Compact Linear Actuators

.
DRL Series

Compact Linear Actuators - DRL Series

The DRL Series of compact linear motion actuators uses a 0.36° or 0.72° stepper motor which incorporates a rolled or ground ball screw. Available with a guide or no guide and combined with a 24 VDC microstepping drivers for extremely precise positioning.

Compact Design and High Position Accuracy

The compact and lightweight body houses the rotating components as well as the linear motion mechanism of the stepper motor. The DRL Series helps to achieve a significant reduction in the size of your equipment and system.

To meet the user's requirements for higher positioning accuracy, a ground ball screw model is available [repetitive positioning accuracy: ±0.0002 in. (±0.005 mm)].

Quick Lead Time

Reliable Design and Structure

The hollow rotor shaft incorporates large bore bearings for the direct handling of thrust loads. Minimizing the number of parts involved in linear conversion results in higher reliability.

Construction

The figure above shows a structure of the standard type (rolled ball screw shaft). A set collar (on the screw shaft), which prevents the screw shaft from retracting completely into the case, is being ommited in this figure.

Significantly Fewer Parts

The compact body houses the entire linear-motion mechanism, with some of the conventional parts eliminated for a more streamlined structure. This substantially reduces the man-hours required for design and assembly of our equipment, so you will enjoy higher production efficiency.

Design

Wide Range of Variations

Ground Ball Screw or Rolled Ball Screw

Ground Ball Screw
Ideal for applications where high positioning accuracy and low vibration are required, such as optical devices and semiconductor systems that use fine-feed pitches. The DRL ground ball screw type achieves high reliability by maximizing the performance of a 5-phase stepper motor.

Rolled Ball Screw
Ideal for general positioning applications where reliability and ease of use are given priority. It combines the superior thrust and resolution of the ground ball screw type with greater ease of use.

Standard or Guide Type

The DRL Series actuators are available in standard or guide types. If you choose standard type, you must provide an external anti-spin mechanism.

High Resolution and Standard Type Motors

The high-resolution motors achieve high accuracy and reliability based on Oriental motor's latest precision machining technology. The motor resolution is increased to double the level of a standard model to reduce the displacement angle against torque, thereby achieving high position accuracy. Frame sizes of 1.10 in. (28 mm), 1.65 in. (42 mm) and 2.36 in. (60 mm) are available.

In fine-feed operations by microsteps, the actuator will not operate until the initial motor torque exceeds the friction load. The high-resolution motor, with its high output torque, allows the torque to pick up quickly and thereby ensures smooth operation even with fine-feed.

Positioning Error

Additional Features

The standard type and guide types are available with an electromagnetic brake and/or adjusting knob as additional functions.

Adjusting Knob
The load position can be adjusted manually when the power is cut off. This function is useful during servicing of the equipment.

Adjustment Knob

Electromagnetic Brake
The load position can be held when the power is cut off. Since the work will not fall in case of power failure or disconnection, you can safely use equipment in which the work moves vertically.

Compact DC Input Board Driver

Driver

Compact DC Input Board Driver Meeting the Space-Saving Needs

The compact, lightweight driver implements microstep drive. The new IC provides a wide range of functions, including the following:

  • Smooth Drive Function
  • 1-pulse/2-pulse input mode switching
  • 25 microstep drive resolutions
  • Power LED
  • Photocoupler input
  • Connector with lock (by MOLEX)
  • Conforming to major safety standards

 

Compact Microstep Driver

The microstep drive system allows you to set high resolutions up to 1/250 of the basic resolution of the actuator. This function is effective in meeting your low-vibration/low-noise operation needs at low speeds. The high-performance driver is also compact and lightweight, achieving a reduction of approximately 47% in size compared to a conventional microstep driver.

Smooth Drive

Smooth Drive Function

The Smooth Drive Function automatically controls the motor's microstep drive operation at the same travel and speed in the full-step mode, without the operator having to change the pulse input settings. This function is especially useful when used in the full-step or half-step mode.

Driver Lead Wire Set

Driver Lead Wire Set

These lead wires are used to connect the driver with the actuator, controller and DC power supply. The driver lead wire set includes three lead wire/connector assemblies (for actuator, power supply, input/output signal). One end of the lead wire is crimped therefore crimping is not necessary.
