The JKISC57-R2A3 combines a NEMA 23 stepper motor, integrated driver, and encoder in one closed-loop stepper servo motor designed for digitally controlled automation. It produces 1.2 N·m rated torque, with 2.8 A phase current, 0.9 Ω phase resistance, and 3 mH phase inductance. The motor features a 1.8° step angle, 75 mm body length, and 0.8 kg weight. Its integrated encoder is available with 1000 PPR, 17-bit, or 15-bit feedback. RS485 control makes this model suitable for networked machine architectures and multi-axis applications where reduced wiring and centralized communication are important. With an optional NMRV30 worm gearbox, the JKISC57-R2A3 can provide lower output speed and higher mechanical torque for conveyors, lifting mechanisms, rotary equipment, and OEM automation systems.
