FAQs
Yes. The eSM servo motor is designed to integrate with ABB MotiFlex e180 and MicroFlex e190 drives, enabling plug-and-play parameterization and consistent communication. This reduces commissioning time, aligns axis synchronization, and simplifies system architecture. Always verify connector types, feedback options, and torque mapping in the latest installation manual.
The motor is rated for 7.5 kW at 400 V AC with a nominal torque of 48 Nm. The eSM encoder provides precise position feedback, supporting high-accuracy motion across demanding applications. For specific torque curves and speed ranges, refer to the official datasheet and motor parameter file for your drive configuration.
Yes. An absolute encoder option eliminates homing cycles, speeds up machine commissioning, and reduces setup time between changeovers. This is particularly valuable in high‑mix manufacturing where downtime directly impacts throughput and productivity. Ensure your control system and drive support absolute encoding when selecting options.
ABB notes that the eSM motor is available in various flange sizes, offering flexibility for retrofit projects and new lines alike. When planning installation, verify flange compatibility, shaft dimensions, mounting pattern, and enclosure space. Proper alignment and pre-commissioning checks with MotiFlex or MicroFlex drives help prevent control loop issues and ensure reliable performance.
