Hollow Rotary Actuators
DG Series
The DG Series is an actuator featuring a hollow output table that allows large-inertia discs and arms to be installed directly.
The coverage of applications has widened with the addition of models with a frame size of 200 mm and permissible torque of 50 N.m.
High Output, High Rigidity, High Accuracy Positioning without Backlash
The hollow output table is integrated with a high rigidity cross-roller bearing*. *Except for DG60
This structure improves permissible thrust load and moment load while maintaining high torque.
- Non-backlash
- Repetitive positioning accuracy: ±15 sec
- Lost Motion: 2 min
Less Hassle with Direct Coupling
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 parts, adjusting the belt tension, etc., compared to when mechanical parts such as belt and pulley are used for installation.
Home-Sensor Set is Available as an Accessory
The sensor set comes with all the parts required for the return to home operation, meaning you will spend less time designing, fabricating and procuring parts relating to sensor installation.
Simple Wiring and Piping
The diameter of the driven gear has been increased with the use of a single-stage reduction gear mechanism, resulting in a hollow hole (through-hole) of sufficiently large diameter with respect to frame size. This helps reduce the complexity of wiring and piping, thus simplifying your equipment design.
Supporting Sudden Load Fluctuation
Adopting a closed loop 
stepping motor designed to maintain synchronism, 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 synchronism is about to be lost, closed-loop control is implemented immediately. With the DG Series, you can also enjoy greater reliability, because the positioning completion signal and position detection function can be used to check the actuator condition.
Stable operation can be achieved without adjustment, even when your equipment is subject to load fluctuation.
