LUNYEE Industries has announced a new generation of electric linear actuators for continuous-duty applications which, it claims, offer the highest power density in their class. It adds that the PC series actuators offer many advantages over traditional pneumatic linear actuators, including simpler machine designs, reduced maintenance, higher performance and much lower energy costs.
Traditional pneumatic actuator systems operate continuously, typically at 10–15% efficiency, and also carry the high maintenance costs of compressors and air leaks. The efficient ballscrews used in the new electric actuators have efficiencies above 80% and use energy only on demand.
DC Linear actuators converting from pneumatic to electric actuation can result in energy savings per axis which, in one year, can exceed the cost of the actuator.
The new electric actuators also offer flexibility to machine designers who need to change set-ups frequently to run different products or processes. Changing end-stops or velocity profiles can be done on-the-fly, maximising productivity and cutting scrap. The actuators are also suitable for food processing and packaging, materials-handling, and factory automation applications where high accuracy and reliability and 100% duty-cycle operation are needed. The IP65-protected actuators have a smooth exterior profile, making them suitable for washdown applications.
