IM24ET Absolute Encoder Integrated Stepper Motor (NEMA24)
Product Overview
The IM24ET is a NEMA24 (60mm) integrated stepper motor featuring a single-turn absolute encoder with Modbus RTU communication. This powerful all-in-one solution combines a stepper motor, driver, and absolute encoder in a robust 60mm frame, delivering holding torque from 1.20 N·m to 4.50 N·m. The IM24ET is designed for medium-to-heavy industrial applications requiring immediate position recovery after power loss.
The IM24ET supports Modbus RTU protocol over RS485 for seamless integration with industrial control networks. The single-turn absolute encoder provides 4096 positions per revolution, ensuring exact position knowledge within a 360-degree range after any power interruption. Operating on 12-70V DC with driver current up to 6.0A, the IM24ET provides substantial torque for demanding applications.
The integrated design dramatically reduces system complexity compared to discrete solutions, eliminating external driver mounting, encoder cabling, and the associated electromagnetic compatibility issues. The 8mm shaft diameter provides robust torque transmission for high-inertia loads. Comprehensive protection includes overvoltage, undervoltage, overcurrent, open winding, and position deviation detection.
