Linear Actuators: Types and Characteristics
A Linear Actuator is totally different from electric motor because it applies power in a linear way instead of rotationally. The linear motion could be achieved in numerous ways and a linear actuator is among the devices that may covert rotational motion to linear motion.
Mechanical type
A mechanical actuator converts the rotary motion to linear displacement by means of screws/gears to which a knob is attached. One of the renowned examples of mechanical actuator is a jackscrew or car jack. Mechanical actuator is used in lasers and optics for manipulating the position of mirror mounts, linear stages and many more positioning instruments.
Hydraulic type
A hydraulic actuator or cylinder has a hollow cylinder with a piston inside it. Controlled linear displacement of the piston is achieved by pressurizing/de-pressurizing sides of the piston. Hydraulic automotive jack is the most typical instance of a manually operated hydraulic actuator.
Electro-mechanical type
A linear electromechanical actuator is a in which a nut is the primary part of the motor. The lead screw of the actuator doesn't rotate and the lead nut is rotated by the motor. It is much like mechanical actuator but an electric motor is used instead of a control knob or handle.
The trendy linear actuators come in several designs and every manufacture has their own proprietary strategies of making actuators.
Rules of Linear Motion Actuators
The essential operation principle of linear motion actuators is an inclined plane. The lead screw has threads, which act as ramp and allow small rotational drive that can be utilized over long distance for achieving the movement of huge load within a shorter distance.
Variations in Linear Motion Actuators
There are different variations in the basic design of linear actuators. Many of the devices have general improvements like higher speed, effectivity or load capacity. Nowadays, producers are also focusing more on reducing the size of these actuators. There's variety of actuators available in market, which fits specific industrial wants of buyers.
What make linear motion actuators higher in comparison to other motors are their faster velocity, higher accuracy and better acceleration. These are used for gantry axes, general function position, gantry axes and assembly machines. Linear actuators are specifically meant for use in adverse conditions and act as replacement against different hazardous actuators for performing the job.
Apart from linear actuators, DC actuators are also used for performing similar applications. These run smoothly and don't produce much noise. Many DC actuators available within the market are water proof. Buyers can opt for commonplace as well as customized range of actuators relying on their need and budget.
