The present invention provides a reel pipe motor, comprising a casing; a motor and a speed reduction assembly disposed within the casing; an L-shape motor end head having a tubular part and a box part which could be connected with the casing; a switch box disposed on the outer surface of the box part, in which a switch control panel and a bead switch are located; and a power supply plug and a hollow rod. The bead switch is connected with the hollow rod. The bead switch could be operated by pulling the hollow rod. A first end of the power supply plug is electrically connected with the switch control panel, and a second end thereof extends into the hollow rod and is electrically connected with an external power supply. The external and internal power lines both hide within the casing, which provides an aesthetic appearance of the motor as a whole. The operation of the motor is controlled by the bead switch, which provides more convenient use. This invention further discloses a rolling curtain positioning control system comprising the said reel pipe motor.
