Torque sets the shortlist before anything else
An 80 Nm tubular motor belongs on a tube that already carries real weight. The Somfy Simu DMI6Hz 80Nm 14rpm 120V with NEMA Plug (2007146) sits near the top of the Simu T6 DMI Hz line, one step under the 100 Nm version. Installers reach for it when a wide retractable awning or a tall rolling shutter asks for more holding power than a 60 Nm motor gives. Somfy publishes 80 Nm at 14 rpm for this reference on 120V 60Hz power, inside a 108 to 126 V window.
Torque alone does not finish the sizing work. Your tube has to clear a 2.36 in minimum inside diameter, and the motor body measures 2.28 in across. Measure the tube first. A fabric roll that fits an LS40 or LT50 tube will not take this motor, because the 60 series body needs the larger barrel.
Somfy lists two applications for 2007146: awning and rolling shutter. The 14 rpm speed reads as deliberate on a long drop, which matters on a shutter curtain that you want to watch seat into its guides. On a cassette or folding-arm awning, the same speed keeps the arms from snapping open.

Tube, crown and drive fit
Every tubular motor needs two adapters inside the barrel. The crown locks the motor head to the tube so the body cannot spin, and the drive wheel transmits rotation into the tube wall. Both parts match a tube profile, so the profile you own picks the parts, not the motor.
Two combinations cover most 60 series work on this motor. A 70 mm octagonal tube takes the Somfy T5/T6 70mm Octagonal Aluminum Drive (9011878), the standard European shutter profile that shows up on imported roller shutter kits across North America. An 85 mm round Simbac tube takes the Somfy Simu T6 85mm Round Simbac Tube Crown (9690085), which suits the bigger awning rollers where fabric bulk forces a wide barrel.
Order the crown and the drive as a pair for whichever profile you have. A drive without its matching crown leaves the motor head unsupported, and the motor will chew its own mount.
Brackets and the override shaft
The DMI head carries a round mounting face, so it wants a DMI bracket rather than an LT50 or LS40 plate. The Somfy Simu DMI Bracket 1-Piece Round Adjustable Cast Plate (9420647) seats the motor head and gives horizontal and vertical adjustment during hang, which saves a reinstall when the headbox opening sits off center.
The CMO head is the reason many dealers pick this motor over a plain radio version. CMO stands for crank manual override, so a 7 mm hex shaft drops into the head and an operator winds the awning in by hand when the power goes out. Somfy built that override into the motor casting rather than into an add-on gearbox. Storm season on a coastal patio makes the feature worth the price difference on its own.
The crank side needs its own part. The Somfy Simu Extension Shaft 7mm Hex L=330mm with Screw (9420659) reaches from the CMO head out through the headbox wall to a crank eye, so a homeowner can wind the awning in without a ladder. Specify the shaft length against your headbox depth before you cut anything. Check the hex socket on the motor you receive against the shaft you order.
Simu Hz radio control
This motor carries a Simu Hz receiver on 433.420 MHz, with a 492.15 ft open field range that Somfy publishes for the reference. Masonry and metal headboxes shorten that number in practice, so plan on a fraction of it through two walls. The receiver draws 0.34 W at rest, which keeps a bank of motors off a panel's standby budget.
Pairing runs through a Simu Hz transmitter rather than an RTS remote. Simu Hz and Somfy RTS both sit on 433.42 MHz, and they use different protocols, so an RTS remote will not drive this motor. Match the transmitter to the Hz platform. Call us before you order a control if you are not certain which platform your existing remotes use, because the motor label and the remote label both name the technology.
Install notes installers ask about
Limits on this motor are mechanical, set with the two adjustment buttons on the head, and the mechanism holds 28 turns of tube rotation. Count the turns your drop needs before you commit the headbox. A 28 turn ceiling on a 70 mm tube covers a tall shutter, and a long drop on a small tube can run past it.
Power comes in through a 19.69 ft SJTW cord that ends in a NEMA plug, so the install takes a receptacle rather than a junction box and a licensed splice. That cord length reaches a long way across a patio ceiling. Keep the plug end out of standing water, since the IP 44 rating covers splash and not immersion.
Somfy builds in 5 minute thermal protection. A motor that trips after repeated cycling needs about 20 minutes to cool, and it returns to service on its own. The operating range runs from -4 F to 140 F, which carries a south facing awning through a Phoenix summer and a shutter through a Minnesota winter.
The Somfy Simu DMI6Hz 80Nm 14rpm 120V with NEMA Plug (2007146) answers one job well: a heavy awning or shutter that wants wireless control and a hand crank backup on the same motor. Somfy's 5 year warranty and the UL listing stand behind it. Add the DMI bracket, the crown and drive set for your tube profile and the extension shaft, and the kit is complete before the motor ships.
Frequently asked questions
What tube does the Simu DMI6Hz 80Nm motor fit?
Somfy publishes a 2.36 in minimum inside diameter for reference 2007146, and the motor body measures 2.28 in. In practice that means a 60 series tube: a 70 mm octagonal shutter profile or an 85 mm round Simbac awning tube. Order the crown and drive wheel that match your tube profile.
How much torque does the DMI6Hz 80Nm deliver?
Somfy rates it at 80 Nm at 14 rpm on 120V 60Hz power, drawing 3.4 A and 390 W during operation. The 80 Nm figure sits between the 60 Nm and 100 Nm versions of the same DMI6Hz platform, so a tube that overloads the 60 Nm motor often lands here.
Can I use a Somfy RTS remote with this motor?
No. This motor carries a Simu Hz receiver, and Hz and RTS run different protocols even though both sit on 433.42 MHz. Pair it with a Simu Hz transmitter. Check the technology printed on your existing remote before you order a control for this motor.
Does the manual override need a separate part?
Yes. The CMO head accepts a 7 mm hex shaft, and the Somfy Simu Extension Shaft 7mm Hex L=330mm with Screw (9420659) carries the drive from the head through the headbox to a crank eye. Measure your headbox depth and the run to the crank position, then confirm the hex socket on the motor you receive.
