Somfy and Lutron both offer tubular motors for raising and lowering interior motorized shutters. Lutron sells the motor and shade together while Somfy sells only the motor which may be coupled with any window shade. Both companies also sell controls (wall switches, remotes and interfaces) that are utilized to operate their particular motors.
Within the late 90’s, Lutron introduced the QED (Quiet Electronic Drive) so it combined with its very own make of shades (roller shades mostly). The merchandise made big waves to be practically noiseless. It was a vintage illustration of redefining the parameters of competition within an industry. Beforethe creation of Lutron’s quiet motors, consumers didn’t know that motor noise level was or would be a element in their motorized shade purchase decisions. Only within the last few years has Somfy caught to the QED’s noiselessness. Today, there’s still a positive change, but it’s slight and many consumers don’t contemplate it a deciding factor.
Somfy manufactures two various kinds of ‘quiet’ motors utilized in motorized shutters an AC powered version (ST50) along with a more lately introduced Electricity powered version (ST30). Lutron’s QED Motors are low current, Electricity Motors. The main difference between AC and Electricity power would be that the former is high current as the latter is low current. AC Power is equivalent to the ability caused by plugging an electric cord right into a standard wall plug. Low current is operated by that very same outlet however the cord includes a transformer (consider a mobile phone cord or perhaps a computer cord using their boxes around the plug on in the center of an electric cord – that’s a transformer) and reducing or ‘knocking down’ our prime current power caused by the opening to low current power. A primary reason why Electricity power is essential is the fact that less building code issues arise with no electrician is needed for wiring low current powered motorized shutters. Absent an electrical contractor, wiring costs and job complexity are generally significantly reduced.
The QED will come in three various sizes known as the QED64, QED100 and QED225. The amount provides a rough gauge from the sq footage of material the motor is made to lift. For instance, the QED64 can lift a shade as much as 8 ft x 8 ft, the QED100 can lift a shade as much as 10 ft x 10 ft and also the QED225 can lift a shade as much as 15′ x 15′ – this size motor is just hardly ever needed for residential applications. They are approximations only, within the field, these motors are recognized to really lift greater than these number values imply. How big the motor affects its diameter which determines the diameter from the tube the motor uses. Lutron’s QED64 utilizes a 1 5/8″ tube, the 100 utilizes a 2 ½” tube and also the bigger 225 utilizes a 3 1/2″ tube. Tube diameter is essential mostly for figuring out how wide motorized shades could be without bending (deflection). A bent tube implies that fabric won’t roll-up correctly. The material will sag causing creases- this isn’t acceptable. Therefore motor dimensions are just as much about shade width because it is about lifting capacity.
Somfy’s quiet motors, referred to as Sonnesse line, also employ different tube sizes. The ST30 utilizes a 1 1/2″ tube, the ST50 may use whether 2″ or 2 1/2″ tube*. The lifting capacity from the ST50 falls approximately the 100 and 225. For large applications, Somfy has bigger motors, but up to now, they aren’t within the Sonnesse (quiet) products. It’s very rare that the motor bigger than an ST50 is required for interior applications. This is correct even when multiple shades are impelled with a single motor.
