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.
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.
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.
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.
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.
LES and LESH integrate a work table, linear guide and a motor driven linear ball screw. The work table offers top and front load mounting surfaces. Underneath, the linear guide maintains positional accuracy and supports moment loading.
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.
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.
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 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.
