I/O™ brochure

With the game-changing flexibility of a universal LINAK I/O interface, bringing innovative actuator ideas to life is simpler and more agile.

I have powered the actuator, but it does not show up on the device list in Actuator Connect™?

The Bluetooth® Low Energy antenna is mounted on the PCB inside the aluminium housing of the actuator. The housing reduces the signal strength significantly and it is therefore important to also plug in the signal cable. The signal cable has a dedicated wire to boost the Bluetooth signal and if this is not plugged in you will have trouble connecting to the actuator in Actuator Connect.

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.

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.

Electric linear actuators LA20 inline, LA14 with low built-in dimensions, LA40 with quick release, heavy-duty LA36, and lifting columns LC3 and DL19 IC.

What is an electric 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, as we do at LINAK, or the movement could be powered by hydraulics and pneumatics.

However, 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.

LINAK business areas for electric linear actuators

What is an electric linear actuator used for?

Electric linear actuators are used in everything from private homes, the offices where we work, all areas of a hospitals, in production in factories, to farming equipment, and many other places. LINAK electric actuators create adjustment in both desks, kitchens, beds, and couches, as well as hospital beds, patient lifts, surgery tables among others in for example hospitals and medical centres.

Electric linear actuators can also replace hydraulic and pneumatic solutions in industrial and rugged environments – for example those found in agriculture, construction, and in industrial automation equipment.

Why use an electric 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.
