the calculations we assume a PVC or aluminum roller shutter with a profile weight of approx. 4.5kg/m².
up to 3,5m² = 10Nm
up to 6,5m² = 20Nm
up to 10m² = 30Nm
