In today's fast-paced world, automatic doors have become an essential feature of modern buildings. They are a crucial component of both residential and commercial spaces, offering convenience, accessibility, and enhanced security.

Behind each, the automatic door motor works with other components to make the automatic door function. In this article, Power Motor will focus on different automatic electric doors and electric motors for them. After reading this page, you will know all about this topic!

What Are Automatic Doors?

Automatic doors are mechanical doors that open or close automatically without the need for manual operation. They facilitate convenience for people who are occupied with their hands or those who have accessibility issues. By opening the door only when necessary, automatic electric doors also help save air conditioner energy. Plus, they help ensure hygiene by eliminating human touch.

Then, how do automatic doors work? Typically, there are the following main components of automatic doors:

l Sensor System: It detects motion (the motion sensor), presence (the infrared sensor), or force change (the pressure sensor) and triggers the opening of a door.

l Control System: It receives signals from the sensor and then activates the motor to open or close the door. It can be programmed to change factors like speed and time.

l Motor and Drive Mechanism: The automatic door motor provides the power to move the door. Meanwhile, the drive mechanism can come in different types, such as the belt drive system and the gear drive system.

Different Types of Automatic Doors

There are many types of automatic doors, each with their unique features suited for different scenarios. Below are some of the most common types:

l Automatic Sliding Doors

Sliding doors slide open to the sides when a person approaches. They are common at malls, airports, and other high-traffic areas. Their biggest advantage is that they don't take up much space in the doorway area.

l Automatic Swinging Doors

These doors open outward or inward like traditional hinged doors. They can be single-leaf or double-leaf, depending on the width of the doorway and the estimated traffic flow.

l Automatic Folding Doors

Folding doors consist of multiple panels that are hinged together. They fold and stack neatly to one side when fully open. This facilitates a large opening and is recommended for places where the opening space is of concern.

l Automatic Revolving Doors

Revolving doors are very common in high-traffic commercial areas. They consist of several door sections that rotate around a central shaft, which helps control the flow of people.

l Automatic Overhead Doors

Overhead doors are designed to open upwards and then fold horizontally along tracks mounted above the door opening. The roll-up door motor, or garage door electric motor (as the overhead door can be commonly seen in the garage), is responsible for the lift movement.

Each automatic door, of course, has different specifications and requirements on motors to keep their operations reliable and smooth.

Different Automatic Door Motors

Automatic door motors may be broadly classified into AC motors and DC motors.

l AC Motors

AC automatic door motors are commonly applied to bigger and high-duty cycle automatic doors, such as those found in commercial or industrial places. While delivering power performance, they can be bulkier and noisier than DC motors. They are ideal for automatic doors requiring high power output and consistent performance.

l DC Motors

DC door motors are typically used in automatic doors that are low-power or battery-powered. They are energy-efficient and offer smooth and easy control. Generally, they find a wide application in residential buildings, hospitals, office spaces, garages, and more.

Comparatively, DC automatic door motors are gaining increasing popularity in the market, and that's why Power Motor put much effort into developing high-power automatic door DC motor solutions. By optimizing the structural design, we offer reliable electric doors that offer easy control, high output torque, and steady and reliable performance.

How to Choose the Right Automatic Door Motors

As automatic door motors can come with different specs, you can make the best choice by considering the following factors.

l Power Requirements: The motor must be powerful enough to hold the weight and size of the door. Larger doors, such as overhead or sliding doors, require more powerful motors.

l Speed and Torque: The motor must be capable of providing the necessary speed and torque to ensure smooth and timely operation. For instance, high-traffic areas may require faster-opening doors, while quieter spaces might prioritize slower, smoother motions.

l Efficiency: An efficient motor will consume less power and have lower operating costs. DC motors comparatively do a better job, making them ideal for energy-conscious installations.

l Durability: Since automatic doors are used frequently, the motor needs to be tough and resistant to wear and tear. Look out for motors that have long operation lives and handle heavy-duty cycles.

l Noise Level: Noise may be a real concern, particularly in quiet areas such as offices or hospitals. DC motors, in general, are quieter in operation compared to AC motors.

l Cost: Although the cost of high-quality motors is generally higher, using them will yield great benefits in the long run due to savings in maintenance and energy consumption.
