MODBUS RTU NEMA34 Integrated Stepper Motor (IM34ET)
Product Link
[edit]Description
[edit]The IM34ET Series integrated motors combine stepper drivers and stepper motors into a single, powerful unit. They are fully compatible with 1599-revolution mechanical absolute encoders, saving installation space and streamlining wiring connections while reducing design and production costs.
With a substantial holding torque range of 4.5-12.5 N.m and an AC supply voltage of 18-70 VAC (or 24-100 VDC), these NEMA34 motors are built for heavy-duty industrial applications. They support Modbus/RTU over RS485 for easy integration into factory automation networks.
The built-in programmable multi-turn feedback supports user-defined home position with memory - no sensor required. Software limit functions replace mechanical limit switches for improved reliability.
