330 Nm Heavy-Duty Tubular Motor
The SOMMER S 330/8/92 NHK produces 330 Nm of rated torque, making it suitable for medium-to-heavy rolling shutter automation where a smaller tubular motor does not provide sufficient torque.
Motor selection should be based on more than shutter weight alone. The shutter curtain material, barrel diameter, shutter height, guide condition, friction and mechanical balance all affect the actual torque required.
92 mm Tubular Motor
The motor has a nominal diameter of 92 mm and is designed for installation inside a compatible rolling shutter barrel or tube.
This internal mounting design keeps the automation compact and avoids the large external footprint required by some side-mounted rolling shutter motors.
8 RPM Rolling Shutter Motor
The exact S 330/8/92 NHK model operates at 8 revolutions per minute. This is the correct SOMMER manufacturer specification for this model.
The actual shutter opening and closing speed depends on the roller barrel diameter and total shutter travel. A larger barrel circumference moves more curtain per motor revolution than a smaller barrel.
230V AC Single-Phase Motor
The SOMMER S 330/8/92 NHK operates from a 230V AC, 50 Hz single-phase power supply. This makes it suitable for many commercial and industrial shutter installations using standard mains power.
Electrical installation should include the correct isolator, protection devices, control equipment and wiring according to the motor and site requirements.
4-Minute Short-Time Duty
SOMMER specifies a permitted short-time operating duration of 4 minutes for the S 330/8/92 NHK.
This motor is intended for normal shutter opening and closing cycles rather than continuous-running industrial machinery. Repeated operation without adequate cooling can activate thermal protection or reduce motor life.
Emergency Hand Crank – NHK
The NHK version provides a manual emergency hand-crank system. If mains power is unavailable, the shutter can be operated manually using the supplied crank mechanism.
This feature is especially useful for commercial shops, warehouses, factories and garage shutters where emergency access may still be required during a power failure.
IP44 Protection
The SOMMER tubular motor has an IP44 protection rating. The installation should still protect the motor and electrical components from direct water exposure and unsuitable environmental conditions.
Correct cable routing, electrical isolation and shutter enclosure design are important for reliable long-term operation.
Suitable for Shutters Up to Approximately 350 KG
Your SOMMER S 330/8/92 NHK configuration is commonly specified for compatible rolling shutters weighing up to approximately 350 kg.
This should be treated as an application guideline rather than an absolute rating for every shutter. The actual permissible curtain weight depends on the roller diameter, shutter dimensions, curtain construction, bearings, guides and mechanical resistance.

Replacement SOMMER Tubular Motor
The S 330/8/92 NHK can also be considered as a replacement for a compatible existing rolling shutter tubular motor.
Before replacement, confirm the existing motor torque, motor diameter, speed, voltage, roller tube dimensions, drive adapter, crown arrangement and emergency manual override system.
Professional SOMMER Tubular Motor Installation
Professional installation is recommended because a tubular shutter motor must be correctly fitted inside the roller tube and aligned with the shutter shaft.
The installer should also inspect the curtain, guide rails, bearings, barrel, mounting brackets, electrical wiring and manual emergency mechanism before commissioning the shutter.
