AC Servo Type Belt Drive Products
The AC servo version of the LEFB slider features an AC servo motor instead of a DC version. The AC servo motor enables higher speed and acceleration, as well as a size 40 model not available in a DC version. Optional drivers include pulse input and various communication protocols including Ethernet. Encoders range from 17 to 22-bit resolution, depending on motor selection.
LEFB, Electric Actuator, Belt Slider, AC Servo Motor
The LEFB slider features a load mounting platform above a belt drive. A flexible seal band permits platform travel while preventing foreign matter from entering the drive. Slider advantages include a low profile height and shorter length than a rod with equivalent stroke. Belt drives allow longer strokes and higher speeds than ball screw drives. The LEFB motor can be top or bottom mounted. This model is fitted with an AC servo motor with incremental or absolute encoder. Optional drivers include pulse input and various communication protocols including Ethernet.
