Features | Hollow Rotary Actuator DH Series

Hollowness Simplifies Piping and Wiring at the End of the Equipment

This actuator is a 5-phase stepper motor with a hollow flange. Air piping, wiring, and rays are passed through the hollow section, contributing to a simplified design, smaller size, and lighter weight at the end of the equipment.

Flange Mount Contributes to the Reduction of Parts Around Moving Parts

The load can be directly mounted to the hollow flange. This contributes to reducing the number of parts around moving parts.

    Example: Using DHM42PAK

Some of the conventional parts have been eliminated, so the time required for equipment design and product selection is shortened.
Furthermore, the number of man-hours required for assembly and the adjustment of installation accuracy can be reduced, contributing to higher productivity.

Advantages of Using the Equipment

  • Reduction of Design Time
  • Lower Parts Cost
  • Reduction of Assembly Man-Hours
  • Reduction of Accuracy Adjustment Time
  • Reduction of Maintenance Time

Highly Accurate Positioning

Equipped with a 5-phase stepper motor, it can perform highly accurate positioning and fine operations stably and repeatedly. Microstep drive and smooth drive function in combination with the CVD driver enable smooth operation with low speed vibration. The hollow flange does not use transmission mechanisms such as couplings or belts, so accuracy is not affected by component rigidity or combination errors.
