PB Closed-Loop Stepping Systems

SANMOTION Model PB Closed-Loop Stepping Systems combine the ease-of-use functions of stepping motors and the reliability of servo motors. A position-detecting encoder mounted on the stepping motor delivers feedback to the closed-loop control system. This simple system provides a highly efficient and more reliable drive than open loop stepping systems. Other features include reduced positioning time, low vibration, energy savings, and stable stopping. Typical applications for SANMOTION Model PB Closed-Loop Stepping Systems include semiconductor manufacturing equipment, embroidery machines, monitoring cameras, and crystal blank testing devices.
