57CME23 Closed-loop Stepper motor Nema23 Shaft 21mm 8mm 2.3Nm 4A/5A 1.8° with Encoder for CNC

57CME23 57 NEMA23 Closed-Loop Stepper Motor
 
Product Overview
The 57CME23 is a high-performance NEMA 23 closed-loop stepper motor (also known as a hybrid servo motor). It features a 1.8° step angle, 2.3N·m holding torque, and a built-in 1000CPR optical encoder for real-time position feedback. This eliminates step loss, significantly improves motion accuracy, and delivers smoother, quieter operation with lower heat generation compared to traditional open-loop stepper motors. It is widely used in automation equipment requiring high precision and reliability.
