The PUSI's closed-loop integrated stepper motor PMC006X1E-20 adopts Pusi's independently developed high-performance embedded drive control module, integrating the electrical drive control of 20 stepper motors into one unit. It can optionally include an internal 4000ppr incremental encoder, a multi-turn absolute encoder, or a single-turn absolute encoder, enabling high-precision control of the stepper motor without loss of steps. This series of integrated machines offers various model options based on CAN or RS-485 bus control and different current ratings. It can easily implement an industrial control network system with up to 120 nodes, significantly simplifying the complexity of the upper-level control system while maximizing the flexibility of control, making it suitable for various high-precision, wide-range industrial applications.
