NEMA 14 Closed Loop Stepper Motor with Hollow Shaft

Engineered for high precision and reliability, our NEMA 14 closed loop stepper motor combines the simplicity of a stepper with the accuracy of a servo. The hollow shaft design allows for easy passage of cables or tubing, making it perfect for compact automation systems, 3D printers, CNC routers, and robotic arms.

Key Features & Benefits

• Closed-Loop Precision: Integrated 2500 PPR photoelectric encoder ensures accurate positioning and eliminates step loss.
• Hollow Shaft Design (28/35mm): Facilitates neat cable management and reduces overall system footprint.
• Customizable Drive Solution: Tailor the performance to your needs; pre-configured to work with our SSS2D4020A driver.
• Robust Construction: Class B insulation and high insulation resistance (100MΩ min) ensure durability in demanding environments.
