<Discription>

The Autonics A4K-S564W is a compact 5-phase stepper motor featuring a Dual Shaft (W) configuration. As the most compact model in the 60mm frame series, it offers a maximum stop torque of 4.2 kgf·cm (0.42 N·m). This "S" type model operates at a rated current of 0.75 A/Phase, making it an energy-efficient option suitable for drivers designed for lower current output compared to "M" type models. The dual shaft design enhances versatility by allowing the attachment of auxiliary devices such as vibration dampers, encoders, or manual handwheels to the rear shaft, making it ideal for applications where space is limited but rear-shaft functionality is required.

Key Features

• Compact Torque Output: Delivers a maximum stop torque of 4.2 kgf·cm (0.42 N·m), optimized for lighter loads within a stable 60mm frame structure.

• Dual Shaft Design (W): Equipped with shafts extending from both the front and rear, enabling the connection of accessories like dampers or encoders.

• Rated Current 0.75 A/Phase: Designed for 0.75 A/Phase operation ("S" Type), ideal for low-current drivers and energy-sensitive applications.

• Standard 60mm Frame: Matches the mounting dimensions of larger models (A8K/A16K) but features a shorter body length for space-saving installation.

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