An electric actuator is a device that can bring about the movement of a load or a resultant action requiring force with the use of an electric motor. It is a mechanical device that is used to change a supply of electrical energy into kinetic energy that can be harnessed and used in various applications. Read More…

How Electric Actuators Work
An electric motor can generate a rotary motion when its spindle or rotor rotates in a circular motion. The rotor is directly connected to the helical screw through a drive shaft, which provides a rotating force to the ball screw nut. The ball screw is moved either backward or forwards along the helical screw. Another hollow piston rod thereby creates linear motion. The rotation speed is varied by controlling the electric drive.
The power of the motor determines the overall torque. A communicating mechanism will provide the position information of the shaft and determine whether a stop or a change in direction is required. The linear electric actuator can be programmed and set to move in a specific direction until it reaches a certain position and then either stop or move on or maybe return to the rest position.
Considerations When Choosing an Electric Actuator
When deciding on whether to adopt the usage of an actuator, one needs to consider the type of force they require. For example, there are pneumatic linear actuators where the force is created by a pressure exerted on the surface area of the piston.
Electric actuators are an alternative when there is no supply of compressed air. When using electric actuators, the force is generated by the torque capability. A linear electric actuator is required when the system has multiple positions where a change in direction or force is required.
Types of Electric Actuators
Electric actuators can be divided into two main subcategories: rotary and linear.
Rotary Electric Actuators
Rotary actuators rotate from closed to open through the use of butterfly valves, plug valves, and a ball. The electromagnetic power from the electric motor makes the components rotate, allowing halts during each stroke. The rotary electric motors also provide an incremental rotating movement in the output shaft.
Its most basic form consists of a motor coupled with a speed reducer. They incorporate a wide range of additional components such as clutches, brakes, rotating gears, and seals.
Linear Electric Actuators
Linear electric actuators use an acme screw setup or sometimes a motor-driven ball to provide linear motion. The load is usually connected to the screw end, which is belt or gear-driven. The acme screws will hold loads without power and are less efficient when compared to the ball screws.
Their robust nature to shock loads affects the actuator's general lifespan, unlike ball screws which run smoothly without any friction and, therefore, have greater efficiency.
Applications and Benefits of Electric Actuators
The applications and benefits of electric actuators include:
Applications of Electric Actuators
Electrical actuators are made use of in a wide variety of industrial applications. For example, they are used in the food and beverages industry to manufacture PET bottles, labeling systems, filling components, and robotic milking machines. In addition, the automotive industry uses actuators in driverless motor vehicles.
Other applications are in dispensing and selecting jointing methods like welding and reverting. They are also used in agricultural equipment where they are fitted to powered hydraulics for more finessed movements. Cutting equipment also makes use of actuators in the lowering or precise movement of the cutting blades.
Advantages of Electric Actuators
Electric actuators are very accurate at controlling movement or the equipment's general position. They also do not require extensive maintenance as their setup is not complex.
Electric actuators also have dependable efficiency when used at very high speeds. Finally, the actuators come with very little operating cost since they use electrical energy and do not require numerous additives to function.
Choosing the Proper Electric Actuator Supplier
To ensure the most constructive outcome when purchasing electric actuators from an electric actuator supplier, it is important to compare several companies using our directory of electric actuator suppliers. Each electric actuator supplier has a business profile page highlighting their areas of experience and capabilities, along with a contact form to directly communicate with the supplier for more information or request a quote.
