The electric linear actuator is a reciprocating actuator driven by a motor. It is suitable for all linear motion which needs reciprocating and pushing. It can swing and rotate by means of other connecting rods.The electric linear actuators are suitable for low to high duty applications in most industry sectors and offer a better solution than hydraulic and pneumatic actuators in most cases.

What is the Working Principle of Electric Linear Actuators?

The basic working principle of electric linear actuator is to convert the rotary motion into a linear motion. This conversion of motion is done with the help of a gearbox and a lead screw. These are the two most important electric linear actuator parts. Expect gearbox and lead screw , there’re six spare parts including motor,limit switch , DC brushes, gears,cylinder .As compared to the others, these actuators consist of fewer working parts. Thus, very little maintenance is required. Also, it makes the devices easy to operate.

How Do the Electric Linear Actuators Work?

· The working of the actuator starts with the rotor and the stator assemblies. These assemblies facilitate the primary and secondary workings of the motor.

· Voltage is applied to the stator assembly, which acts as the primary workings. This voltage is then converted into a current. This current is shunted into the rotor assembly, which acts as the secondary workings.

· The working of the rotor and stator assemblies, helps create a field, which facilitates motion.

· The motion created by the motor is then passed to the cylinder. Here, cylinder interacts with the limit switch to convert this motion into a linear one.

· The cylinder is turned by the gears, which helps promote the linear motion.
