Automatic Door

Automatic doors are the result of developing and improving the functionality of doors according to people's needs. Automatic doors not only beautify the entrance and exit environment and improve transportation convenience, but also have various additional functions such as environmental protection, energy conservation, safety, and hygiene. They are very suitable for hotels, clubs, office buildings, and various exhibition halls. So far, most living places have used automatic doors, and their applications are also more widespread.

Mr. Barp from Brazil approached us and stated that they need a more energy-efficient and quieter motor for use on automatic doors in office buildings. Therefore, the noise requirement for the motor is higher than that of ordinary automatic door motors, preferably below 45dB and not too large, otherwise it will affect the flow of people. 24V 60W 750rpm DC brushless motor with 12ppr encoder, suitable motor horsepower, reducing energy consumption. The most important thing is to hope that the lifespan of the motor is as long as possible, and the number of working cycles of the motor is required to be no less than 1 million times.

Generally speaking, the noise of DC brushless motors mainly comes from two aspects:

First,The friction sound between the carbon brush and the commutator of a DC motor can produce noise. In this regard, precision turning of DC motors is a very important process.

Second ,The bearing sound of a DC motor can also cause noise. Therefore, high-quality bearings are also necessary.

People usually ask what is the horsepower of the automatic door motor, how big or how many doors can this door open? People habitually believe that the larger the door opener, the stronger it becomes. This is unscientific and will result in electricity waste. We need to choose the appropriate motor rules to help customers reduce costs.

In addition, the material and manufacturing process of the motor shaft, shaft sleeve, rotor support structure, and gearbox jointly determine the lifespan of the motor, requiring professional and appropriate assembly.

After understanding the weight and motor capacity of the customer's automatic door design, we recommend a motor with appropriate horsepower and size to the customer. The subsequent customer received the motor and after a month of testing, he was very satisfied with our motor. The power of the motor is more suitable than the motor previously used by the customer. The noise also meets customer expectations. After 4 months of trial orders, large-scale procurement will begin.

"Best wishes to your company! You have been of great help to us. This proves that you are a very professional motor manufacturer. We are pleased to find you as our motor supplier." This is sincere feedback from Mr. Barp (Chief Engineer).
