Common motor types for automatic doors: brushless motor or brushed motor.
Automatic doors usually prefer to use brushless motors because they have advantages such as high efficiency, low maintenance, and long lifespan, which can better meet the operational needs of automatic doors.
As a common facility in modern architecture, automatic doors are receiving increasing attention for their convenience and intelligence. As the core component of automatic doors, the performance of motors directly affects the effectiveness of their use. So, do automatic doors usually use brushless motors or brushed motors?
1、 The difference between brushless motor and brushed motor
There are significant structural differences between brushless motors and brushed motors. Brushed motors change the direction of current through the contact between carbon brushes and commutators, thereby achieving rotor rotation. Brushless motors, on the other hand, use electronic commutation technology to precisely control the direction of current and rotor position through a controller, without the need for carbon brushes and commutators.
2、 Application of motors in automatic doors
In the application of automatic doors, brushless motors are favored due to their high efficiency, low noise, and long lifespan. Firstly, brushless motors have high energy conversion efficiency, which means that they can provide greater power output at the same energy consumption, ensuring the smooth operation of automatic doors. Secondly, the noise and vibration during the operation of the brushless motor are relatively small, which helps to improve the comfort of using the automatic door. Finally, the lifespan of brushless motors is usually longer than that of brushed motors, reducing the frequency of maintenance and replacement and lowering the overall cost of ownership for automatic doors.
However, brushed motors still have practical value in certain specific situations. For example, in some scenarios where cost requirements are extremely strict, brushed motors are competitive due to their lower prices. In addition, the structure of brushed motors is relatively simple, and maintenance and replacement are also relatively convenient.
3、 The development trend of automatic door motors
With the advancement of technology and the increasing demand for intelligence, automatic door motors are developing towards higher efficiency, intelligence, and environmental friendliness. Brushless motors, with their many advantages, will be increasingly widely used in the field of automatic doors. Meanwhile, with the continuous emergence of new materials and technologies, the performance of automatic door motors will be further improved in the future.
In summary, automatic doors usually prefer to use brushless motors. However, in practical applications, it is necessary to choose the appropriate motor type based on specific needs and scenarios.
