Selecting the Right Linear Actutator for Your Application
There are four general types of linear actuators:
Non-Captive
External Linear
Captive (Electric Cylinder)
Kaptive
Why Choose One Linear Actuator Form Factor Over Another?
We recommend asking the following questions to assess your linear actuator needs for a specific application.
What is the best mechanical fit for your application?
How do you plan to attach the end of the screw?
Is it necessary that the screw be secured from rotation?
Does the application require an encoder?
What is the stroke of the application?
Environmental Considerations
Linear actuators are typically designed to operate in dry and non-corrosive environments, unless an ‘IP rated’ product is specifically requested. Operating non-IP rated linear systems in dirty or corrosive environments significantly reduces product life.
Temperature
Very high or low temperatures may cause significant changes in nut fit or drag torque.
Maximum Dynamic Load
Each Nema frame size motor has a mechanical load maximum that should not be exceeded, based on speed / torque curves for each frame size.
Motor and Drive Selection
In order to select the right motor / lead screw combination, several factors should be considered:
How much torque is required?
What is the desired step angle? (1.8 or 0.9 degree)
What are detent or holding torque requirements?
Physical size restrictions?
What type of driver (amplifier) does the application require?
Clearly, there are a number of variables that go into choosing the right linear actuator solution for your specific application.
