Technical Overview – YASKAWA SGM7A-02AFA61

Note: Ratings above are representative for this model range. Always confirm final values from the official YASKAWA datasheet before design or sizing decisions.

1. Role of SGM7A-02AFA61 in Automation Systems

The SGM7A-02AFA61 is a 200 W class motor, a very popular power level for light and medium-duty axes that still require “true servo” performance instead of simple induction motors or stepper systems. It is typically used in:

• X/Y/Z axes of compact machines

• High-speed feeders and indexers

• Small rotary tables and alignment fixtures

• Robotic grippers and auxiliary joints

The motor offers a strong balance between size, torque, and inertia, enabling machine builders to design fast, accurate axes without sacrificing overall machine compactness.

2. Motion Performance and Control Features

When paired with a Sigma-7 SERVOPACK drive, the YASKAWA SGM7A-02AFA61 delivers a high level of motion performance that goes significantly beyond basic positioning:

Fast Dynamic Response

The rotor and magnetic circuit are optimized for rapid acceleration and deceleration. In real production environments, this translates into:

• Shorter cycle times

• Faster indexing and pick-and-place movements

• Reduced waiting time between steps in a motion sequence

For machines running 24/7, even small reductions in cycle time add up to substantial productivity gains.

Precision Positioning and Repeatability

The built-in high-resolution encoder works together with advanced Sigma-7 control algorithms to provide:

• Excellent repeatability for start/stop positioning

• Tight following of complex motion profiles

• Minimal tracking error during contouring or synchronized movements

This level of control is particularly important in electronics manufacturing, inspection stations, and applications where product tolerances are very small.

Smooth Operation at Both Low and High Speed

The SGM7A-02AFA61 maintains smooth torque generation across its usable speed range:

• At low speed, stable rotation reduces vibration and improves process quality during slow feeds, alignment, or measuring operations.

• At higher speeds, low torque ripple supports accurate registration and contouring, which is useful in packaging, printing, and converting machinery.

3. Mechanical Design for Easy Integration

The SGM7A-02AFA61 is engineered to simplify mechanical integration and improve long-term reliability:

Standardized Mounting and Shaft

• The flange mounting pattern follows common servo motor standards, allowing direct fit to gearboxes, ball screw mounts, and machine plates.

• The straight shaft can be coupled to a range of mechanical transmission elements such as couplings, timing pulleys, or harmonic gearboxes.

This reduces the need for custom adapters and helps shorten the overall design cycle.

Compact Housing and Power Density

For a 200 W class motor, the physical size of the SGM7A-02AFA61 is impressively compact. This benefits:

• Machines with multiple parallel axes in a limited footprint

• Retrofits where space in existing equipment is extremely constrained

• Systems where keeping moving mass as low as possible is important for performance

Bearings and Structural Rigidity

The internal bearings and rotor support are specified for industrial duty:

• Designed to handle typical radial and axial loads when installed correctly

• Proper rigidity reduces deflection, improves positioning, and helps maintain low vibration levels over long service life

4. Electrical and System Integration

The electrical design of the SGM7A-02AFA61 supports clean integration into professional control architectures.

Servo Drive Compatibility

The motor is intended to operate with YASKAWA Sigma-7 SERVOPACK amplifiers. This pairing delivers:

• Fully matched motor/drive parameters for optimal torque utilization

• Automatic tuning and inertia estimation functions to reduce commissioning time

• Unified parameter structure for multiple axes in one system

Encoder and Feedback

The high-resolution encoder on the SGM7A-02AFA61 provides a fine feedback signal to the drive:

• Enables precise current, speed, and position control loops

• Supports advanced features such as electronic gearing, camming, and interpolation

• Enhances disturbance rejection when the axis is subject to external forces

Cabling and EMC

YASKAWA-compatible power and encoder cables are designed to minimize noise and ensure reliable communication between motor and drive:

• Shielded encoder lines reduce susceptibility to electrical interference

• Proper grounding and routing help maintain EMC compliance in complex machines

5. Typical Application Examples

Thanks to its compact size and 200 W class output, the SGM7A-02AFA61 shows up in a variety of machine types:

Packaging and Material Handling

• Servo-driven feed rollers for films or webs

• Small conveyor axes requiring synchronized motion

• Rotary knives and perforators that must align with moving material

Electronics and Precision Assembly

• PCB loaders/unloaders and transfer stations

• Component placement heads with fine positioning requirements

• Inspection axes where smooth, stable motion ensures clear imaging

Light Machine Tools and Cutting Systems

• Small CNC axes for drilling, routing, or engraving

• Positioning stages for fixtures and jigs

• Tool changers and index units that need fast, repeatable movement

Laboratory and Test Equipment

• Motion stages for sensors, probes, or cameras

• Automated test rigs where repeatability and controlled motion profiles are important

6. Benefits for OEMs and Integrators

Integrating the YASKAWA SGM7A-02AFA61 into a machine platform provides several long-term advantages:

• Common Platform Strategy
  Because it is part of the Sigma-7 family, engineers can build entire machines with multiple power levels (from low to higher wattage) while keeping a consistent control and maintenance concept.

• Reduced Engineering and Commissioning Time
  Automatic tuning, pre-defined motor models in the drive, and well-documented parameter sets help get new designs running quickly.

• High Reliability and Long Service Life
  YASKAWA’s proven servo technology and quality standards mean fewer unexpected stops and lower maintenance overhead when the motor is used within specification.

• Scalability and Future Expansion
  Additional axes can be added later using the same motor and drive family, simplifying upgrades or variants of the original machine.

7. Installation and Maintenance Guidelines

To fully benefit from the capabilities of the SGM7A-02AFA61, proper installation and maintenance practices are essential:

Mechanical Installation

• Ensure the mounting face is flat and rigid to avoid stress on the motor housing and bearings.

• Align the motor shaft carefully with the driven load, using quality couplings and checking for angular and parallel misalignment.

Thermal and Environmental Conditions

• Follow the specified ambient temperature and humidity limits.

• Allow sufficient airflow around the housing; natural cooling relies on unobstructed surfaces.

• In environments with dust, oil mist, or moisture, apply appropriate sealing and protection according to YASKAWA guidelines.

Electrical Setup and Tuning

• Use recommended cables and observe correct shielding and grounding methods.

• Select the exact motor model (SGM7A-02AFA61) in the servo drive settings.

• Run automatic tuning, then fine-tune parameters as needed for the specific mechanical structure and desired motion profile.

Routine Checks

• Periodically inspect cables and connectors for wear or looseness.

• Listen for unusual noises and check for abnormal vibration or excessive temperature.

• Address mechanical problems (misalignment, overload, contamination) promptly to protect the motor and machine.

8. Conclusion

The YASKAWA SGM7A-02AFA61 AC servo motor is a compact, reliable, and precise 200 W class drive solution for a wide variety of automation tasks.
