The core part of the door opener is the motor, and the quality of the motor plays a decisive role in the quality of the door opener. Therefore, the quality of the door opener also needs to be analyzed from its motor. However, the material and manufacturing process of the motor's reducer volute, bushing, worm gear, rotor support structure, and mounting seat determine the length of the motor's service life and the ability to resist bumps and shocks.
The waterproof performance of the door opener motor is also very important, and its waterproof performance is generally affected by the outlet and the sealing ring of the bottom cover. The motor outlet of the door opener with good waterproof performance is fully sealed, and has undergone special waterproof treatment, and the bottom cover sealing ring is made of oil-resistant rubber sealing ring, so everyone must pay attention to the comparison when purchasing the door opener.
