IM34ET Absolute Encoder Integrated Stepper Motor (NEMA34)
Product Overview
The IM34ET is a NEMA34 (86mm) integrated stepper motor featuring a single-turn absolute encoder with Modbus RTU communication. This is the highest torque option in Adampower's absolute encoder lineup, delivering holding torque from 2.00 N·m to 8.00 N·m in a rugged 86mm frame. The IM34ET is designed for the most demanding industrial applications where absolute position retention through power cycles is critical.
The IM34ET supports Modbus RTU protocol over RS485 for direct integration with industrial PLCs and SCADA systems. Operating on 12-70V DC with driver current up to 8.0A, this motor provides exceptional torque for heavy industrial applications. The 14mm shaft diameter ensures maximum torque transmission capability, while the absolute encoder provides immediate position knowledge after any power interruption, eliminating the need for time-consuming homing sequences.
The all-in-one design integrates motor, driver, and absolute encoder into a single housing, dramatically simplifying system integration and reducing cabinet space. Comprehensive protection includes overvoltage, undervoltage, overcurrent, open winding, and position deviation detection. The built-in program capability enables standalone operation with pre-configured motion sequences.
