Nema 23 JKISC57-R4A3 Intelligent Integrated Stepper Servo Motor with Worm Gearbox 57x57x102mm RS485 Control 3A 2.2N.m with Built-in Driver

The JKISC57-R4A3 is a 2.2 N·m NEMA 23 integrated closed-loop stepper motor featuring RS485 communication, encoder feedback, and a built-in driver. Its specifications include 3 A phase current, 1.4 Ω resistance, and 4.5 mH inductance, with a 1.8° step angle. The motor measures 102.5 mm in body length and weighs approximately 1.3 kg, making it suitable for higher-load automation systems. Integrated encoder options include 1000 PPR, 17-bit, and 15-bit feedback. RS485 communication enables convenient integration into networked motion-control systems and multi-axis equipment. For applications requiring further speed reduction, the motor can be matched with an NMRV30 worm gearbox offering 5–80 ratios. Typical uses include conveyors, packaging machines, rotary positioning, feeders, and OEM automation equipment. For more different integrated servo stepper motor requirements please contact us!!!
