What Is an Actuator?<\/strong><\/h2>\n

\"HOW<\/p>\n

Actuators are widely used in everything from everyday equipment\u2014such as automatic doors, industrial robots, and medical equipment\u2014to advanced machinery. However, some people may find it difficult to understand exactly what role they play and how they differ from motors.<\/p>\n

First, we\u2019ll explain the basic role of an actuator and how it differs from a motor, with which it is often confused.<\/p>\n

 <\/p>\n

Overview of Actuators<\/strong><\/h3>\n

An actuator is a drive device that converts energy\u2014such as electricity, pneumatic pressure, or hydraulic pressure\u2014into mechanical motion to operate machinery and equipment. It is designed to produce movements\u2014such as rotational, linear, or with a rotational angle\u2014tailored to specific applications.<\/p>\n

For example, they are used to open and close valves, operate automatic doors, and drive robot joints. In security doors, depending on the configuration\u2014such as electric locks or automatic opening\/closing mechanisms\u2014actuators generate the motion necessary for locking, unlocking, and opening or closing the door.<\/p>\n

In this way, actuators convert energy into motion tailored to the application, supporting the operation of machinery and equipment.<\/p>\n

 <\/p>\n

The Difference Between Actuators and Motors<\/strong><\/h3>\n

Although both actuators and motors<\/a> are used to move machinery and equipment, they serve different purposes. The main differences are as follows.<\/p>\n\n\n\n\n\n\n\n
\u00a0Comparison Criteria<\/strong><\/td>\nMotor<\/strong><\/td>\nActuator<\/strong><\/td>\n<\/tr>\n
Main Function<\/strong><\/td>\nGenerates power<\/td>\nGenerates motion according to the intended purpose<\/td>\n<\/tr>\n
\u00a0Basic Motion<\/strong><\/td>\n\u00a0Rotational motion<\/td>\nRotation, Linear Motion, etc.<\/td>\n<\/tr>\n
Components<\/strong><\/td>\nMotor Unit<\/td>\nMotors, gears, screws, etc.<\/td>\n<\/tr>\n
Role in Security Doors<\/strong><\/td>\nGenerates power<\/td>\nConverts power into the motion required for locking and unlocking<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

To use a security door as an example, the motor is the \u201ccomponent that generates force,\u201d while the actuator is the \u201cmechanism that converts that force into the motion required for locking and unlocking.\u201d In an electric actuator, the motor\u2019s rotation is converted\u2014via gears, screws, and other components\u2014into the linear motion of the locking mechanism (such as a deadbolt or latch), and by moving this locking mechanism, the door is locked or unlocked.<\/p>\n

 <\/p>\n

How Actuators Work<\/strong><\/h2>\n

\"HOW<\/p>\n

An actuator operates machinery and equipment by converting externally supplied energy into motion tailored to a specific purpose. Furthermore, when combined with sensors and control devices, it allows for precise control over the timing and position of operations.<\/p>\n

Here, we explain how actuators convert energy into motion and how they interact with control systems.<\/p>\n

 <\/p>\n

How Energy Is Converted into Motion<\/strong><\/h3>\n

Actuators are designed to convert energy\u2014such as electricity, pneumatic pressure, or hydraulic pressure\u2014into rotational or linear motion. The basic principle involves transmitting energy to a power source and adjusting the direction and magnitude of the motion according to the application.<\/p>\n

In electric actuators, a motor converts electrical energy into rotational motion, which is then converted into linear motion or angular movement via gears or screws. Pneumatic and hydraulic actuators generate force by applying pressure to air or hydraulic fluid inside a cylinder to move a piston.<\/p>\n

Although the energy sources and structures differ, they share the common goal of producing motion suited to the intended purpose.<\/p>\n

 <\/p>\n

Integration with Control Systems<\/strong><\/h3>\n

By working in conjunction with sensors and control devices, actuators can finely adjust the timing, speed, and position of their operations. To operate machinery and equipment as intended, it is important not only to drive them but also to control them precisely at the necessary moments.<\/p>\n

In security doors, the actuator operates in response to signals from an access control system, locking or unlocking the door based on the authentication result. Depending on the system configuration, it is also possible to check the door\u2019s status and manage opening\/closing history via a network.<\/p>\n

The integration of actuators and control systems allows for a balance between convenience and security.<\/p>\n

 <\/p>\n

Main Types of Actuators<\/strong><\/h2>\n

\"HOW<\/p>\n

Actuators are classified by their power source into electric, pneumatic, hydraulic, and other types. Since ease of control, available force, and required equipment vary by type, it is important to select the appropriate actuator based on the application and installation environment.<\/p>\n

The table below summarizes the characteristics of the three main types.<\/p>\n\n\n\n\n\n\n
\u00a0Type<\/strong><\/td>\n\u00a0Power Source<\/strong><\/td>\nMain Features<\/strong><\/td>\nSuitable Applications<\/strong><\/td>\n<\/tr>\n
Electric Actuator<\/strong><\/td>\nElectricity (Power)<\/td>\nEasy to control; position and speed are easy to adjust<\/td>\nSecurity doors, automated equipment, precision instruments<\/td>\n<\/tr>\n
Pneumatic Actuators<\/strong><\/td>\n\u00a0Compressed air<\/td>\nFast operation and relatively simple structure<\/td>\nProduction lines, conveyors, repetitive motions<\/td>\n<\/tr>\n
\u00a0Hydraulic actuators<\/strong><\/td>\nHydraulic fluid<\/td>\nCapable of generating high forces<\/td>\nLarge safety doors, vehicle gates<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Electric actuators are suitable for precise control, pneumatic actuators for rapid operation, and hydraulic actuators for applications requiring high force. Below, we explain the mechanisms and features of each in detail.<\/p>\n

<\/h3>\n

Electric Actuators<\/strong><\/h3>\n

Electric actuators are devices that use a motor as their power source to drive machinery and equipment. They transmit the motor\u2019s rotation to gears<\/a>, screws, or other components, enabling not only rotational motion but also linear motion and angular movement.<\/p>\n

They allow for fine adjustments to position and speed, making them suitable for applications requiring high levels of control. Another key feature is that they are relatively easy to implement, as they do not require equipment to supply pressure, unlike pneumatic or hydraulic systems.<\/p>\n

They are used in a wide range of applications, including industrial robots and automation equipment, as well as locking and unlocking mechanisms for security doors.<\/p>\n

 <\/p>\n

Pneumatic Actuators<\/strong><\/h3>\n

Pneumatic actuators are devices that use the force of compressed air to move machinery and equipment. They generate linear motion by feeding compressed air into a cylinder to move a piston.<\/p>\n

Because they operate quickly and have a relatively simple structure, they are well-suited for applications requiring repetitive motion, such as material handling on production lines and the ejection of parts. However, their use requires compressed air supply equipment, including a compressor.<\/p>\n

They are widely used in food processing plants, manufacturing facilities, and other settings where speed and ease of maintenance due to their simple design are prioritized.<\/p>\n

 <\/p>\n

Hydraulic Actuators<\/strong><\/h3>\n

Hydraulic actuators are devices that move machinery and equipment using the force of hydraulic fluid under high pressure. Hydraulic fluid is pumped from a hydraulic pump into a cylinder, where it pushes a piston to generate significant force.<\/p>\n

Because they can exert significant force even with a compact mechanism, they are well-suited for applications involving the movement of heavy objects. Typical examples include construction machinery such as excavators and cranes, as well as industrial presses.<\/p>\n

While they are not commonly used in standard security doors, they are a viable option for facilities requiring significant force, such as large gates.<\/p>\n

 <\/p>\n

Main Applications of Actuators<\/strong><\/h2>\n

\"HOW<\/p>\n

Actuators are used in a wide range of fields as components that generate the necessary motion for machinery and equipment. Since the required output, precision, and operating speed vary depending on the application, the appropriate type is selected based on the specific purpose.<\/p>\n

Here, we introduce several representative application fields: industrial equipment and FA equipment, medical equipment and precision instruments, and automatic doors and security doors.<\/p>\n

 <\/p>\n

Industrial equipment and FA Systems<\/strong><\/h3>\n

Actuators are widely used in factory production lines and FA equipment. FA stands for \u201cFactory Automation,\u201d which refers to systems that automate factory production processes.<\/p>\n

For example, they are used in conveyors that transport parts, robotic arms, and positioning devices that move products to specified locations. Electric actuators are used for fine position adjustments, while pneumatic actuators are used for rapid, repetitive motions; each type is selected based on its specific characteristics.<\/p>\n

Actuators are critical components that support the automation of production processes and improve operational efficiency.<\/p>\n

 <\/p>\n

Medical Equipment and Precision Instruments<\/strong><\/h3>\n

Actuators are also used in medical equipment and precision instruments that require precise and subtle movements. Since even the slightest positional deviation can affect the performance of the equipment, a high degree of control is essential.<\/p>\n

For example, they are used for the joint movements of surgical assistance robots, the operation of medical pumps, and the positioning of samples in diagnostic equipment. The use of compact actuators makes it easier to integrate them into limited spaces.<\/p>\n

The ability to combine high-precision operation with compact size is why they are utilized in medical equipment and precision equipment.<\/p>\n

 <\/p>\n

Automatic Doors and Security Doors<\/strong><\/h3>\n

Actuators are also used to open and close automatic doors and to lock and unlock security doors. They are devices that move doors or locking mechanisms in response to signals received from sensors or authentication devices.<\/p>\n

In automatic doors, they work in conjunction with motion sensors and other devices to detect approaching people and control the opening and closing of the door. In the case of security doors, they are combined with access control systems\u2014such as those using IC cards or biometric authentication\u2014to lock or unlock the door based on the authentication results.<\/p>\n

It can be said that a key role of actuators is to support secure access control while enhancing the convenience of doors.<\/p>\n

 <\/p>\n

\u00a0Reasons for Using Actuators in Security Doors<\/strong><\/h2>\n

\"HOW<\/p>\n

Security doors require the ability to lock and unlock reliably and at the appropriate times to prevent unauthorized entry and exit. By utilizing actuators, the locking mechanism can be operated in response to signals from authentication devices or access control systems, thereby automating the locking and unlocking process.<\/p>\n

Here, we explain the main benefits of installing actuators in security doors.<\/p>\n

 <\/p>\n

Automation of Locking and Unlocking<\/strong><\/h3>\n

Using actuators allows you to automate the locking and unlocking of security doors. This mechanism works by transmitting the force generated by a motor to gears or screws to operate the locking mechanism.<\/p>\n

Unlike manual keys, the door locks and unlocks in response to signals from authentication devices, helping to prevent forgotten locks. Another benefit is that the locking mechanism can be operated under predetermined conditions without relying on human intervention.<\/p>\n

If the system needs to function during power outages or emergencies, it is important to include a backup power source and a mechanism that allows for manual unlocking in the design.<\/p>\n

 <\/p>\n

Integration with Access Control Systems<\/strong><\/h3>\n

By integrating with an access control system, actuators can enhance the security of security doors. This system verifies users via IC cards, PIN codes, or biometric authentication, and activates the locking mechanism only upon successful authentication.<\/p>\n

Since only authorized users can enter, this makes it easier to mitigate the risks associated with handing over or duplicating physical keys. Depending on the system, records such as user information and the time of entry can also be stored.<\/p>\n

Combining access restrictions with logging capabilities strengthens a facility\u2019s security management.<\/p>\n

 <\/p>\n

Supports remote operation and centralized management<\/strong><\/h3>\n

By implementing a network-connected system, multiple security doors can be managed collectively. A key benefit is that administrators can lock, unlock, and check door statuses from a single location.<\/p>\n

For example, in facilities with many doors to manage\u2014such as office buildings or factories\u2014this reduces the effort required to check each door individually on-site. Depending on the system, it may also support notifications of anomalies and the review of opening\/closing logs.<\/p>\n

Remote operation and centralized management help streamline administrative tasks while maintaining security throughout the entire facility.<\/p>\n

 <\/p>\n

\u00a0Key Considerations When Selecting Actuators for Security Applications<\/strong><\/h2>\n

\"HOW<\/p>\n

When selecting actuators for security doors, it is not enough for them to simply provide the required force. To ensure stable operation over the long term, selection must take into account the door\u2019s structure, frequency of use, and installation environment.<\/p>\n

Here, we explain four key points to consider during selection: torque, durability, quiet operation, and power consumption.<\/p>\n

 <\/p>\n

Determining the Required Torque<\/strong><\/h3>\n

When selecting an actuator for a security door, it is important to verify the torque<\/a> required for locking and unlocking. Torque is the force that rotates an object, and the required amount varies depending on the structure of the door and the locking mechanism.<\/p>\n

If the torque is insufficient, the lock mechanism may not move properly, potentially resulting in incomplete locking or unstable operation. When selecting an actuator, it is necessary to compare the actuator\u2019s output with the actual load conditions.<\/p>\n

For equipment requiring significant force, such as large gates, pneumatic or hydraulic systems may also be viable options depending on the application.<\/p>\n

 <\/p>\n

Verify Durability and Reliability<\/strong><\/h3>\n

Since security doors are used repeatedly, actuators must possess the durability and reliability to withstand long-term operation. The more frequently a facility is used, the more important it is to select an actuator that accounts for the impact of component wear and failure.<\/p>\n

When comparing products, be sure to check the operational lifespan, endurance (number of cycles), operating temperature range, and dust- and water-resistant performance. In outdoor or industrial settings, it is also necessary to consider the installation environment, such as temperature fluctuations, dust, and moisture.<\/p>\n

Selecting a product suited to the intended application and environment leads to stable security operations and reduced maintenance burdens.<\/p>\n

 <\/p>\n

Check for Quiet Operation<\/strong><\/h3>\n

In offices, medical facilities, hotels, and similar settings, the quiet operation of actuators is a key selection criterion. Loud motor or gear noise every time a door is locked or unlocked can compromise user comfort.<\/p>\n

Electric actuators equipped with low-noise motors and high-precision gears are effective for minimizing operational noise. In particular, even slight operational noise can be a concern near patient wards or conference rooms, as well as in facilities that remain open at night.<\/p>\n

It is important to select a product with the necessary quiet operation performance, taking into account the usage environment of the installation site.<\/p>\n

 <\/p>\n

Check Power Consumption<\/strong><\/h3>\n

When selecting actuators for security doors, it is also important to check their power consumption. This is because, in facilities that operate a large number of doors, even if the power consumption per unit is low, it can still impact overall electricity costs for the facility.<\/p>\n

Selecting motors or products with high efficiency or low standby power consumption can help reduce overall power consumption. Additionally, when using batteries or a UPS (uninterruptible power supply) during a power outage, power consumption is one of the factors that determines the required backup capacity.<\/p>\n

Be sure to check the rated voltage and electric current values as well, and select a product that meets your operational requirements.<\/p>\n

 <\/p>\n

Summary<\/strong><\/h2>\n

\"HOW<\/p>\n

An actuator is a drive device that converts energy\u2014such as electrical or pneumatic power\u2014into mechanical motion to support the opening, closing, and positioning of equipment. In security doors, actuators contribute to improved safety and management efficiency by automating locking and unlocking and integrating with access control systems.<\/p>\n

However, the required performance varies depending on the door\u2019s weight, frequency of use, and installation environment. To ensure stable operation, it is important to verify factors such as torque, durability, quiet operation, and power consumption, and select an actuator suited to the application.<\/p>\n

In the case of electric actuators in particular, the performance of the internal motor is also a key factor that influences operational stability and durability. Be sure to perform appropriate motor selection based on the actuator\u2019s intended use and the required performance.<\/p>\n
