<Discription>

The Autonics A8K-M566-B is a reliable 5-phase stepper motor equipped with a built-in electromagnetic brake. Featuring a standard 60mm frame size, it delivers a maximum stop torque of 8.3 kgf·cm (0.83 N·m). This "M" type model operates at a rated current of 1.4 A/Phase, offering balanced performance for various industrial drivers. The integrated B-type brake ensures safety by locking the shaft when power is cut (Power OFF = Lock), making it an ideal choice for vertical applications or systems requiring position retention during emergency stops.

Key Features:

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

Built-in Safety Brake: Features a normally closed electromagnetic brake that holds the position when power is turned off, preventing load drops.

Rated Current 1.4 A/Phase: Designed for 1.4 A/Phase operation ("M" Type), ensuring compatibility with standard drivers.

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.
