Actuators Get Synchronized


Elektrak HD heavy duty electromechanical linear actuators now have synchronization capabilities.


Synchronization is achieved by embedding all load handling technology into a single electromechanical actuator, which is then wired in sequence with up to three other similarly equipped actuators. Designers install these wherever linear movement is needed without the need for external assemblies. Once the actuators are installed, customers synchronize them instantly by wiring them together and operating a single unit with a simple switch. During operation, system electronics detect speed changes that indicate load imbalances, thereby eliminating bouncing or other effects of imbalance. 


By using multiple actuators, synchronization increases system movement speed more efficiently. A larger load that might normally use a single, heavy load actuator, for example, could be moved faster by combining multiple, lower load actuators. Synchronization also retains all Electrak HD mechanical capabilities, including the handling of bidirectional loads of up to 10 to 16 kN (2,250 lbf) with stroke lengths up to 1,000 mm (39 in.) and accuracy of 1% of stroke from 100-1,000 mm. High-quality ball screw assemblies provide efficient current draw and support speed options up to 43.5 mm/sec (1.7 in/sec) (using the 1.7 kN [382 lbf] version). 


By expanding from 10 kN (2,250 lbs) to 16 kN and enabling that capability at stroke lengths up to 500 mm (20 in), Thomson has also set a high performance and durability benchmark for electromechanical actuators with onboard intelligence. Its minimum duty cycle of 25% among stroke lengths up to 500 mm is the highest in the industry, assuring maximum continuity of operation with minimum current draw. For 16 kN loads at those stroke lengths, Thomson also offers speed options up to at least 5 mm/s (0.197”/sec).


With enhanced functionality provided by an advanced onboard Electrak Modular Control System (EMCS) and its optional functions, the Electrak HD line offers a simpler method of control and communication, which reduces operating costs, requires less space and simplifies setup and installation. Optional out-of-the-box J1939 CAN bus communication enables control and monitoring, while optional low-level switching, end-of-stroke indication output, choice of analog or digital feedback, and a customer control interface provide additional versatility.


Contributing to durability in high-load operations are unrivaled environmental resistance ratings of IP69K static, IP67 static and IP66 dynamic. Even with high loads, the actuators will operate in temperatures ranging from -40 to +85°C (-40 to +185°F), can withstand salt spray for 500 hours, and are CE, RoHS and REACH (EU) compliant. 


Likewise, when operating at loads of up to 16 kN, Thomson still delivers unique functionality such as manual override, anti-rotation features, integral thermal overload protection, load lock in case of nut overload failure, a high-quality ball screw, and flexible front and rear clevis options. Higher load options also comply with Thomson test plan requirements, which certify optimal performance regardless of the severity of the application.
