SANMOTION Model No. PB Closed-Loop Stepping System, Stepper Motor & Stepper Driver

The SANMOTION PB is an innovative closed-loop stepper system that blends the simplicity of stepper motors with the reliability of servo motors. With its unique control method, it completely eliminates the step-out common in traditional stepper motors and the hunting often observed in servo motors. It minimizes micro-vibrations during stoppage, significantly shortens positioning time in short-stroke operations, and provides high torque at low speeds.
The system also reduces motor heat through optimized current supply and is equipped with a high-speed EtherCAT communication interface for enhanced control and energy efficiency.
