<Discription>

The Autonics 04K-S525W is an ultra-compact 5-phase stepper motor designed for precision applications in tight spaces. Featuring a miniature 24mm frame size, it delivers a maximum holding torque of 0.28 kgf·cm (0.028 N·m). This model operates at a rated current of 0.75 A/Phase, making it highly energy-efficient. The Dual Shaft (W) configuration allows for flexible mounting options or the attachment of small accessories (like encoders or dampers) to the rear shaft, making it ideal for miniature medical devices, optical equipment, and precision instruments.

Key Features

• Ultra-Compact Design: The 24mm square frame is the smallest in the series, perfect for applications where weight and space are critical constraints.

• Dual Shaft (W): Features a rear shaft extension for mounting auxiliary devices such as feedback encoders or vibration dampers.

• Precision Control: Offers high resolution with a basic step angle of 0.72° (Full step) and 0.36° (Half step).

• Rated Current 0.75 A/Phase: Optimized for low power consumption while maintaining precise positioning control.

• Low Vibration: The 5-phase design inherently reduces vibration compared to standard 2-phase motors, crucial for delicate optical or medical applications.
