Compact Linear Actuators

.
DRLII Series Compact Linear Actuators

Compact Linear Actuators - DRLII Series

The DRLII 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. Strokes from 25 mm (0.98 in.) up to 50 mm (1.97 in.) depending on frame size.

High Positioning Accuracy

The ball screw nut is linked with the hollow rotor. Through the coupling rigidity and other aspects of parts combination, the impact of backlash has been minimized achieving high-precision positioning.

Actuator Positioning Accuracy

Significantly Reduced Time Required for Design

The compact body houses the entire linear-motion mechanism. The use of conventional internally-produce parts is no longer required, thus reducing the time for equipment design and parts selection. Moreover, this reduces the time required for assembly and increases your production efficiency.

Compact Linear Actuator Parts

Reliable Design and Structure

The DRLII Series features a structure in which the rotor is hollowed out and the ball screw is stored inside. The rotation of the hollow rotor rotates the ball screw nut and by setting up an anti-spin mechanism* on the tip of the ball screw, the ball screw shaft is moved in a linear manner.

Because the ball screw shaft is stored in the hollow rotor section, the maximum stroke is secured with the shortest overall length. Also, a large bore bearing is positioned on the outer circumference of the ball screw nut in order to directly receive the large thrust loads generated in linear motion.

Compact Linear Actuator Design

*Not necessary for the guide type.

Stops Immediately Without Vibration

The DRLII Series compact linear actuators use stepper motors. Because this is a stepper motor, the positioning precision per step is high and the motor can be moved forward and back accurately.

Also, since the fine movement of the shaft (called hunting) does not occur when stopping, the stop position can be held correctly.

Precise Stopping

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 DRLII ground ball screw type achieves high reliability by maximizing the performance of a 0.36°/0.72° 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 (0.36°) and Standard (0.72°) 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.

*Ground Ball Screw Type Only

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.
