Gate motors are unique electrical motors created to open and close numerous access points around buildings, homes, and offices. Gate motors tend to be installed for security. However, these types of electric motors are also utilised for automatic gates, like the ones seen in parking lots, as well as other areas that would benefit from having an automatic gateway.
Gate motors are different from other motors because their usage is restricted to only opening and closing a set of gates or doors. Have you ever driven your car straight through a toll booth and had to pay? Then you have first had an experience of a simple example of a gate motor in action.
Gate motors can be highly advantageous when used in the right circumstances. This article will examine precisely what a gate motor is and how they work. We will also explore the significant categories and some essential benefits you can expect when installing a gate motor. We will also provide a few pointers on choosing a suitable motor. Regarding gate motors, we at Glow Innovations are passionate about giving you the right product. So if this article interests you, be sure to contact us and let one of our helpful staff get you what you need when you need it.
What Are Gate Motors?
Gate motors are electrical motors specifically designed to open and close gates. Motors, along with the gates they power, are generally used to improve the security of a property, whether residential or commercial. For example, controlling exits and entrances to a building. Automatic parking gates are one of the most popular usages for these gate motors. The gates are found in huge parking lots and factories where an automatic gate is beneficial because it can save time and human resources needed.
The automation of gates depends on which two categories the motor falls into, Gear Drive or Direct Drive. Gear Drive motors utilise a gearbox to drive the shaft connected to the gate. Direct Drive motors typically use a worm gear motor or a ball screw to directly drive a post connected to the gate.
How Do Gate Motors Work?
Gate motors work by receiving signals from a controller instructing the motor on what to do. Because gates are generally either opened or closed, matching that to an on or off position in the circuit allows for a single switch to control the gate’s manoeuvrability. Although these are the theoretical basics, you can control gate motors using various systems that allow for the gate’s automation.
Because gate motors open and close electric gates, the engines must be connected to a general power source. However, this is generally the property’s main power line. Today with the innovation in renewable energy sources, it is even possible for some gate motors to be powered by solar power. It is also essential to note that most motorised gate systems come with a battery, which will charge when connected to a power source, allowing the gates to operate when power is cut off.
Another crucial element is the motor’s switch, which is either a remote control or wired to a sensor. The switches generally have three settings: open, close, and stop.
When you see that the switch is turned to the “open” position, know that the motor will rotate counterclockwise. As it is rotating in this direction, the gate should open. And when the switch is turned to the “closed” position, all motion in the motor will be stopped immediately. This way, the gate should not open or close even if the switch is accidentally turned to the “open” or “close” position.
Some systems can use software run on computers to operate the gate motor. However, this level of control is usually recommended for larger, more industrial applications. These systems tend to be connected to a central control panel, often overseen by the security team. A significant benefit of computerised systems is that they are cost-effective and can often be linked to other security systems, for example, a company’s alarm system.
Types Of Gate Motors Used In Gate Automation
So many different types of automatic gate motors are available for gate automation. Here are three of the most popular system types.
AC Gate Motors
AC motors are some of the most popular systems in gate automation because they are versatile and affordable. These motors can also be used both indoors and outdoors. One key characteristic of a custom AC motor is that, as the abbreviation “AC” suggests, they function on an alternating current.
There are more differentiating characteristics, but understanding the current is critical for better understanding the system as a whole. An AC charge flows in one direction around a circuit, but the current direction is reversible. This means that changing the direction of the current is determined by the voltage on the AC circuit. In contrast, the DC motor current will only flow on the way around the circuit. This is why the voltage on a DC motor tends to remain constant.
The current found within custom AC motors relies on a device known as an alternator, which is responsible for alternating the direction of the current. An alternator is a simple electrical generator in which an electromagnetic field (EMF) is created whenever electricity passes through a spinning rotor shaft. On its own, the roto revolves within a static wire coil called a stator, causing the EMF to change direction as the rotor shaft rotates relative to the stator.
DC Gate Motors
Because of their low price, DC motors are typically utilised in low-end gate automation systems. Or smaller systems like those found in residential security systems. Similarly to the AC motor, these motors can also be used either indoors or outdoors.
Like most equipment operated through gears, the gear is connected to the engine, and the amount of shaft rotations calculates the speed of this made every minute. In many situations, the DC gearhead motor, as well as the rotator shaft, are connected. The rate at which the rotator moves can be decreased through a gearbox with the outcome of increased torque. This is basically how much force or power the motor rotator has.
How efficient the gearbox is usually dependent on what type of gear configuration has been established. One central element of the design is the number of reduction stages or the number of gears that are in place. Despite this, numerous other factors, such as lubricants or ambient temperatures, can impact the generator’s efficiency.
Stepper Gate Motors
Stepper gate motors are extremely accurate motors usually utilised in heavy-duty setups. The best environment for these motors is when vibration can hinder the gate’s functioning properly. Because of their accuracy, stepper motors are regularly used with automatic gates when there is no room for errors. Compared to the previous system discussed, one of the main characteristics of stepper gates is that it rotates in steps instead of a continuous motion. Like any other electrical motor, a stepper motor still has one part (the rotor) which moves, and another (the stator) remains stationary.
Stepper gate motors are electric motors utilising two sets of interacting coils to create a rotating magnetic field. The electromagnetic fields within the coils interact with an external magnetic field, and a reciprocating motion is produced. This motion can be utilised for various purposes, including rotary and linear movement and force generation. Stepper gate motors are usually smaller than other electric motors and tend to be integrated within electronic elements.
Over the years, stepper motors have become increasingly popular in wearable technology and robotics applications. Additionally, it is commonly used in robotics. Stepper motors have also been seen for sewing machines, 3D printers, and other devices requiring precise movements. For example, they have been seen in the medical industry in medical equipment like hospital beds and wheelchairs to help facilitate precise movements.
Stepper gate motors have built-in coils that create north and south poles when energised. Once this has occurred, a push and pull will be made that causes the magnetised rotor to spin.
Benefits Of Using Gate Motors
Gate motors are practical investments due to the many benefits they provide. Firstly their convenience is one of the biggest draws. They can automatically open and close gateways whenever a sensor, such as a motion sensor, triggers them, so you will not have to manually climb out of your vehicle to open the gate.
Gateways which are operated by gate motors can also be used manually. This can be useful in situations where a sensor is not appropriate. Gate motors are also helpful in controlling the flow of traffic in parking lots.
Sensors trigger them and can be used manually. This can be very convenient for large parking lots that need a lot of traffic flow control. Gate motors can also be found in more industrial settings to control the flow of materials. Sensors also trigger them and can be operated manually. This can be very useful in manufacturing settings.
How To Choose The Correct Gate Motor
When deciding which gate motor to buy, you must ensure it matches your specific gate. You also need to provide enough power for it to function correctly. There are some factors which are essential for you to keep in mind when selecting which motor to buy.
Firstly, you need to consider what type of motor you want. Two types of motors are available for you to select from: DC and AC. AC motors tend to be more common. However, DC motors tend to be utilised in low-end applications. AC motors are more versatile, but both systems can operate comfortably inside and outside. Additionally, AC systems are more energy efficient than DC motors.
Another factor you should keep in mind when choosing an engine is the amperage and voltage of the motor. The amperage and voltage are significant as they dictate the motor’s energy. You must ensure that the gate motor you select is compatible with the amount of voltage your electrical box has. If they are not compatible, then it is suggested that you upgrade your electrical box.
Can Any Gate Be Automated?
The answer to this question is yes! You can automate any gate motor you have. Gate motors have been created to open and close a gate or a gateway. They have been designed to last for many years and are very reliable. They tend to be connected to sensors that trigger the gate to open or close.
