<Discription>

The Autonics A8K-S566-B is a precise 5-phase stepper motor featuring a built-in electromagnetic brake. Designed with a standard 60mm frame size, it delivers a maximum stop torque of 8.3 kgf·cm (0.83 N·m). This "S" type model operates at a low rated current of 0.75 A/Phase, making it suitable for drivers designed for lower current output or energy-efficient applications. The integrated B-type brake provides reliable position holding during power outages (Power OFF = Lock), ensuring safety in vertical drive systems.

Key Features

• Reliable Torque Output: Delivers a maximum stop torque of 8.3 kgf·cm (0.83 N·m), providing sufficient power for standard industrial loads.

• Built-in Safety Brake: Equipped with a normally closed electromagnetic brake that locks the shaft when power is turned off, preventing load drops.

• Rated Current 0.75 A/Phase: Designed for 0.75 A/Phase operation ("S" Type), distinguishing it from higher current "M" or "G" type models.

• Standard 60mm Frame: The 60mm square flange ensures easy installation and structural stability.

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