<Discription>

The Autonics A21K-M596W is a robust 5-phase stepper motor featuring a Dual Shaft (W) configuration. Designed with a large 85mm frame size, it delivers a reliable maximum stop torque of 21 kgf-cm (2.1 N-m). This "M" type model operates at a rated current of 1.4 A/Phase, making it compatible with drivers requiring lower current specifications compared to the "G" type. The dual shaft design enhances versatility by allowing the attachment of auxiliary devices such as vibration dampers, encoders, or manual handwheels to the rear shaft, making it adaptable for various industrial automation needs.

Key Features:

High Torque Output: Delivers a maximum stop torque of 21 kgf-cm (2.1 N-m), providing reliable force for various industrial loads.

Dual Shaft Design (W): Equipped with shafts extending from both the front and rear, enabling the connection of accessories like dampers or encoders.

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