Electric Actuators

Electric Actuators Hero Image

Electric actuators offer distinct advantages over their pneumatic counterparts. Acceleration and speed are controlled and predictable. Multiple positions are possible with high precision and repeatability.  Pushing forces can be programmed. With no need for compressed air, infrastructure and energy costs are lower. LE is SMC's current line of electric actuators, designed with a focus on easy setup and operation.  Function parameters come preset, plus an "Easy Mode" setting option allows you to be operational quickly. The LE line is available in a variety of types including: sliders, rod and guided rod, slide tables,  rotary, grippers, and miniature. Accessories include actuator controllers, and gateways.

Sliders

Sliders

Rodless type electric actuator features a load mounting platform situated above a ball screw drive or belt drive. Ball screw type advantages are better positioning repeatability than belt drives.  Belt drive  provides a more economical offering.


AC Servo Sliders

AC Servo Sliders

Similar to the Slider type except utilizes an AC servo motor instead of a DC type.  The AC servo motor enables higher speed and acceleration, as well as improved vertical load capability. The drivers are  pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.


Rod and Guided Rod

Rod and Guided Rod

The rod type electric actuator has a familiar rod cylinder form suitable for push, pull, lift and press applications. The guide rod type includes rods to counter rotational forces instead of the drive and  motor, and also resist shock and sustained lateral loads.


AC Servo Rod Type

AC Servo Rod

Similar to the Rod and Guided Rod type except utilizes an AC servo motor instead of a DC type.  The AC servo motor enables higher speed and acceleration, as well as improved vertical load capability.  The  drivers are pulse input type, with both incremental and absolute encoder options and 17- or 18-bit resolution.


Slide Table

Slide Table

The slide table electric actuator combines a motor and ball screw drive, worktable, and linear guide in compact body. Body orientations include basic, symmetrical, and inline mounted motor


Rotary

Rotary

Rotary electric actuators feature a rotating worktable positioned above an enclosure for the motor and drivetrain. Three different motor/table sizes are available, with each size offering a basic and high  torque variation. Additionally, each size offers four rotating angle options, including 90°, 180°, 310 / 320°, and continuously rotating.


Grippers

Grippers

The family of electric grippers includes three series fitted with two fingers. Dust covers, low profile fingers and long stroke options are some of the series differentials. There is also a 3 finger type with  the ability to hold round work pieces.  Benefits of electric grippers include adjustable gripping forces, a drop prevention function, and gauging capability for recognizing different dimensions and outputting  length measurements.


Miniature

Miniature

The LEP family of actuators includes a rod type and a slide table type. Each is built around the same motors, drives and bodies. Each model is lightweight, less than 1-1/2 lb, and compact enough to fit in the  palm of your hand.  The LAT3 Card Motor is about the size of a credit card and only 9mm high. Positioning repeatability is ±5 μm, with an operating rate of up to 500 cycles per minute.


Controllers and Drivers

Controllers and Drivers

Controllers and drivers needed for our electric actuator family.  You will find step motor, servo motor and card motor controllers as well as 24VDC Fieldbus gateway units and AC servo drivers.
