A Hall-type run-length limited self-resetting coding device for a garage gate machine comprises a nylon turbine (5), a driving motor (1) for driving the nylon turbine (5) to rotate, a motor rotation counting limit mechanism for carrying out rotation counting limit on a rotor shaft of the driving motor (1), and a turbine counting calibration mechanism for calibration of the driving motor's (1) limited run-time. The turbine counting calibration mechanism comprises a turbine magnet (4) arranged on the nylon turbine (5) and a turbine position Hall element (9) adapted to the turbine magnet (4). The device is compact in structure and can effectively limit the limit deviation of a garage gate. |
