What Are Electromechanical Linear Actuators and Their Types?
Across the technology that we rely on every day for various activities, there are many smaller internal components that provide critical functionality for those systems. An electromechanical linear actuator is a component that belongs to the Federal Supply Class 1680 Miscellaneous Aircraft Accessories and Components. Electromechanical linear actuators are a specialized type of actuator that transforms rotational motion into linear motion, typically in the form of a push or pull movement. These components may be used for a variety of applications, including furniture, medical systems, and industrial processes. In this blog, we will discuss what electromechanical linear actuators are, a few common types, and how they benefit the systems they are featured in.
As compared to other types of linear actuators, the electromechanical linear actuator utilizes an electric motor to harness rotational motion to produce linear displacement. While there are multiple designs and types, most electromechanical linear actuators function with similar principles and hardware. In general, the actuator will have an electric motor that rotates a lead screw. This screw is externally threaded across the shaft, and a mating nut is installed within the assembly which remains static during rotation. With this permanent placement, the nut remains still as the screw is rotated, causing it to travel along the shaft on the threading. As the nut travels along the rotating screw, the screw is forced upwards or downwards depending on rotation direction, thus creating linear displacement. Across designs, a balance is struck between high speed and force and properties may be favoured depending on the intended use and application.
The inline actuator is a type of electric actuator that is engineered to cater towards small and compact areas of an assembly, featuring a longer retracted length. The typical components that comprise the inline actuator type include a motor, planetary gear assembly, and drive spindle. Inline actuators may be used for a variety of functions, including those such as opening doors, hatches, windows, and more for systems belonging marine, aviation, and other industries.
The gear motor electromechanical linear actuator is a type that highly benefits mechanical synchronization. With a gear motor, more flexible and economical designs may be made. The gear motor actuator type may also be worm gear driven, as well as more compact as compared to other types.
Unlike some of the other electromechanical linear actuators, the dual motor actuator type may provide motion in two directions that can either be conducted independently from one another, or simultaneously. With a dual motor type, a system may be able to perform critical operations with less linear actuators. As dual motor actuators are often driven by worm gear motors, they tend to perform with a lower noise level.
Electromechanical linear actuators, while simplistic by themselves, may provide a variety of benefits for various applications. They are also manufactured from a number of manufacturers including AlliedSignal Inc., Automatic Switch Company, GE Aviation Systems LLC, Honeywell Aerospace, and many more.
