NEMA 17 Dual Shaft Stepper Motor Assembly for Precision Motion

This NEMA 17 dual shaft stepper motor integrates two stators into one compact frame,
forming a Parallel Stepper Motor Assembly that delivers high torque, precision, and reliability.
Designed for advanced motion control systems, the Dual-Stator Stepper Motor provides
balanced performance with torque outputs of 0.25Nm (35.40 oz·in) and 0.17Nm (24.07 oz·in).

Features

• High-torque dual-shaft design with two synchronized NEMA 17 motors.
• Compact modular frame for easy integration into automation and robotics.
• Precision 1.8° step angle ensuring smooth and accurate motion.
• Compatible with various motor dual shaft and parallel stepper motors assemblies.
• Stable performance under 12–24V DC supply and low heating characteristics.

Applications

• 3D printers and automation systems
• Dual-axis CNC equipment
• Modular motion control devices
• SMT feeding mechanisms
• Custom dual-stator stepper motor assemblies
