Nema 11 JKISC28-R1A3 Integrated Linear Motion with Integrated Stepper Servo Motor 28x28x48.1mm 1.0A 0.065N.m with RS485 Control

The JKISC28-R1A3 NEMA 11 integrated linear motion combines a 28 × 28 mm stepper motor with an integrated servo driver and is designed for RS485 Modbus RTU control. Its key specifications include a 48.1 mm body length, 1.0 A current, 2.8 Ω resistance, 1.8 mH inductance, 0.065 N·m rated torque, 1.8° step angle, and 1000 PPR / 17-bit / 15-bit encoder options. The motor supports DC 12–36 V operation and can also be configured for Pulse or CANopen communication.

For machine builders that need networked NEMA 11 linear motion, the JKISC28-R1A3 offers a compact alternative to a conventional stepper motor plus external driver. RS485 Modbus RTU enables integration into centralized automation architectures, while the built-in driver, intelligent current control, high-speed 200 kHz pulse capability, and optional IP30/IP54/IP65 protection help simplify system design. It is particularly relevant to compact industrial automation, medical equipment, logistics equipment, textile machinery, and precision linear positioning systems.
