MODBUS RTU NEMA24 Absolute Encoder Integrated Stepper Motor (IM24ET)
Product Link
[edit]Description
[edit]The IM24ET Series integrated motors perfectly integrate stepper drivers and stepper motors into a single, compact unit. Fully compatible with 1599-revolution mechanical absolute encoders, they save installation space and simplify wiring connections while reducing design and production costs.
With a holding torque range of 1.1-3.5 N.m and supply voltage of 24-60 VDC, these NEMA24 motors deliver the power needed for medium-duty automation tasks. They support Modbus/RTU over RS485 for easy network integration.
The built-in programmable multi-turn feedback supports user-defined home position with memory - no sensor required. The software limit function is more reliable than mechanical limit switches.
