AR11 RS485 Integrated Stepper Motor (NEMA11)
Product Overview
The AR11 is an ultra-compact NEMA11 (28mm) integrated stepper motor with built-in RS485 communication, combining motor, driver, and encoder into a single space-saving package. Designed for networked motion control in compact machinery and instrumentation, the AR11 delivers holding torque from 0.08 N·m to 0.24 N·m across three motor length options (31mm, 52mm, and 63mm).
The AR11 features a working voltage range of 8-36V DC and supports RS485 communication with Modbus RTU protocol for industrial compatibility. The built-in 1000-line encoder provides closed-loop feedback, eliminating missed steps and ensuring positional integrity. With support for up to 32 devices on a single RS485 bus, the AR11 enables cost-effective multi-axis control with minimal wiring.
Each AR11 includes digital inputs for limit switches and sensors, plus a digital output for alarm signaling. The built-in program storage allows standalone operation with pre-configured motion sequences. Comprehensive protection includes overvoltage, undervoltage, overcurrent, open winding, and position deviation detection.
