<Discription>

The Autonics A15K-S545-G7.2 is a compact 5-phase stepper motor featuring a built-in 1:7.2 reduction gear and a standard Single Shaft configuration. Despite its small 42mm frame size, this model delivers a reliable torque of 15 kgf-cm (1.5 N-m). It operates at a rated current of 0.75 A/Phase ("S" Type). The single-shaft design allows for a minimized installation depth, making it ideal for space-constrained industrial applications requiring precise low-speed torque without the need for rear shaft access.

Key Features:

High Torque (1:7.2 Ratio): Integrated with a 1:7.2 reduction gear to amplify torque output to 15 kgf-cm (1.5 N-m).

Compact 42mm Frame: The small 42mm square flange size allows for installation in tight spaces where larger motors cannot fit.

Single Shaft Design: The standard single shaft configuration offers a minimized installation footprint compared to dual-shaft models.

Precision Control: Features a high-accuracy gear mechanism with backlash of +/- 35 arcmin (0.58 degrees).

Smooth Motion: Supports a basic step angle of 0.1 degrees (Full step) and 0.05 degrees (Half step) via the 1:7.2 reduction ratio.
