More Information
Summary:Small permanent magnets are affixed to the protruding portion of a rotor of a motor that is coupled to gears in a gear enclosure. The rod of a window covering, is coupled to the gears such that when the motor is energized by a user command signal, the window covering moves. Small braking magnets are also affixed to the receptacle of the gear enclosure, such that when the motor is deenergized, the magnetic coupli ng between the magnets of the rotor and those of the gear enclosure brakes the rod from turning under the weight of the window covering.
