01/27/2011


Exlar’s SLM and SLG rotary actuators are available with Class I, Division 2 Certification, meeting application requirements for use in hazardous environments. Exlar Rotary ActuatorOffering the same features as the standard models—including Exlar’s brushless servo motor and gearmotor technology, which provides the highest torque-to-size ratio available in motion control today—the SLM and SLG rotary actuators deliver reliable performance for a wide variety of motion control applications. With the Class I, Division 2 option, SLM and SLG rotary actuators provide a powerful and efficient motion control solution for use in locations where flammable gases or vapors may be present.

Exlar’s SLM and SLG rotary actuators are suited for operating quarter turn or multi turn valves or shaft drive dampers. Directly coupled shaft-to-shaft, these actuators reportedly eliminate cumbersome mechanisms needed by the linear motion of pneumatics. Operating with Exlar’s T-Lam segmented lamination stator technology, which consists of individual segment phase wiring and high coercive strength magnets—the SLM and SLG compact servo motors allegedly outperform any standard motor, providing superior, continuous modulating service. To meet application requirements, the Class I, Division 2 rotary actuators are also available with resolver feedback and handwheel options. Additional features include:

  • High load bearing design
  • Integrated armature and sungear for SLG models
  • Class I, Division 2, Groups A, B, C and D certified
  • Terminal box with NPT ports

Exlar’s SLM and SLG Class I, Division 2 rotary actuators are well-suited for many applications, such as:

  • Ball Valves
  • Butterfly Valves
  • Fuel Skids
  • Oil & Gas Upstream & Downstream
  • Power Utilities
  • Basic Weight
  • Paint Booths

The SLM Series delivers a high torque in a small package, purportedly providing superior product quality and performance. Offering multiple frame size options, including 90, 115 and 142 mm, and producing speeds up to 4000 rpm, Exlar’s SLM motors are suited for a variety of precision motion and speed applications. Feedback configurations are available for nearly any servo amplifier, providing product flexibility for application requirements.

Exlar’s UL Recognized SLG Series Integrated Gearmotors offer high power densities in a compact design. Available in two frame sizes—90 and 115 mm—the SLG Series offers 1, 2 or 3 stack lengths with single and double reductions available for varying applications. Providing a high side load bearing design and higher stiffness than bolt-on gearhead and motor designs, Exlar’s SLG motors’ unique design is helpful for applications where weight or space is at a premium.

Annual Salary Survey

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.

There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.

But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
