Tubular Motors
Tubular motors are placed inside the shaft tube. The space loss is less than industrial motors. The head of the engine is narrower than the engine itself. The engine can be easily operated manually with the crank handle. At the same time, these motors can be used on doors heavier than 350 kg or wider than 30 m2. Not suitable for frequently used doors.
• Wide range of torque options from 150 Nm to 330 Nm
• Narrow engine head requiring minimal space for the engine
• Possibility of manual operation in power cuts
• Not suitable for frequent use.
Shaft for Tube Motors, Industrial Motors and Chain Drive Motors
The diameter of the pipe is calculated according to the width and weight of the shutter to ensure the correct deflection. EN 10220 allows a maximum bending of 1/500, which means that at a width of 5,000 mm, the deflection of the pipe (as measured at the maximum bending point) should be 10 m (1/500) or 12.5 mm (1/400).
CNC laser cut edges and hexagonal spindles fit the tube perfectly. Especially the hexagonal shafts increase the resistance of the shutter against the horizontal forces that may come from under it.
