subject: Linear Actuators Provide Proficient Automation Solutions [print this page] When it comes to automation and handling, the job of a liner actuator can never be underestimated. As opposed to a regular electric motor, this type of an actuator functions on a push and pull mechanism. This push-pull happens in a straight line (which explains the use of the term linear). For instance, when you give a print command, the printed paper is ejected using the aforementioned mechanism. This mechanism is used in varied applications ranging from metrology to microbiology to handling to guided micro-positioning. A regular electric motor usually works in a rotational or rotary manner. But this type of an actuator usually provides motion in a straight line and sometimes operates on hydraulic or mechanical actuation techniques. Hence it is also known as a linear motor.
Now lets take a look at how to choose the right linear actuator:
* Decide on the amount of force required: Do you need a lot of friction or force to be applied? This will determine what type of an actuator you should be choosing. If you need a lot of force, you will have to opt for an advanced version of an actuator. Otherwise, if you do not need much force or friction, a basic model will suffice.
* Decide on the speed required for the task: Sometimes, you might need very rapid motion. At other times, you might need motion with a gap. Since both these are varied requirements you will have to choose different kinds of actuator for each task. Talk to your supplier if you need slow motion but great force and vice versathis is what will determine the force needed.
* Decide the length of the strokes: Some tasks require your actuator to have long strokes, whereas some require shallow strokes. This will also determine if you want to customize your linear actuator or go with the standard available machine.
* Check the duty cycle rating: Some actuators tend to overheat if they are operated continuously. This will be an important factor in the type of task you are performing. If you need continuous functioning, you might want to check out the high end servo units.
* Check your power supply: You need to decide whether you are going to opt for a battery operated actuator or an electrically powered one. A battery operated linear actuator will require a DC motor. But even if you have an AC motor, it can be converted to DC. This will not have much effect on your motion control.
