How do linear actuators work?

A common type of linear actuator is an electric linear actuator. It is made up of three main components: spindle, motor and gears. The motor can be AC or DC depending on the power needs and other influencing factors.

Once a signal is sent by the operator, which can be through a control as simple as a button, the motor converts the electric energy into mechanical energy, rotating the gears connected to the spindle. This rotates the spindle and causes the spindle nut and piston rod to travel outwards or inwards depending on the signal to the actuator.

As a rule of thumb, a high thread count and smaller spindle pitch will cause slow movement but a much higher load capacity. On the other hand, a low thread count, and higher spindle pitch, will favour fast movement of lower loads.

What are the different types of electric linear actuators?

There are many types and sizes of electric linear actuators. From small and compact that fit into tight spaces, such as in wheelchairs, to large and powerful to move heavy items like a wheel loader engine hood. In addition to size and power, there are also many different designs of electric linear actuators.

The original design has a motor housing that is outside of the gear and spindle profile. But when space is limited, an inline actuator is used so that the motor only extends the shape of the profile. For desks and some medical applications, lifting columns are used for an inline motor housing with two and three-stage options.

Since the founder and CEO of LINAK, Bent Jensen, made his first electric linear actuator in 1979, the company has continued to develop new actuators and refine the innovative technology behind them to improve movement solutions for several industries.

LINAK designs and manufactures many types of linear actuators and lifting columns with various speeds, stroke lengths, and capacities. From the compact, inline LA20 to the robust LA36, LINAK actuators are built to fit almost any application.

With an almost endless list of customisation options to help design an actuator specifically to fit unique applications, the range of LINAK actuators is even greater than the vast product range listed.

What is a linear actuator?

A linear actuator is a device or machine that converts rotational motion into linear motion and linear movement (in a straight line). This can be done through electric AC and DC motors, or the movement could be powered by hydraulics and pneumatics.

Electric linear actuators are a preferred option when precise and clean movement is needed. They are used for all types of applications where tilting, lifting, pulling or pushing with force is needed.

What is a linear actuator used for?

Actuators can be found anywhere, in homes, offices, hospitals, factories, farms, and many other places. Our electric actuators bring movement to the office and home with adjustable options for desks, kitchens, beds, and couches. In hospitals and medical centres, you will find actuators adding movement to hospital beds, patient lifts, surgery tables and more.

For industrial and rugged environments, electric linear actuators can replace hydraulic and pneumatic solutions found in agriculture, construction, and in industrial automation equipment.

Why use a linear actuator?

Electric linear actuators increase efficiency and give users precision movement through a variety of control options and accessories. Control options for electric linear actuators include handsets, footswitches, desk controls, computer software, mobile apps and much more.

With no need for hoses, oils, or valves, electric linear actuators require no maintenance and create a safe environment for users. High-quality electric actuators are also put through a variety of tests that push the actuators to extremes. This is done to ensure optimal performance at any given time in any situation. They are also designed, along with their accessories, to be easily mounted and installed in a variety of applications,

making it easy for anyone to add precision movement where they need it. Being electric enables the addition of smart features like CAN bus (LINAK offers CAN SAE J1939 and CANopen for actuator controls). Integrated Controller (IC) solutions can provide various position feedback options, virtual limits, soft start and stop, current limitation, and adjustable speed.

CAN bus - How to see which CAN bus version you are running

At LINAK®, we currently supply actuators with two different CAN bus software versions - v1.x or v3.x.

Determine the actuator version with the LINAK BusLink software
Connect the actuator to the BusLink software to verify the correct software version. When the actuator is connected you can find the ‘Connection Information’ tab. In the example below, the LA36 CAN bus actuator has version 3.0.

For further information, please see the BusLink service interface chapter in the CAN bus user manual.

BusLink version 3.0

What is the difference between version 1.x and version 3.x?
On CAN bus v3.0, we have introduced several new functionalities - such as hardware addressing, dynamic speed adjustment, soft start/stop commands and increased compatibility (125 kbps, 250 kbps, 500 kbps and Autobaud).
Please note that the soft start/stop now needs to be defined in the CAN bus command (in version 3.x). If left at 0, it will result in no ramping. If set to 251 it will use the actuator’s predefined factory settings. Any number in between will set the ramping time.

For further information, please see the Communication chapter in the CAN bus user manual.

IC parallel actuator system - How to add, remove, or replace an actuator

How to add, remove or replace an actuator in your IC™ parallel actuator system.

To add or remove an actuator:

  1. Connect all actuators to BusLink to configure the number of actuators in your parallel system
  2. Before running the system, let the system initialise itself

To replace an actuator:

  1. Power the system off and replace the actuator
  2. Power the system on and the new actuator will automatically catch up to the position of the remaining actuators

For more information about initialising your parallel IC system, please visit How to initialise your IC™ parallel actuator system.

IC parallel actuator system - How to initialise the system

How to initialise your IC™ parallel actuator system.

Initialise the system in two ways:

  1. Let the system initialise itself via Recovery mode, where the actuators automatically run in steps of 2000ms on and off for a full stroke length
  2. Initialise the system manually by using the BusLink software. Only the actuator in ‘position lost’ needs to be initialised by running the actuator to its mechanical endstop in one direction

For information about troubleshooting on your parallel IC system, please visit How to troubleshoot on your IC™ parallel actuator system.

IC parallel actuator system - How to troubleshoot on the system

How to troubleshoot on your IC™ parallel actuator system.

If an actuator has lost its position, the parallel system will enter Recovery mode and initialise itself. If the system is unable to run in recovery mode, please continue this troubleshooting process:

  1. Check cabling, power supply and communication signals between actuators
  2. Connect each actuator to the BusLink software and look at the error codes to identify which actuator has caused the system to stop

If it is an overcurrent error code, restart the system by running it in the opposite direction.

If these error codes are registered, actuator replacement is necessary: H-bridge fault, switch mode power supply fault, or hall sensor failure.

Lifetime prediction

All LINAK® products undergo long-term functional testing and end-of-line tests in order to ensure a high level of quality and lifetime durability. We have taken this one step further. As a result of intensive testing and reliability studies, we offer B10 life on the LA36 actuator to help you predict the actuator lifetime for your applications.

Learn more about B10 life and what it can do for you here.

What is B10 life?
B10 life is the statistically calculated estimate of the number of cycles that 90% of the actuators will meet when used in accordance with product specifications. Meanwhile, 10% might fail. A component can fail before reaching the B10 life; consequently, the B10 life is not a guarantee. The B10 values are defined based on the results of long-time testing of our actuators at room temperature and with 20% duty cycle. All our B10 lifetime estimates are based on using soft start/stop when controlling the actuators.

Understanding the calculator

When calculating the B10 life, the calculator needs the following input:

Fixed load

  • Maximum load of the actuator. This value can be found on the label under Max Load (see image)
  • The rated voltage. This value can be found on the label under Power Rate
  • The actual stroke used is the travel distance of the application – not the full stroke of the actuator

Varying load

  • Maximum load of the actuator. This value can be found on the label under Max Load (see image)
  • The rated voltage. This value can be found on the label under Power Rate
  • Travel distance is the stroke travelled at a given load
