Rotary actuators

  • 10-Jan-2011 03:39 EST

Exlar’s SLM and SLG rotary actuators meet application requirements for use in hazardous environments. Offering the company's brushless servo motor and gearmotor technology for high torque-to-size ratio, the actuators perform in locations where flammable gases or vapors may be present and are suited for operating quarter- or multiturn valves or shaft drive dampers on applications including ball and butterfly valves and fuel skids. Directly coupled shaft to shaft, actuators eliminate mechanisms needed by the linear motion of pneumatics. Exlar’s T-Lam segmented lamination stator technology offers individual segment phase wiring and coercive strength magnets to provide continuous modulating service. The Class I, Division 2 rotary actuators are also available with resolver feedback and handwheel options. Additional features include high load bearing design and integrated armature for SLG models, as well as multiple frame size options and speeds for SLM.
