Applications > High Precision Positioning

Advanced Positioning Applications

Advanced positioning applications require encoder feedback to ensure the motor accurately reaches and maintains its commanded position. Oriental Motor’s AZ Series αSTEP Hybrid Step-Servo Motors enable advanced closed-loop motion control by combining our patented Keep-in-Step technology, low-loss laminations, and a multi-turn battery-less mechanical absolute encoder in a single system, delivering servo-like performance without the servo complexity. Common applications include index tables, start/stop conveyors, and robotic arms that require a higher level of precision, speed, and reliability.

Product Selection by Application

Index Table / Carousel

Indexing a batch of samples in a carousel requires high inertia handling capability, high accuracy positioning, and low vibration performance.

XYZ Gantry / Autosampler

Positioning an XYZ gantry system reliably improves efficiency for filling operations.

Wafer Pin Lifter

Lifting and lowering silicon wafers require precise and smooth motion in a compact design. Precise handling minimizes tilting of the wafer, causing scratches or other damage to the wafers.

Wafer Handling Machine

Handling wafer presents unique challenges like moving high inertial loads precisely and delicately.

Chemical Mechanical Polishing (CMP)

Precise control of the swing arm position and polishing pad speed are critical for polishing wafers.

Wafer Loading / Unloading

Wafer handling requires extreme accuracy and delicate movements while closed-loop feedback provides peace of mind.

Spraying / Cleaning Device (Nozzle) Swing Arm

Cleaning tool application requires high torque, precise positioning, and the ability to control torque.

CMP CUP Lifting

Lifting mechanism in semiconductor tool requires high torque and synchronous motion in a small footprint.

Capping

For applications such as pressure sensitive stamping, pressing, capping or screwing mechanisms, a torque limit function can be useful.

Label Applicator

The precision, controllability, and efficiency of our products are well-suited for packaging, sealing, and winding applications.
