EAT15-1 Motorized Angular Stage
Product Introduction
The EAT15-1 Motorized Angular Stage is a precision motorized rotation and angular positioning stage designed for optical instruments, laboratory automation, precision measurement, and positioning systems.
Equipped with a stepper motor, standard RS232 interface, and 252:1 worm gear drive, the EAT15-1 provides precise ±15° angular adjustment with high positioning accuracy and repeatability. It can be combined with the CHFKZQ series motion controller for automated motion control.
The stage features a horizontal mounting surface, compact aluminum alloy construction, circular ball bearings, and a worm-drive mechanism for smooth, stable, and reliable angular positioning.

Performance Features
•   Motorized precision angular adjustment
Provides an angular range of ±15° for controlled rotational positioning.
•   Stepper motor drive
Standard stepper motor enables programmable and repeatable positioning.
•   RS232 communication
Supports connection to motion controllers for automated positioning applications.
•   High-ratio worm drive
The 252:1 worm gear transmission provides stable motion and precise angular adjustment.
•   Precision circular guide system
Circular ball bearings combined with a circular steel guide provide smooth and reliable movement.
•   Low-noise transmission
High-quality elastic coupling synchronizes the stepper motor and worm shaft while reducing transmission noise.
•   Orthogonal dual-axis capability
Two stages can be paired and stacked with the same rotation center for concentric two-axis angular adjustment.
•   Limit switch protection
Integrated limit switches facilitate positioning and protect the stage from excessive travel.
•   High load capacity
Supports loads up to 15 kg despite its compact 65 × 65 mm platform.

Working Principle
The EAT15-1 Motorized Angular Stage converts the rotational motion of its stepper motor into precise angular movement through a 252:1 worm gear transmission.
When controlled by an RS232-compatible motion controller, the stepper motor receives positioning commands and rotates the worm shaft. The worm gear then drives the angular platform through the required rotation range.
The circular ball-bearing and steel-guide structure provides smooth support during movement, while the high transmission ratio improves positioning stability. Limit switches provide travel protection and assist with positioning.
Two EAT15-1 stages can also be stacked to create a concentric two-axis angular positioning system, making the stage suitable for multi-axis optical alignment and precision positioning.
