Before installing and debugging, the speed reducer motor must be checked before it can be installed. In the process of installation, the deceleration motor should be protected from impact. When the structural parts are installed on the shaft of the decelerator, it is not allowed to knock or press directly on the shaft of the decelerator. The arrangement of wires needs to be straightened and not bent. This will affect the internal defects of the motor. Do not force the reducer at the end of the output shaft, otherwise the gear will be damaged. When the transmission structure is fixed with a binder on the shaft of the reducer, the bearing of the reducer can not be attached. When installing the circular gear reducer motor and planetary reducer motor, it is necessary to control the length of the installation screws. Screwing in too long will damage the structure inside the reducer. Before installing the motor, it is necessary to check whether the rotating system driven by the motor is faulty or not. Otherwise, when the motor is energized, it will block the rotation, which may damage the gear of the reducer.
