Most of the automatic doors produced by customers are used in office buildings, and the noise requirements for motors are higher than those of ordinary automatic door motors. We negotiate with customers and develop different sound-absorbing materials in-house to ensure that the motor noise can meet customer requirements

The noise of the brushed DC motor mainly comes from: The friction sound of the carbon brush of the DC motor and the commutator will produce noise. In this regard, the finish turning of DC motors is a very important process. Secondly, the bearing sound of the DC motor will also produce noise. Therefore, good quality bearings are also necessary.

For the customer's size, we conduct research and development with the production department and the R&D department according to the customer's requirements, and finally ensure that the motor can be fully installed and run stably in the small space reserved by the customer
