The JKISC57-C6A3 is the highest-torque model among the listed NEMA 23 ISC57 planetary geared stepper servo motors, offering 3.0 N·m rated torque, 4.2 A current, 0.9 Ω resistance, 3.8 mH inductance, and a 132 mm body length. It combines a 57 mm NEMA 23 stepper motor, integrated driver, encoder feedback, and PRF/PRL60-L planetary gearbox in one compact motion solution. CANopen control enables coordinated operation in networked multi-axis machines, while the encoder supports single-turn and multi-turn absolute encoder configurations for closed-loop positioning. The 1.8° step angle provides precise incremental motion, making this integrated planetary geared stepper motor suitable for robotics, packaging, material handling, conveyors, and industrial automation. RS485 and pulse control can also be configured according to system requirements.
