IM23ET Absolute Encoder Integrated Stepper Motor (NEMA23)
Product Overview
The IM23ET is a NEMA23 (57mm) integrated stepper motor featuring a single-turn absolute encoder with Modbus RTU communication. This high-performance all-in-one solution combines a stepper motor, driver, and absolute encoder in a rugged 57mm frame, delivering holding torque from 0.45 N·m to 2.50 N·m. The absolute encoder retains exact rotor position through power cycles, making the IM23ET ideal for industrial applications where homing downtime must be eliminated.
The IM23ET supports Modbus RTU protocol over RS485 for direct integration with industrial automation systems, including PLCs from Siemens, Allen-Bradley, Mitsubishi, and Omron. The closed-loop feedback ensures no missed steps even under heavy load conditions, while the absolute encoder provides immediate position knowledge after power-up. Operating on 12-48V DC with driver current up to 4.5A, the IM23ET delivers robust performance for medium-duty industrial applications.
The all-in-one design eliminates the need for separate driver panels and encoder wiring, significantly reducing installation time and cabinet space requirements. Comprehensive protection includes overvoltage, undervoltage, overcurrent, open winding, and position deviation detection. The 6.35mm shaft diameter ensures reliable torque transmission.
