Orientalmotor DR Series Compact Electric Cylinder

Made in Japan
Manufacturer: ORIENTAL MOTOR CO., LTD.
Model: DR Series

Major features

αSTEP and ball screw integrated structure

High-precision positioning is achieved by combining the high-precision αSTEP with a ball screw.

By integrating the hollow rotor and ball screw nut without using connecting parts such as couplings, the effects of backlash caused by component rigidity and combination are reduced.

DR Series

Two types of drive ball screws

Drive Ball Screw precision Rolling
Repeated positioning accuracy ±0.003mm ±0.01mm
Minimum Movement 0.001mm

Achieves high payload and high speed operation *

Lead 1mm 2.5mm
Payload capacity Horizontal 4kg 4kg
vertical 4kg 2kg
maximum speed 40mm/s 100mm/s
  • *The specifications in the table are for a table type with a mounting angle of 28 mm.

We have prepared a support tool that can calculate the approximate positioning time for applicable our electric actuator products according to the “model” and “operating conditions.”

Equipped with αSTEP AZ series drive motor

  • Built-in battery-less absolute sensor, constantly monitors motor position information without the need for an external sensor
  • High reliability through closed loop control
  • High efficiency reduces motor heat generation and saves energy
ABZO sensor

Stable fine feeding is possible

Equipped with αSTEP, it is possible to stably repeat minute movements one step at a time, making it ideal for fine adjustments to cameras and lenses.

DR series fine feed

Slow and smooth movement

The micro-step drive and smooth drive functions * suppress vibrations at low speeds, allowing smooth movement. Ideal for the drive shaft that steadily supplies solution from a syringe.

  • * This control automatically drives in microsteps at the same movement distance and speed as in full step without changing the pulse input settings.
DR Series: Slow and smooth

Contributes to smaller and lighter equipment

The compact body that integrates αSTEP and ball screws contributes to downsizing and space saving of equipment.
The weight reduction of the equipment tip is expected to improve design freedom.

Contributes to smaller and lighter equipment

Types and additional functions can be freely combined

Table Type

This product is equipped with a highly rigid guide that can secure a load to the cylinder.
It is easy to directly attach a load.

Table Type

Rod Type

It can be directly built into equipment due to its compact shape without guides, etc.
It can also be used as a compact thrust shaft in the load transport guide of equipment.

Rod Type

Products with additional functions such as ball screw covers and mounting plates are available

With ball screw cover

We offer products with ball screw covers for simple dust protection.

DR series ball screw cover

Mounting plate included

We offer products with mounting plates. Two types are available: a type that uses a “flange” to be mounted from the back, and a type that uses a “foot” to be mounted from the top.

DR series with mounting plate

Shorten the time it takes to start up equipment

Linear motion mechanism concentrated in a compact body

Since there is no need to manufacture parts yourself, you can reduce the time required for “designing equipment and selecting parts” and “adjusting assembly and installation precision,” which leads to more efficient equipment startup.

Example of configuration when moving the workpiece with the same stroke

Parameters required for operation are already set

Mechanical parameters such as lead and stroke are set by the ABZO sensor at the time of shipment. After purchase, they can be set in units of mm, which contributes to shortening the start-up time of the equipment.

The travel distance can be set in "mm" units (MEXE02)

No origin sensor required

Position information is mechanically managed by the ABZO sensor, so there is no need for external sensors such as origin sensors or limit sensors. This also avoids the trouble of periodic maintenance that occurs when using external sensors.

No origin sensor required, saving space
