Aوتوماتيكي الباب المحرك
A compact brushless DC gearmotor assembly that converts controlled low-voltage drive into quiet timing-belt motion for an overhead automatic sliding cleanroom door operator.
- Single Brushless DC Motor
- Integrated Reduction Gearbox
- Toothed Belt-Drive Pulley
- Keyed Five-Wire Connection
مقدمة المنتج
This automatic door motor is a replaceable mechanical drive module for overhead pedestrian sliding-door operators. One black cylindrical brushless motor is coupled to a silver die-cast reduction gearbox, which delivers usable door-driving torque through a single toothed timing pulley. The zinc-plated L bracket provides four fixed mounting points, while the terminated cable harness carries the motor and feedback conductors to the separate operator controller. The assembly contains no door logic board, sensor or mains power supply, keeping motor replacement distinct from controller service.
الخصائص الرئيسية
A compact right-angle reduction stage lowers output speed and increases pulley torque without extending the drive assembly along the operator rail.
The black toothed pulley provides positive engagement with the operator timing belt and reduces slip during reversing movement.
A keyed low-voltage harness and four-hole galvanized bracket provide repeatable electrical orientation and rigid mechanical location during replacement.
مخاوف المنتج للعملاء
A replacement door motor must match the operator's electrical feedback, pulley geometry, reduction ratio and mounting datum; similar-looking generic motors are not automatically interchangeable.
An incompatible pulley pitch or tooth count can produce belt noise, lost motion or premature tooth wear.The single toothed output pulley is selected against the existing operator belt profile and aligned on the original drive plane.
A motor with the wrong feedback conductors may run unpredictably or fail to report position to the door controller.The keyed five-wire harness is matched by pin function and supply requirements before it is connected to the existing control module.
Bracket distortion or shifted hole positions can misalign the motor and overload the reduction bearings.The rigid four-hole L bracket locates the gearmotor at a repeatable height and keeps the output shaft square to the belt path.
Replacing the motor cannot correct controller, sensor or door-track faults that impose excessive load.Drive current, carriage movement, belt condition and controller commands are checked separately so the motor module addresses the actual failed function.
