Motorized Actuators
Hollow Rotary Actuators

DG Series

dg_image
A hollow rotary actuator featuring a hollow output table that allows large-inertia tables or arms to be installed directly.
The actuator uses an αSTEP motor adopting closed loop control.
Highly accurate positioning can be performed while keeping the user-friendly features of a stepping motor intact.
Features
dg_01

Direct Coupling for Higher Reliability

Equipment tables and arms can be installed directly on the output table.
This saves you the hassle and cost of designing an installation mechanism, arranging necessary mechanism parts, adjusting the belt tension, etc., when mechanical components such as a belt and pulley are used for installation.


dg_02

High Power, High Rigidity

The hollow output table is integrated with a high rigidity crossroller bearing✽.
This structure improves permissible thrust load and moment load while maintaining high torque.
✽ Except for the DG60


High Positioning Accuracy with Non-Backlash

・ Non-Backlash
・ Repetitive Positioning Accuracy ±15sec
・ Lost Motion 2 arc minutes


Large-Diameter, Hollow Output Table Makes Simple Wiring and Piping Possible

The large diameter hollow hole (through-hole) helps reduce the complexity of wiring and piping, thus simplifying your equipment design.

Supporting Sudden Load Fluctuation and Rapid Acceleration

Adopting the αSTEP stepping motor, the DG Series actuator eliminates the need for tuning to prevent hunting upon sudden load fluctuation or rapid acceleration.
A built-in rotor position detection sensor constantly monitors the motor speed and rotations.
If overload is about to occur, closed-loop control is implemented immediately.
With this series, you can also enjoy greater reliability because the positioning completion signal and position detection function can be used to check the actuator condition.

“Home-Sensor Set” is Available as an Accessory

Since the sensor set comes with all the parts required for the return-to-home operation, you will spend less time designing, fabricating and procuring parts relating to sensor installation.


■Selectable Drivers by System


Pulse Input

The motor can be controlled using a pulse generator provided by the customer.
For the absolute type, please contact the nearest Oriental Motor sales office.


Built-In Controller (Stored data)

Direct control can be done from the programmable controller I/O with the built-in controller function. There is space saving because a controller is not necessary.
For the absolute type, please contact the nearest Oriental Motor sales office.


Network Compatible

CC-Link, DeviceNet, MECHATROLINK
