    (54) Reducing motor for the elevation of blinds and awnings


    (57) The reducing motor forms an operating unit which includes a general air tight frame (1), inside which a DC motor (3) is installed. At the outlet of this reducing motor there is a first reducing pitch (4,5) with turn reduction, made up of a series of connections. The last one of these connections is installed at the end of a spiral conveyor (6) connected to an outlet crown (7), and acts as a second reducing pitch and as increaser of the outlet torque. The unit also includes a programming disk (9) to memorize the limits of ends of travel of the outlet axle, to rotate in either direction the winding/unwinding tube of the blind or awning to which the said unit is attached, so that this unit is placed on the outside.
