Synchronization option for Thomson linear actuators

Thomson Industries Inc., a manufacturer of linear motion control solutions, has announced the availability of an enhanced synchronization option for its Electrak HD smart electric linear actuator. The latest iteration of this control option implements position-based synchronization within the actuators’ onboard electronics for  motion control applications requiring instant load balancing of multiple Electrak HD units.

“We worked closely with industrial equipment builders who need dynamic and reliable load synchronization and redesigned our controls to meet their demands. By incorporating advanced position sensing and communication capabilities, we have streamlined the process of synchronizing multiple actuators. This enhancement helps users achieve increased efficiency, strength and safety in heavy duty applications,” said Violet Urban, product manager at Thomson.

The company said the synchronization option can support up to eight Electrak HD actuators that connect in real time across a CANbus network, ensuring operation in harmony. A constant heartbeat signal in each actuator maintains position awareness for all units. If one actuator senses a heavier load, it will signal to the others to slow their speed to maintain the same position. Only in the instance of a fault (loss of communication or power, or excessive voltage or temperature) on one or more of the actuators will the entire system shut down. This instant communication prevents binding or buckling, enhancing reliability and safety.

The Electrak HD embeds all synchronization functionality into its built-in electronics, making the system plug and play. All mounted and wired actuators can begin synchronizing immediately following installation.

The Electrak HD can handle loads of up to 16 kN. The synchronizing option is beneficial for many applications that are challenged with awkward or unbalanced loads, including: work platforms, where the system must maintain a level surface as workers change position; and automated material handling, where multiple actuators help move products smoothly along conveyor belts or on an automated guided vehicle; and solar panels, where multiple actuators help raise, lower and tilt heavy loads in sync and protect them from structural damage.

The enhanced synchronization option is available immediately when ordering the Thomson Electrak HD.
