<Discription>

The Autonics A1K-S543 is a highly compact 5-phase stepper motor designed for space-critical industrial applications. As the most compact model in the 42mm frame series, it delivers a precise maximum stop torque of 1.3 kgf·cm (0.13 N·m). This "S" type model operates at a rated current of 0.75 A/Phase, making it an energy-efficient choice ideal for small equipment where minimizing heat generation is a priority. The standard Single Shaft configuration allows for a minimized installation depth, making it perfect for systems requiring precise motion control in an extremely small form factor without the need for rear shaft accessories.

Key Features

• Compact Torque Output: Delivers a maximum stop torque of 1.3 kgf·cm (0.13 N·m), providing precise holding force in a small 42mm footprint.

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

• Rated Current 0.75 A/Phase: Designed for 0.75 A/Phase operation ("S" Type), compatible with standard drivers for 42mm motors.

• Standard 42mm Frame: The 42mm square flange is compatible with NEMA 17 mounting standards, suitable for compact machinery.

• Precision 5-Phase Control: Supports a basic step angle of 0.72° (Full step) and 0.36° (Half step) for smooth and accurate positioning.
