Electronic actuators are devices that convert electrical energy into physical motion. They play a key role in automation, offering precise control over various operations. These actuators provide superior accuracy, efficiency, and reliability compared to traditional mechanical systems. As a result, their demand has notably increased across diverse industries.
These industries use the following types of actuators:
Linear Actuators
Linear actuators generate straight-line motion from an electrical input. Accordingly, people get this motion using two main methods: the electromagnetic method, where they get the electric current through magnetic field interaction, and the piezoelectric method, where they get the motion from the piezoelectric effect. Businesses mainly use these actuators to push, pull, lift, lower, tilt, and move objects in systems. Common applications involve processes such as precise control of valves, pumps, and other mechanical systems.
Rotary Actuators
Rotary actuators produce rotational movement. They mainly achieve this by converting different types of energy, whether from air pressure, electromagnetic fields, or hydraulic systems. Also, they are essential components for any automation system that requires mechanical movement. Mainly, people use them in robotic arms for rotating joints, gears, and pulleys driving systems, heavy machinery mechanics, and automated valves.
Hybrid Actuators
Hybrid actuators combine two electric motor-driven actuators into one. That means people can frequently find hybrid actuators in high-precision applications such as aerospace and defense. More importantly, hybrid actuators enhance performance by providing the benefits of both linear and rotary motion. That means they will be a good fit for systems requiring complex movements. Moreover, these multi-functionality capabilities help reduce the space and cost of extra equipment.
Automotive Industry
The automotive industry continues to integrate modern controls into its operations to increase efficiency. Thus, it is no surprise that automobile dealers widely use electronic actuators. They use these actuators for various applications, including engine control, where precise air-fuel mixture adjustments are vital.
Electronic actuators play a central role in vehicle safety and comfort features, too. For example, Electronic Stability Control (ESC) systems use vehicle sensors to automatically adjust individual wheel brake actuators. This helps develop a stabilizing effect.
To achieve all these, there must be an effective actuator controller. This helps produce the required movement. Therefore, while placing orders, buyers should consider the variety of actuators and their corresponding applications in the client's industry to make an informed choice.
Aerospace
In the aerospace sector, precision and reliability are the main requirements for control actuators. Dealers will find that Hybrid actuators are among the most preferred types in this space, particularly in flight control systems, where small adjustments can affect the flight path. Aerospace companies prefer hybrid actuators because of their superior performance, which helps drive demand for electronic controls in this industry.
Healthcare and Medical Devices
People use electronic actuators a lot in the healthcare sector, especially in medical equipment. Because these are critical life applications, the industry has to use actuators with high precision, reliability, and efficiency. The medical devices that use electronic actuators include infusion pumps that precisely control medication flow, robotic surgical systems that enhance the surgeon's ability to perform minimally invasive procedures, and prosthetics.
These depend on actuators for movement and functionality. Additionally, electronic actuators help ventilators, which control the breath of the patients. Overall, medical devices of all kinds use electrical actuators to improve patient outcomes.
Industrial Automation
Electronic actuators are some of the most commonly used components in industrial automation. Dealers use them to drive robotic systems in manufacturing processes. These actuators apply control over robotic arms performing assembly, welding, and painting operations with high precision.
Moreover, electronic actuators help control valves and other equipment in industrial processes. Basically, their automation integration improves efficiency and reduces production time while increasing product quality. So, it will be worth ensuring that there are industrially applicable electronic actuators when placing orders for clients working in the Automation industry.
Electric actuators
As mentioned earlier, electric actuators convert electrical energy into motion. They do this using electric motors. Of the three electric actuator types, the linear electric actuators are the simplest. As explained above, they produce linear motion. Generally, electric actuators are very accurate, require little maintenance, and are easy to control electronically to provide precise movements.
Hydraulic actuators
Hydraulic actuators use fluid pressure to create motion. They are powerful, can handleheavy loads, and withstand harsh environments. However, they do not come without their own set of drawbacks, too. For instance, they require more maintenance than electric actuators and need a hydraulic fluid system installation.
Pneumatic actuators
Pneumatic actuators, just like hydraulic actuators, are powerful. They use compressed air to create a motion. Compressed air provides a fast operation, making them an ideal option for processes requiring quick movements. That said, the main challenge with pneumatic actuators is that they are less efficient and may require additional equipment for air compression.
Proper installation of an Electronic Actuator Controller ensures the system run smoothly. The first step is securing a mount for the actuator. Then, after mounting it out, the next step is to connect the power supply. Next, to provide the control signal, one has to wire the controller to the corresponding signal output device. After this, one then connects the feedback devices to the controller.
Then, to establish communication, one has to set up the controller, then check the parameters to verify the correct configuration. Finally, one has to conduct a system test to ensure it works properly.
One of the most effective ways of increasing the durability of electrical actuators is by routinely inspecting them. Additionally, cleaning them helps reduce wear and tear, as well as ensuring its performance. Other key maintenance practices include routine checks for wear on components and conducting timely repairs, as well as monitoring systems and keeping an eye on operating conditions to catch issues early on.
Accessories
These components are crucial since they help improve the functionality and performance of an electric actuator. For instance, mounting brackets help with the installation of an actuator, hence preventing misalignment. Moreover, they add more stability.
Additionally, sensors such as position sensors provide feedback, enabling more precise control of the actuator. Moreover, users can add customized end fittings that will allow them to connect the actuator to the specific components they will be moving.
Moreover, power supplies ensure a consistent and reliable energy source for the actuator systems. Further, users can also add limit switches to prevent over-traveling by automatically stopping the actuator when it reaches its endpoints.
Customization Options
Many manufacturers offer customization options for their electronic actuators to meet the specific needs of their customers. For instance, they allow customers to specify actuator size and the load it can handle to suit their spaces and achieve their required objectives.
Customers can also use different materials to coat the actuators to prevent them from harsh chemicals or extreme temperatures. Also, there is software customization for electronic actuators, which is a big plus. Manufacturers will now allow customers to adjust control parameters, which will enable them to use the actuator in different applications.
Lastly, clients can also ask for custom feedback mechanisms to offer the kind of performance feedback that will best suit them.
Electronic actuators and controllers can malfunction due to a number of reasons. Sometimes, the hardware itself is faulty, while other times, the failure could be due to either software issues or user error. This, therefore, means that there are various preventative measures users can take to improve the reliability of their electronic actuators.
Quality Components
Using quality parts ensures reliability and long-term durability. This means users should only get these electronic components from suppliers known to stock them. Fortunately, there are tons of customer-reviewed suppliers on Alibaba.com. Everyone considers these electronic components in their production. So, by using electronic actuators built with quality materials, customers will minimize the probability of damage occurring. There are several types of controlling electronics actuator controls in this section. So, buyers can curate their orders based on their customers' preferences.
Proper Installation
As discussed earlier, customers should ensure the controller and actuator are properly installed together for the device to operate properly and ensure safety. They should also ensure that the components are properly connected and there is no chance of anything disrupting the connection.
Additionally, they should educate their staff on safe working practices to avoid them putting themselves in hazardous situations. Also, they should encourage them to avoid touching the components with bare hands, as there is the possibility of transferring oils and dirt that can cause damage.
Routine Monitoring
Additionally, users should set up a routine monitoring system to enable them to know the components' exact state as they operate. A monitoring system will also help ensure all the feedback mechanisms are working to detect any irregularities early on before they turn into disasters.
One more thing, even with the most precise monitoring, a time-worn electronic actuator will eventually become one. So, clients should ensure they replace old actuators to avoid more breakdowns and reduced efficiency. When searching for old and new model electronic actuators, buyers can check out the new arrivals section on Alibaba.com.
Protect Against Overload
Using electronic actuators beyond their load capacity is one of the most harmful things users can put them through. Therefore, they should invest in load cells to measure the load and ensure the actuators operate within safe limits. Contraints, overloads can result in overheating, mechanical failure, and even damage to the controller.
Besides, users should also educate their staff on recognizing the various symptoms of actuators under stress. Normally, these symptoms will be accompanied by slower operating speeds, strange noises, or even an unexpected shutoff. When users notice any of these signs, they should stop the operations immediately and start troubleshooting the issue. They should also avoid temporarily patching the problem and forcing the actuator to continue working.
A1. There are a number of problems electronic actuators can face. However, some are more common than others. For instance, one of the most common issues is the loss or decline in accuracy. An inaccurate actuator affects system performance. In worse cases, internal component wear, thermal expansion, and electrical noise propagation will cause this decline.
Another common problem is electrical noise. Noise can disrupt an electronic actuator's control signal, causing erratic movement. Difficult operational environments with extreme temperatures, dust, or moisture can also cause electrical noise.
A2. Yes, there are weatherproof actuators that can withstand extreme temperatures. However, it is important to ensure that the electronic components manufacturers have rated them for such environments. In extreme heat or cold, electronic actuators can degrade. This is the reason there are outdoor electrical devices. Note that thermal expansion and contraction can cause mechanical stress. Therefore, there has to be a way to manage heat effectively.
A3. People use electric actuators across different industries. These industries include the automotive industry, aerospace, robotics, manufacturing, and medical devices, just to mention a few. In these industries, electric actuators are used in equipment, such as CNC machines, robotic arms, assembly lines, and valves. They are ideal for these applications because of their precision and reliability.
A4. Simply put, the answer is yes. The more the electric actuators, the better. Each actuator should have a separate controller for more electrical actuators and a bus system to interconnect them all for efficient management. More electric actuators mean more operational efficiency. The controllers improve movements and provide more energy for enhanced accuracy. Therefore, operationally, buyers should try to get as many electric controllers as possible.
