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.

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.

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 stepping 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.

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.

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

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.

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

Longer Stroke
The ground ball screw type and rolled ball screw type with standard motor [frame size 1.10 in. (28 mm), 1.65 in. (42 mm) and 2.36 in. (60 mm)] are now available with longer strokes. The longer stroke models of the DRL Series extends the sphere of applications.

Available Stroke Lengths:

• 1.10 in. frame size =
  1.18 in. or 2.36 in. stroke
• 1.65 in. frame size =
  1.57 in. or 3.94 in. stroke
• 2.36 in. frame size =
  1.97 in. or 3.94 in. stroke

Compact, Lightweight Microstep Driver

The compact, DC input board level driver implements microstep drive and 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 more compact and lightweight, achieving a reduction of approximately 47% in size compared to conventional microstep drives.

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.
