<Discription>

The Autonics A21K-G596-B is a reliable 5-phase stepper motor featuring a built-in electromagnetic brake. Designed with a robust 85mm frame size, it delivers a maximum stop torque of 21 kgf-cm (2.1 N-m). This "G" type model operates at a rated current of 2.8 A/Phase. The integrated B-type brake provides reliable position holding during power outages (Power OFF = Lock), making it essential for vertical drive systems and safety-critical equipment.

Key Features:

High Torque Output: Delivers a maximum stop torque of 21 kgf-cm (2.1 N-m), suitable for reliable motion control in industrial applications.

Built-in Safety Brake: Equipped with a B-type electromagnetic brake that locks the shaft when power is turned off, preventing load drops in vertical applications.

Rated Current 2.8 A/Phase: Designed for 2.8 A/Phase operation ("G" Type), ensuring high-output performance compatible with standard drivers.

Robust 85mm Frame: The large 85mm square flange provides excellent structural stability and durability.

Precision 5-Phase Control: Offers high resolution with a basic step angle of 0.72 degrees (Full step) and 0.36 degrees (Half step).
