<Discription>

The Autonics A140K-G599W-G5 is a high-performance 5-phase stepper motor integrated with a 1:5 reduction gear and an electromagnetic brake. Designed for heavy-duty applications, it delivers a powerful torque of 140 kgf·cm (14 N·m) while ensuring reliable position holding during power outages, making it ideal for vertical lifting systems.

Key Features:

Powerful Torque (1:5 Gear): The built-in 1:5 reduction gear amplifies the torque to 140 kgf·cm (14 N·m), allowing it to drive heavy loads with ease.

Built-in Safety Brake: Equipped with a Power-off Locking (B-type) electromagnetic brake. It instantly locks the shaft when power is cut, preventing load drops in vertical applications (Z-axis).

High Precision: Features a high-accuracy gear mechanism with minimized backlash (±15' / 0.25°), ensuring precise positioning even under high loads.

Large Frame (85mm): The robust 85mm frame size provides structural stability and high thermal efficiency for industrial use.

All-in-One Design: Combines the motor, reduction gear, and brake into a single compact unit, saving installation space and simplifying wiring.
