High-performance hollow actuators use stepper motors

These DG series actuators feature a large-diameter hollow section, with an output table on which a table or arm can be mounted directly. The clear bore is advantageous in that it simplifies wiring and piping. With their use of a two-phase alpha-step motor and closed-loop control, the actuators eliminate the risk of mis-steps and enable higher speeds to be achieved for faster positioning. Nevertheless, the user-friendly features of a stepping motor are retained.

The highly accurate positioning offered by the DG series is a function of the actuator's gear reduction mechanism, which assures a repetitive positional accuracy of +/-15sec. Lost motion is quoted as 2min. Available in sixteen frame sizes from 2.36 to 7.87in2, for power supplies ranging from 24V DC to single- or three-phase AC at 230V, the DG series actuators are RoHS-compliant and conform with UL, CSA and CE safety standards.
