ABB 3AXD50000041266 eSM Servo Motor - Absolute Encoder
Part Number: 3AXD50000041266
Quick Summary
ABB eSM servo motor is a high-precision drive designed for fast, accurate motion in automated manufacturing and packaging lines. It delivers reliable torque and rapid dynamic response to boost throughput while reducing cycle times. A common pain point is long machine set-up and frequent calibration, which this motor mitigates with an absolute encoder that eliminates repeated homing. In practice, you’ll encounter CE conformity and, where applicable, IP protection ratings to support safety and reliability in European operations and harsh environments. Leveraging ABB's servo ecosystem — including MotiFlex e180 and MicroFlex e190 drives — delivers a cohesive controller and optimized energy use, enabling scalable automation and lower total cost of ownership.

FAQs
When pairing the ABB eSM servo motor with MotiFlex e180, verify flange compatibility and connect the encoder interface according to the drive’s wiring diagram. Ensure correct voltage supply of 220 V and set motor parameters for the 2 kW/9.55 N·m rating. Use ABB documentation to map feedback types (incremental vs absolute) and enable the encoder for quick homing or zero-set positioning. The result is a smoother commissioning process and reduced startup time.
You can expect strong torque density with rapid acceleration and deceleration, enabling high-speed positioning and precise load handling. The 2 kW rating at 220 V supports reliable continuous operation in demanding applications, while the 9.55 N·m torque provides robust performance for mid-to-large payloads. When integrated with the ABB drive family, you gain cohesive control loops, improved energy efficiency, and predictable motion profiles essential for repetitive packaging and assembly tasks.
The absolute encoder eliminates the need for homing cycles during commissioning, which significantly reduces machine setup time between changeovers. This improves line uptime and enables faster ramp-up to production. For operators, it means quicker alignment of axes and more repeatable positioning across runs, leading to greater overall line efficiency and less manual calibration.
Confirm CE conformity as a baseline for European operations and check IP protection ratings where the application exposes components to dust, water, or contaminants. For safety-critical systems, ensure compatibility with the plant’s SIL-rated controls and the overall safety architecture. While the motor meets standard industrial requirements, always verify site-specific regulatory and sector requirements before installation.
The ROI comes from increased throughput due to faster cycle times and reduced downtime from quick setup with absolute encoding. Energy-efficient operation lowers operating costs over the motor’s life, while reliable performance minimizes scrap and rework. Integration with ABB’s drive ecosystem also reduces maintenance complexity and extends equipment life, delivering measurable cost savings on a typical automation upgrade.
