A Linear Actuator is totally different from electric motor because it applies pressure in a linear way instead of rotationally. The linear motion could be achieved in numerous ways and a linear actuator is one of the units that can covert rotational motion to linear motion.

Mechanical type

A mechanical actuator converts the rotary motion to linear displacement by screws/gears to which a knob is attached. One of many renowned examples of mechanical actuator is a jackscrew or automotive jack. Mechanical actuator is used in lasers and optics for manipulating the position of mirror mounts, linear phases 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 automobile 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's much like mechanical actuator but an electric motor is used instead of a control knob or handle.

The modern linear actuators come in numerous designs and each manufacture has their own proprietary methods of making actuators.

Ideas of Linear Motion Actuators

The basic operation principle of linear motion actuators is an inclined plane. The lead screw has threads, which act as ramp and permit small rotational drive that can be utilized over long distance for achieving the movement of enormous load within a shorter distance.

Variations in Linear Motion Actuators

There are totally different variations in the fundamental design of linear actuators. Most of the units have general improvements like higher velocity, efficiency or load capacity. Nowadays, manufacturers are additionally focusing more on reducing the dimensions of these actuators. There is variety of actuators available in market, which fits specific industrial wants of buyers.

What make linear motion actuators better in comparison to other motors are their quicker pace, 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 in opposition to different hazardous actuators for performing the job.

Apart from linear actuators, DC actuators are additionally used for performing similar applications. These run smoothly and don't produce a lot noise. Many DC actuators available within the market are water proof. Buyers can go for customary as well as customized range of actuators relying on their need and budget.
