What is electric linear actuator?
An electric linear actuator is a device that converts an AC or DC electric motor’s rotational motion into linear motion. The linear motion is created by rotating the actuator’s screw via the motor. Electric linear actuators also provide safe and clean movements with accurate motion control and full operator control.
What is an electric actuator used for?
An electric actuator is a mechanical device used to convert electricity into kinetic energy in either a single linear or rotary motion. It automates damper or valve in order to increase process efficiency and complexity.
Where linear actuators are used the most?
A linear actuator is an actuator that creates motion in a straight line, in contrast to the circular motion of a conventional electric motor. Linear actuators are used in machine tools and industrial machinery , in computer peripherals such as disk drives and printers, in valves and dampers , and in many other places where linear motion is required.
What are electric actuators used to accomplish?
Electric actuators that produce quarter turn movements are used in a wide range of industries for precise positioning of rotary valves such as ball valves, plug valves, choke valves, butterfly valves, and dump valves. These actuators can also be used in air/fluid dampening applications.
Are clutches available on the linear actuators?
Clutches/torque limiters are available on most of Power Jacks linear actuators whether as a standard option or a custom design. The EMA-Series linear actuator have a standard friction clutch option. The friction clutch in these actuators is set to slip when the rated load limit of the actuator is exceeded. This is to prevent damage to the actuator due to jamming or over-heating resulting from an excessive load.
What is the stroke of a linear actuator?
Stroke is the distance travelled by an actuator in motion. This is a measurement of the capability of a linear actuator. The stroke will help you determine whether the actuator will work in tandem with your application.
