Selecting the correct tubular motor is not only about power-it is about matching the motor to the real working conditions.
Key Selection Parameters
Curtain or Shutter Weight
Tube Diameter (38mm / 40mm / 60mm / 70mm)
Required Torque (Nm)
Operating Voltage (AC or DC)
Control Method (Switch / Remote / Smart System)
Common Selection Mistakes
Choosing torque based on tube size only
Ignoring friction from side rails
Overlooking duty cycle limitations
A properly selected tubular motor improves reliability, reduces noise, and extends service life.
