Within the Sigma-7 lineup, the SGM7A-A5AFA61 occupies a mid-power slot, ideal for axes that handle meaningful mechanical loads but still demand compact size and precise control. It strikes a balance between torque capability and physical footprint, making it especially well suited to:
Main and auxiliary axes in packaging and filling machines
Rotary or linear axes in compact machine tools
Robotic joints with moderate payloads
Indexing tables, feeders, and transfer units
Because it belongs to the Sigma-7 ecosystem, it shares the same control philosophy, encoder technology, and drive compatibility as other SGM7A motors, allowing designers to mix power levels across a machine while maintaining a unified platform.
The SGM7A-A5AFA61 is built around a high-efficiency AC synchronous rotor and a high-resolution encoder. Together with a Sigma-7 SERVOPACK, it provides:
High Dynamic Response
The motor is designed for fast acceleration and deceleration, allowing short cycle times and sharp positioning. This is particularly beneficial in pick-and-place operations, flying shear applications, labeling stations, and any motion profile with frequent reversals.
Excellent Positioning Accuracy
Fine encoder resolution, combined with advanced servo algorithms, ensures tight position control and repeatable results. This reduces scrap, improves product consistency, and enables higher precision processes such as electronics assembly or high-speed inspection.
Stable High-Speed Operation
The SGM7A-A5AFA61 maintains smooth rotation over a broad speed range. Even at higher speeds, vibration and torque ripple are minimized, supporting accurate contouring, smooth feeding, and reliable synchronization with other machine elements.
Superior Low-Speed Behavior
Many critical processes run at low speed for alignment, measuring, or forming. The motor’s low cogging design and encoder feedback help deliver quiet, stable motion at very low speeds, keeping positioning and force control consistent.
The mechanical design of the SGM7A-A5AFA61 is optimized for easy integration into modern industrial equipment:
Standardized Flange and Shaft Geometry
The flange mounting pattern follows typical servo standards, simplifying direct mounting to gearboxes, linear modules, or custom frames. The straight shaft allows flexible coupling to ball screws, timing belts, or rigid couplings.
Compact, High-Power Density Housing
The motor’s outer dimensions are compact relative to its torque and power class. This is valuable for machine builders trying to reduce cabinet size, shorten mechanical chains, or fit multiple axes into narrow spaces.
Robust Bearings and Structural Rigidity
Internal bearings and rotor support structures are selected for long life under continuous industrial loading. Proper alignment and adherence to rated radial/axial loads result in long-term reliability and quiet operation.
Efficient Thermal Management
The motor housing is shaped to dissipate heat effectively under natural convection. When installed according to YASKAWA guidelines, it can maintain safe temperatures in continuous operation within the specified ambient range.
Clean Cable Routing
Power and encoder connectors are positioned for practical routing in machines and panels. Compatible YASKAWA servo cables help ensure proper shielding, EMC performance, and reliable feedback transmission.
The SGM7A-A5AFA61 is intended to be operated by Sigma-7 SERVOPACK servo amplifiers, which unlock the motor’s full performance potential:
Automatic Tuning and Load Identification
Servo drives can perform auto-tuning routines that detect mechanical characteristics such as load inertia and compliance. This shortens setup time and helps even non-experts achieve stable control results.
Advanced Vibration Suppression
Built-in filters and vibration suppression functions reduce oscillation in flexible systems, including long arms, belt drives, or lightly damped frames. This enables faster positioning without excessive overshoot or ringing.
Flexible Communication Interfaces
Depending on the SERVOPACK version, fieldbus and network options can include EtherCAT, MECHATROLINK, and other industrial networks. This allows the SGM7A-A5AFA61 to fit into diverse PLC and motion control architectures.
Diagnostics and Safety
Drives provide extensive alarm information, status monitoring, and optional safety functions such as Safe Torque Off (STO). This simplifies troubleshooting and supports machine safety compliance when correctly integrated.
The YASKAWA SGM7A-A5AFA61 is a versatile mid-power servo motor that can be found in a wide array of machinery:
Packaging and Filling Equipment
Used for film feed axes, sealing head positioning, conveyor synchronization, and cutting or perforating stations. High responsiveness directly increases line speed and throughput.
Machine Tools and Small CNC Systems
Applied on feed axes, rotary tables, tool changers, or auxiliary axes requiring precise interpolation and smooth contouring.
Robotics and Handling Systems
Suitable for joints, gantry axes, and loaders where moderate payloads and fast cycle times are required, alongside accurate path tracking.
Printing, Labeling, and Converting Machines
Ensures accurate web tension control, register alignment, and repeatable indexing of labels, cutting dies, or printing cylinders.
Electronics Manufacturing and Assembly
Ideal for component placement, inspection stages, and small fixture motions that require repeatable micro-positioning and low vibration.
Choosing the SGM7A-A5AFA61 as part of a motion system offers several practical benefits:
Unified Servo Platform
The Sigma-7 family allows machine builders to use a consistent motor and drive platform from low to higher power ratings, simplifying inventory, engineering, and support.

Energy-Efficient Operation
Efficient windings and modern control algorithms help to reduce energy usage, especially in multi-axis systems that run continuously in production environments.
To achieve the best results from the SGM7A-A5AFA61, several practical points should be observed:
Mounting and Alignment
Ensure the mounting surface is rigid and flat. Misalignment between the motor shaft and the driven load should be minimized through careful installation and the use of quality couplings.
Environmental Conditions
Follow the specified ambient temperature, humidity, and contamination limits. In dusty or oily environments, suitable sealing and protective measures should be implemented.
Cabling and Grounding
Use recommended power and encoder cables, and route them away from high-frequency noise sources where possible. Proper grounding improves EMC behavior and feedback reliability.
Parameter Setting and Testing
After wiring, select the correct motor model in the drive parameters, run auto-tuning, and verify motion response at low speed before moving to full-speed testing.
Routine Inspection
Periodically check connector tightness, cable condition, unusual noise, and operating temperature. Early detection of mechanical or electrical issues helps prevent unplanned downtime.
