<Discription>

The Autonics 02K-S523 is an ultra-compact, high-precision 5-phase stepper motor designed for applications requiring minimal installation depth. Featuring a miniature 24mm frame size, it is the shortest model in the 24mm series (shorter than the 04K series), with a motor length of just 30.5 mm. It delivers a maximum stop torque of 1.8 kgf·cm (0.018 N·m). The Single Shaft configuration minimizes the overall footprint, making it the ideal choice for extremely tight spaces where rear-shaft accessories are not required. Operating at a rated current of 0.75 A/Phase, it ensures energy-efficient performance for miniature automation equipment.

Key Features

• Ultra-Compact & Thin: With a 24mm square frame and a short body length of 30.5mm, it offers the most space-saving profile in the series.

• Single Shaft Design: The standard single shaft configuration allows for a minimized installation depth compared to dual-shaft models.

• High Precision: Offers a basic step angle of 0.72° (Full step) and 0.36° (Half step) for fine positioning accuracy.

• Rated Current 0.75 A/Phase: Optimized for energy efficiency in small-scale devices.

• Low Vibration: The 5-phase design ensures smoother rotation and lower vibration compared to standard 2-phase motors.
