Disclosed is a run-length limited self-resetting type limit encoder, comprising a driving motor (13), a motor output shaft (12), a control circuit board (3) and a transformer (4); a worm wheel box of the driving motor is provided with a motor cover plate (5), a through-hole is provided in the middle of the motor cover plate, and the motor output shaft is mounted in the through-hole; a front end of the motor output shaft is connected to a photoelectric encoding mechanism; the photoelectric encoding mechanism, the driving motor and the transformer are all connected to the circuit control board; a signal is transmitted between the circuit control board and the photoelectric encoding mechanism, the driving motor and the transformer via a circuit; and the circuit control board is provided in an electric motor. The run-length limited self-resetting type limit encoder has a simple structural design, low production costs, is convenient to mount, is accurate in limitation and can reset automatically.
Description
technical field [0001] The invention relates to a limit mechanism of a door machine, in particular to a self-resetting limit encoder for running limit. Background technique [0002] Nylon Worm Gear Reduced Worm Gear Garage Door Motor is quiet, efficient and consistent. However, in the stopped state, when the output shaft adds a large torque, it will drive the worm to rotate, and the self-locking ability is poor. Using the conventional worm shaft Hall pulse cumulative counting limit method will cause the garage door machine to deviate from the limit and cannot be used. . [0003] The traditional method is to set a reference point 2 at the appropriate position of the track chain or synchronous belt that is always synchronized with the door body, and install a matching reference point switch 1 at the appropriate position of the motor (such as figure 1 shown). When the door stroke is set, the reference point pulse position and the limit count pulse maintain a certain pulse qu...
