A rolling shutter curtain that outgrows a 60 Nm motor needs a larger frame, and Somfy builds the DMI6Hz for that load. Somfy publishes 100 Nm of torque at 14 rpm under reference 2007156, which converts to about 885 in-lb. The radio receiver sits inside the motor head. The cable ends in a factory NEMA plug, so the electrician does not need to land wires in a junction box to bring the motor up.
Start with the torque number
Torque governs this purchase. Fabricators take the finished weight of the shutter curtain or the awning fabric and hardware, multiply by the radius of the drive wheel, then add margin for friction in the guides and for a cold morning. The result lands on a motor size. At 100 Nm the DMI6Hz sits at the top of the Somfy DMI range, above the 50 Nm and 80 Nm frames that cover most residential closures.
Speed matters second. Somfy rates the 2007156 at 14 rpm, a deliberate pace for a heavy curtain. A slow motor moves a large mass without slamming the bottom bar into the sill, and it holds the load under control on the way up. Installers who want a faster cycle on a light screen should size down the family rather than reach for this motor.
One more number belongs in the sizing conversation. Somfy prints the model code as DMI6HZ 100/14 120/60 C6M PLUG SJTW18, and that string carries the torque, the speed, the supply, and the cable type in order. Read it off the motor label when you receive the unit and confirm it against the order.
Somfy names two applications on its own product page: awning and rolling shutter. That pairing tells you the design intent. Both are exterior products that carry real weight, both run in guides or arms that add friction, and both ask a motor to work through weather rather than in a conditioned room.
Large commercial rolling shutters over storefronts and loading bays fall inside this range. Wide projection awnings on a heavy cassette do as well. A quiet interior roller shade does not belong on a 100 Nm motor, and Somfy builds the Sonesse family for that side of the catalog.

Somfy does not publish a minimum tube inner diameter, a sound level, or an operating temperature range for this reference. Treat any figure you find for those on a third party listing as unverified and confirm the tube fit with your crown and drive supplier.
Radio control without an external receiver
The Hz receiver lives in the motor head. You pair a Somfy or Simu Hz transmitter to the motor and the shutter answers, with no receiver box to mount and no control wiring to pull back to a switch location. On a retrofit that saves the conduit run, and on a new build it keeps the wall free of a low voltage home run.
Somfy publishes the radio frequency as 433.420 MHz and the open field range as 492.15 ft. Open field means clear line of sight. Masonry, metal shutter boxes, and steel framing cut that number down, so plan transmitter positions with the building in mind. Set limits and pair transmitters before the curtain goes on the tube, while you can still reach the motor head.
Brackets and mounting plates
The motor head needs a plate that matches the shutter box or the awning bracket you already have. Two DMI plates cover most of what installers meet in the field.
- Simu DMI Bracket, 1-Piece Round Adjustable Cast Plate (9420647) suits a round mounting position and gives you adjustment on the plate itself, which helps when the box was framed before the motor arrived.
- Simu DMI Motor Bracket Plate, 100mm x 100mm (9706034) drops into the square 100mm pattern that shutter box makers cut as a standard opening.
Measure the existing plate opening and the head profile before you order. The crown and drive stay a separate decision, because they follow the tube profile rather than the motor. Bring the tube type and the outside diameter to your supplier and match the set to the tube in hand.
Power draw, plug, and protection rating
At 430 W in operation the DMI6Hz asks for a real circuit. Count the motors on a bank of shutters, add the draw, and check the breaker before anyone plugs in. Standby sits at 0.34 W, low enough that a wall of motors adds little to the idle load of the building.
The NEMA plug shortens the electrical work. An outlet inside the shutter box or above the awning cassette turns commissioning into a plug-in step, and it gives the service technician a disconnect for later. Somfy rates the motor IP 44, which covers splashing water from any direction. Mount it under the cassette hood or inside the shutter box rather than in the open weather, and keep the plug connection out of standing water.
On a heavy rolling shutter with a fall risk, a fabricator may specify a mechanical brake in the assembly. The Simu Safety Brake, 404 Nm (2005627) covers that requirement on Simu DMI assemblies. Confirm the brake specification with the shutter fabricator for your closure rather than adding one by default.
Order the Somfy DMI6Hz 100Nm 14rpm 120V with NEMA plug (2007156) once you have the torque calculation and the plate pattern settled. Add the bracket plate that matches your box in the same order, then bring the tube profile to your crown and drive supplier. Somfy backs the motor with a 5 year warranty and a UL approval, and the Hz receiver inside the head keeps the control side down to a transmitter and a pairing sequence.
Frequently asked questions
What tube size does the Somfy DMI6Hz 100 Nm fit?
Somfy does not publish a minimum tube inner diameter for reference 2007156. The motor takes DMI6 class crowns and drives, and the crown and drive set decides the tube fit rather than the motor body. Measure the tube profile and the inside diameter, then match a set to it with your supplier before you order.
Does the DMI6Hz need an external radio receiver?
No. Somfy builds the Hz receiver into the motor head, so a Somfy or Simu Hz transmitter talks to the motor with no receiver box in the circuit. Somfy publishes the radio frequency as 433.420 MHz and the open field range as 492.15 ft. Building materials reduce that range in practice.
How much power does the DMI6Hz draw?
Somfy publishes 430 W during operation and 0.34 W in standby, on a 120V 60 Hz supply. Total the operating draw across every motor on a shared circuit and compare it against the breaker rating. The factory NEMA plug lets an electrician feed the motor from an outlet inside the shutter box or awning cassette.
Can the DMI6Hz mount outdoors?
Somfy rates the motor IP 44 and lists awning and rolling shutter as its applications, both exterior products. IP 44 covers splashing water from any direction, not immersion or pressure washing. Mount the motor inside the shutter box or under the awning cassette hood, and keep the plug connection clear of standing water.
