Selecting the Right Linear Actuator Motor

      Selecting the Right Linear Actuator Motor 沒有評論

Linear actuators are utilized inside a number of applications like healthcare gear, test instruments, factory processes and assembly machinery. Because every application may have its personal overall performance and security specifications, actuator choice may be difficult. Improper choice nearly usually outcomes in premature failure and costly upkeep price when undersized, or higher initial price if oversized.

Our Types of 12V Linear Actuators Recommedation

As a leader in linear automation technology we aim to have to many different types of 12V linear actuator motor so our customers will have a variety of different options available. Whether it be high speed, heavy duty, miniature or track actuator models, we have them all. In this post we’ll go over our different types of electric linear actuator models and the advantages of each one.

Heavy Duty

On the other side of the spectrum is our largest actuator model which also products the largest amount of force. The heavy duty 12V actuator is capable of producing a whopping 2,000 lbs of force, making it the perfect choice for applications that require massive amounts of lifting such as construction equipment and heavy machinery.

Actuator Orientation

The actuator orientation will dictate the size and kind of motor required to drive the actuator also because the load ratings for the actuator motor mixture. An actuator inside a vertical orientation may have a reduce load capability and also the use of an electromagnetic brake motor is extremely suggested to stop the load from falling throughout a energy failure occasion. Inside a horizontal orientation, the highest load capacity may be accomplished along with a brake won’t be needed. When comparing the two orientations utilizing exactly the same load, a vertical actuator will need a bigger much more potent motor in comparison to exactly the same actuator mounted horizontally.

Stroke length

When determining your application requirements to select your linear actuator, careful consideration needs to be taken to make your selection based on metric units. Choosing the correct actuator length will depend on whether one or two blocks are used, where an actuator with two blocks will have a longer overall length for the same stroke. Keep in mind the overall length of an actuator is going to be the working distance of travel plus the “dead length” at either end of the actuator typically consisting of the motor, coupler and mounting bracket.

Force & Velocity

In case your application entails influence or an abrupt quit, you might have to think about the influence force to appropriately mount and insulate your method. Understanding the force and velocity of one’s application is crucial since it can impact choice of other components of one’s linear actuator like the ball screws, nuts and also the motors. The influence force (that is usually twice as a lot because the typical force) can help you figure out the inertial forces for cushioning. Whilst the total force (the sum of acceleration force, frictional force and breakaway force) can help you comprehend the preferred motion you are attempting to produce and assist choose the proper size actuator and motor.

Loads & Moments

The position of the load plays an important factor in choosing the correct actuator. Overhanging or cantilevered loads can create moments or twisting forces on the carriage of the actuator calculated by multiplying the force by the distance offset from the actuator axis. If the allowable moment is exceeded, the linear actuator could suffer damage. Based on the combination of the actuator orientation and the load position, there may be moment loads in as many as three directions. Each direction needs to be evaluated and verified against the allowable moment load of the actuator. The further the load is from the center axis, the larger the resultant moment.


Even if you take the time to determine all the above factors, if you fail to consider the part that your environment will play in the performance of your actuator you could be setting yourself up for disastrous results. Before you select your linear actuator, you also need to know if it will be used in extreme heat or cold temperatures, if it will be subject to dirty or wet conditions and if it will be in contact with any corrosive chemicals. These conditions can often times call for the use of cleanroom-rated actuators.
