Direct Drive Motors- are used in conjunction with roller tracks as part of a direct drive system. The motor attaches to the end of the track where a shaft on the motor fits into a pulley, which moves the cable and operates the track components. Available as a straight or curved system, with the operating cable strung on the inside of the track. The motor is flush with the front edge of all tracks. All direct drive drapery motors are Smart Motors, designed with electronic sensor limit switches, thereby eliminating installation adjustment. All motors are available with surface mount or recessed low voltage switches; home automation systems, or with infrared or radio frequency wireless remote control. Drapery should be manufactured with a 3.5" return to cover motor projection and a 5" space between the last two pleats on return (stack) side.
